-
-## General Workflow
-
-1. Push to a remote branch
-2. Create an MR, choose related labels (not required)
-3. A `detached` pipeline will be created.
-4. if you push a new commit, a new pipeline will be created automatically.
-
-## What if Expected Jobs ARE NOT Created?
-
-1. check the file patterns
-
-   If you found a job that is not running as expected with some file changes, a git commit to improve the `pattern` will be appreciated.
-
-2. please add MR labels to run additional tests, currently we have to do this only for `target-test` jobs, please use it as few as possible. Our final goal is to remove all the labels and let the file changes decide everything!
-
-## MR labels for additional jobs
-
-### Supported MR Labels
-
-- `build`
-- `build_docs`
-- `component_ut[_esp32/esp32s2/...]`
-- `custom_test[_esp32/esp32s2/...]`
-- `docker`
-- `docs`
-- `docs_fast`, triggers a fast docs build, not a full build which is the CI default. This skips PDF build as well as doxygen APIs, reducing the build time by 90+%.
-- `example_test[_esp32/esp32s2/...]`
-- `fuzzer_test`
-- `host_test`
-- `integration_test`
-- `iperf_stress_test`
-- `macos`
-- `macos_test`
-- `nvs_coverage`
-- `submodule`
-- `unit_test[_esp32/esp32s2/...]`
-- `weekend_test`
-- `windows`
-
-There are two general labels (not recommended since these two labels will trigger a lot of jobs)
-
-- `target_test`: includes all target for `example_test`, `custom_test`, `component_ut`, `unit_test`, `integration_test`
-- `all_test`: includes all test labels
-
-### How to trigger a `detached` pipeline without pushing new commits?
-
-Go to MR web page -> `Pipelines` tab -> click `Run pipeline` button.
-
-In very rare case, this tab will not show up because no merge_request pipeline is created before. Please use web API then.
-
-```shell
-curl -X POST --header "PRIVATE-TOKEN: [YOUR PERSONAL ACCESS TOKEN]" [GITLAB_SERVER]/api/v4/projects/103/merge_requests/[MERGE_REQUEST_IID]/pipelines
-```
-
-## How to Develop With `rules.yml`?
-
-### General Concepts
-
-- `pattern`: Defined in an array. A GitLab job will be created if the changed files in this MR matched one of the patterns. For example:
-
-    ```yaml
-    .patterns-python-files: &patterns-python-files
-      - "**/*.py"
-    ```
-
-- `label`: Defined in an if clause, similar as the previous bot command. A GitLab job will be created if the pipeline variables contains variables in `BOT_LABEL_xxx` format (DEPRECATED) or included in the MR labels. For example:
-
-    ```yaml
-    .if-label-build_docs: &if-label-build_docs
-      if: '$BOT_LABEL_BUILD_DOCS || $CI_MERGE_REQUEST_LABELS =~ /^(?:[^,\n\r]+,)*build_docs(?:,[^,\n\r]+)*$/i'
-    ```
-
-- `rule`: A combination of various patterns, and labels. It will be used by GitLab YAML `extends` keyword to tell GitLab in what conditions will this job be created. For example:
-
-    ```yaml
-    .rules:build:docs:
-      rules:
-        - <<: *if-protected
-        - <<: *if-label-build_docs
-        - <<: *if-label-docs
-        - <<: *if-dev-push
-          changes: *patterns-docs
-    ```
-
-  An example for GitLab job on how to use extends:
-
-    ```yaml
-    check_docs_lang_sync:
-      extends:
-        - .pre_check_template
-        - .rules:build:docs
-      script:
-        - cd docs
-        - ./check_lang_folder_sync.sh
-    ```
-
-### How to Add a New `Job`?
-
-check if there's a suitable `.rules:<rules-you-need>` template
-
-1. if there is, put this in the job `extends`. All done, now you can close this window. (`extends` could be array or string)
-2. if there isn't
-    1. check [How to Add a New `Rules` Template?](#how-to-add-a-new-rules-template), create a suitable one
-    2. follow step 1
-
-### How to Add a New `Rules` Template?
-
-check if this rule is related to `labels`, `patterns`
-
-1. if it is, please refer to [dependencies/README.md](./dependencies/README.md) and add new rules by auto-generating
-2. if it isn't, please continue reading
-
-check if there's a suitable `.if-<if-anchor-you-need>` anchor
-
-1. if there is, create a rule following [`rules` Template Naming Rules](#rules-template-naming-rules).For detail information, please refer to [GitLab Documentation `rules-if`](https://docs.gitlab.com/ee/ci/yaml/README.html#rulesif). Here's an example.
-
-    ```yaml
-    .rules:patterns:python-files:
-      rules:
-        - <<: *if-protected
-        - <<: *if-dev-push
-          changes: *patterns-python-files
-    ```
-
-2. if there isn't
-
-    1. check [How to Add a New `if` Anchor?](#how-to-add-a-new-if-anchor), create a suitable one
-    2. follow step 1
-
-### How to Add a New `if` Anchor?
-
-Create an `if` anchor following [`if` Anchors Naming Rules](#if-anchors-naming-rules). For detailed information about how to write the condition clause, please refer to [GitLab Documentation `only/except (advanced)](https://docs.gitlab.com/ee/ci/yaml/README.html#onlyexcept-advanced). Here's an example.
-
-```yaml
-.if-schedule: &if-schedule:
-  if: '$CI_PIPELINE_SOURCE == "schedule"'
-```
-
-### Naming Rules
-
-#### Common Naming Rules
-
-if a phrase has multi words, use `_` to concatenate them.
-
-> e.g. `regular_test`
-
-if a name has multi phrases, use `-` to concatenate them.
-
-> e.g. `regular_test-example_test`
-
-#### `if` Anchors Naming Rules
-
-- if it's a label: `.if-label-<label_name>`
-- if it's a ref: `.if-ref-<ref_name>`
-- if it's a branch: `.if-branch-<branch_name>`
-- if it's a tag: `.if-tag-<tag_name>`
-- if it's multi-type combination: `.if-ref-<release_name>-branch-<branch_name>`
-
-  **Common Phrases/Abbreviations**
-
-    - `no_label`
-
-      `$BOT_TRIGGER_WITH_LABEL == null`
-
-    - `protected`
-
-      `($CI_COMMIT_REF_NAME == "master" || $CI_COMMIT_BRANCH =~ /^release\/v/ || $CI_COMMIT_TAG =~ /^v\d+\.\d+(\.\d+)?($|-)/)`
-
-    - `target_test`
-
-      a combination of `example_test`, `custom_test`, `unit_test`, `component_ut`, `integration_test` and all targets
-
-#### `rules` Template Naming Rules
-
-- if it's tag related: `.rules:tag:<tag_1>-<tag_2>`
-- if it's label related: `.rules:labels:<label_1>-<label_2>`
-- if it's test related: `.rules:test:<test_type>`
-- if it's build related: `.rules:build:<build_type>`
-- if it's pattern related: `.rules:patterns:<patterns>`
-
-## Reusable Shell Script `tools/ci/utils.sh`
-
-It is used to put all the reusable shell scripts as small functions. If you want to set `before_script: []` for you job, now you can set `extends: .before_script_slim` instead. it will only run `source tools/ci/utils.sh`
-
-If you're developing CI shell scripts, you can use these functions without `source` them. They're already included in all `before_script`
-
-To run these commands in shell script locally, place `source tools/ci/utils.sh` at the very beginning.
-
-### Functions
-
-#### CI Job Related
-
-- `add_gitlab_ssh_keys`
-- `add_github_ssh_keys`
-- `add_doc_server_ssh_keys`
-- `fetch_submodules`
-- `get_all_submodules`
-
-#### Shell Script Related
-
-- `error`: log in red color
-- `warning`: log in orange color
-- `info`: log in green color
-- `run_cmd`: run the command with duration seconds info
-- `retry_failed`: run the command with duration seconds info, retry when failed
-
-## Manifest File to Control the Build/Test apps
-
-`.build-test-rules.yml` file is a manifest file to control if the CI is running the build and test job or not. The Supported Targets table in `README.md` for apps would be auto-generated by `pre-commit` from the app's `.build-test-rules.yml`.
-
-### Grammar
-
-#### Operands
-
-- Variables start with `SOC_`. The value would be parsed from components/soc/[TARGET]/include/soc/*_caps.h
-- `IDF_TARGET`
-- `INCLUDE_DEFAULT` (The default value of officially supported targets is 1, otherwise is 0)
-- String, must be double-quoted. e.g. `"esp32"`, `"12345"`
-- Integer, support decimal and hex. e.g. `1`, `0xAB`
-- List with String and Integer inside, the type could be mixed. e.g. `["esp32", 1]`
-
-#### Operators
-
-- `==`, `!=`, `>`, `>=`, `<`, `<=`
-- `and`, `or`
-- `in`, `not in` with list
-- parentheses
-
-#### Limitation:
-
-- all operators are binary operator. For more than two operands, you may use nested parentheses trick. For example,
-  - `A == 1 or (B == 2 and C in [1,2,3])`
-  - `(A == 1 and B == 2) or (C not in ["3", "4", 5])`
-
-### How does it work?
-
-By default, we enable build and test jobs for supported targets. In other words, if an app supports all supported targets, it does not need to be added in a manifest file. The manifest files are files that set the violation rules for apps.
-
-three rules (disable rules are calculated after the `enable` rule):
-- enable: run CI build/test jobs for targets that match any of the specified conditions only
-- disable: will not run CI build/test jobs for targets that match any of the specified conditions
-- disable_test: will not run CI test jobs for targets that match any of the specified conditions
-
-Each key is a test folder. Will apply to all folders inside.
-
-If one sub folder is in a special case, you can overwrite the rules for this folder by adding another entry for this folder itself. Each folder's rules are standalone, and will not inherit its parent's rules. (YAML inheritance is too complicated for reading)
-
-For example in the following codeblock, only `disable` rule exists in `examples/foo/bar`. It's unaware of its parent's `enable` rule. 
-
-```yaml
-examples/foo:
-  enable:
-    - if: IDF_TARGET == "esp32"
-
-examples/foo/bar:
-  disable:
-    - if: IDF_TARGET == "esp32s2"
-```
-
-### Example
-
-```yaml
-examples/foo:
-  enable:
-    - if IDF_TARGET in ["esp32", 1, 2, 3]
-    - if IDF_TARGET not in ["4", "5", 6]
-  # should be run under all targets!
-
-examples/bluetooth:
-  disable:  # disable both build and tests jobs
-    - if: SOC_BT_SUPPORTED != 1
-    # reason is optional if there's no `temporary: true`
-  disable_test:
-    - if: IDF_TARGET == "esp32"
-      temporary: true
-      reason: lack of ci runners  # required when `temporary: true`
-
-examples/bluetooth/test_foo:
-  # each folder's settings are standalone
-  disable:
-    - if: IDF_TARGET == "esp32s2"
-      temporary: true
-      reason: no idea
-  # unlike examples/bluetooth, the apps under this folder would not be build nor test for "no idea" under target esp32s2
-
-examples/get-started/hello_world:
-  enable:
-    - if: IDF_TARGET == "linux"
-      reason: this one only supports linux!
-
-examples/get-started/blink:
-  enable:
-    - if: INCLUDE_DEFAULT == 1 or IDF_TARGET == "linux"
-      reason: This one supports all supported targets and linux

-# How the `generate_rules.py` works
-
-## Functionalities
-
-This script can do only two things:
-
-1. Auto-generate some labels/rules we need and update them in `rules.yml`
-2. Generate a dependency tree graph
-
-## Schema
-
-This file only used basic YAML grammar and has nothing to do with the GitLab version YAML file.
-
-It has five custom keywords:
-
-- `matrix`: An array of sub-arrays, used to replicate rules by formatting strings. You can use the format string everywhere, it will be formatted recursively
-- `labels`: An array of `labels`.
-- `patterns`: An array of `patterns`. Patterns that not included
-- `included_in`: An array of other `rule` names. It indicates the `labels` and `patterns` will be included in all specified `rules` as well
-- `deploy`: An array of strings, used to replicate rules by adding postfix `-<item in deploy array>`. It indicates the extra `label` used in `rules`, which will explain later.
-
-## How to use this file to generate `rules.yml`
-
-Let's take a complicated example to help understand the process
-
-```yaml
-"test-{0}-{1}":
-    matrix:
-        - [a, b]
-        - [c, d]
-    labels:
-        - "{0}-{1}"
-    patterns:
-        - "{0}"
-        - pattern-not-exist
-    included_in:
-        - build-{0}
-```
-
-1. expand the mapping dicts defined by `matrix`
-
-   After this step, it will turn into 4 dicts:
-
-   | key      | labels | patterns | included_in |
-   | -------- | ------ | -------- | ----------- |
-   | test-a-c | a-c    | a        | build-a     |
-   | test-a-d | a-d    | a        | build-a     |
-   | test-b-c | b-c    | b        | build-b     |
-   | test-b-d | b-d    | b        | build-b     |
-
-   **Advanced Usage: You can overwrite a mapping by declaring it again later**, For example:
-
-   If we concatenate this part to the previous example,
-
-    ```yaml
-    # ... The same as the previous example
-    
-    test-a-c:
-        labels:
-            - overwrite
-    ```
-
-   `rule` `test-a-c` will be turned into:
-
-   | key      | labels    |
-   | -------- | --------- |
-   | test-a-c | overwrite |
-
-   **Mappings with the keyword `deploy` will also replicate by adding a postfix `-<item in deploy array>` to the mapping key**
-
-2. create rules by `included_in`
-
-   After this step, it will turn into 6 mapping dicts:
-
-   | key      | labels   | patterns |
-   | -------- | -------- | -------- |
-   | test-a-c | a-c      | a        |
-   | test-a-d | a-d      | a        |
-   | test-b-c | b-c      | b        |
-   | test-b-d | b-d      | b        |
-   | build-a  | a-c, a-d | a        |
-   | build-b  | b-c, b-d | b        |
-
-3. replace the auto-generated region in `rules.yml` with `labels`, and `rules`. Each mapping will generate a `rule` and all the required labels. `patterns` are pre-defined in `rules.yml` and could not be generated automatically. If a mapping is using a `pattern` undefined, the `pattern` will be ignored.
-
-    - If a mapping key has postfix `-preview`, no `if-protected-xxx` clause will be added
-    - else if a mapping key has postfix `-production`, an `if-protected-no_label` clause will be added
-    - else, an `if-protected` clause will be added
-
-## Graph
-
-All `label` nodes are in green, `pattern` nodes are in cyan, `rule` nodes are in blue
-
-### Requirements
-
-There are a few extra dependencies while generating the dependency tree graph, please refer to [pygraphviz](https://github.com/pygraphviz/pygraphviz/blob/master/INSTALL.txt) documentation to install both `graphviz` and `pygraphviz`
-
-### CLI usage
-
-`python generate_rules.py --graph OUTPUT_PATH`

-## Checklist
-
-_This entire section can be deleted if all items are checked._
-
-* [ ] Enough information to help reviewers understand the issue, its root cause, impact, and the proposed solution
-* [ ] Enough information to help reviewers understand the feature, its functional description, example, documentation, test cases, test results, feature TODO list
-* [ ] The MR Title describes the change, including the component name, ie "lwip: Add support for IP over Pigeon"
-* [ ] All related links, including JIRA, backport, submodule MR, are mentioned in the `Related` subsection.
-* [ ] Any GitHub issues are linked inside the git commit message and corresponding release notes
-* [ ] Add label for the area this MR is part of
-* [ ] For documentation updates, check if label `Docs` and `needs translation:CN` or `needs translation:EN`  have been added when the other language version still needs the update. Skip adding the label if the document is not yet translated.
-* [ ] Check if documents requiring translation fall under get-started section. If yes, add the labels mentioned above. Then the documentation team will assign a translator for you. Please inform the translator to prepare translation once your MR is ready to merge. The translation should be included in your MR to get it merged. For more information, see documentation workflow in Wiki.
-* [ ] Any necessary "needs backport" labels are added
-* [ ] Check if this is a breaking change. If it is, add notes to the `Breaking change notes` subsection below
-* [ ] Release note entry if this is a new public feature, or a fix for an issue introduced in the previous release.
-* [ ] The commit log is clean and ready to merge.
-* [ ] All relevant CI jobs have been run, i.e. jobs which cover the code changed by the MR.

-
-_For issues, put enough information here to help reviewers understand the issue, its root cause, impact, and the proposed solution._
-
-_If this issue is a regression, specify in the `Related` subsection below, in which commit or MR it was introduced. This helps reviewers to check if the backport labels are set correctly._
-
----
-
-_For features, put enough information here to help reviewers understand the feature, its functional description, example, documentation, test cases, test results, feature TODO list._
-
----
-
-_For other small/non-public changes, which are not expected to be in the release notes, can be mentioned here, include:_
-
- * changes that don't apply to customers, e.g. some CI fixes, test only MR and etc
-
-## Related
-
-* Mention or related JIRA tasks (e.g. IDF-0000), to make sure they get updated.
-* Mention submodule MR, if there is
-* Mention backport(ed) MR, if there is
-
-_Don't touch the subsection titles below, they will be parsed by scripts._
-
-## Release notes (Mandatory)
-
-_Changes made in this MR that should go into the **Release Notes** should be listed here. Please use **past tense** and *specify the area (see maintainers page of IDF internal wiki)*. If there is a subscope, include it and separate with slash (`/`). Minor changes can go to the descriptions above without a release notes entry._
-
-_Write all the changes in a **list** (Start at the beginning of the line with `-` or `*`). If multiple changes are made, each of them should take a single line. If there is only one change to list, it should still be the only line of a list. If this MR does not need any release notes, write "No release notes" here without the `-` or `*`. e.g._
-
-* [WiFi] Changed/fixed/updated xxx
-* [WiFi] Added support of xxx
-* [Peripheral Drivers/I2S] Fixed xxx (https://github.com/espressif/esp-idf/issues/xxxx)
-
-## Breaking change notes
-
-_Remove this subsection if not used._
-
-_If there are any breaking changes, please mention it here. Talking about (1) what is not accepted any more, (2) the alternative solution and (3) the benefits/reason. e.g._
-
-_Please strictly follow the breaking change restriction, which means, if there is a breaking change but you are merging to non-major versions, you have to separate the breaking part out to another MR for a major version. The breaking change subsection is only accepted in MRs merging to major versions._
-
-* [VFS/UART] Now vfs_uart_set_rts_cts accept one more instance argument, to support configuration to different ports.

+Contributions Guide
+===================
+
+We welcome contributions to the esp-idf project!
+
+How to Contribute
+-----------------
+
+Contributions to esp-idf - fixing bugs, adding features, adding documentation - are welcome. We accept contributions via `Github Pull Requests <https://help.github.com/articles/about-pull-requests/>`_.
+
+Before Contributing
+-------------------
+
+Before sending us a Pull Request, please consider this list of points:
+
+* Is the contribution entirely your own work, or already licensed under an Apache License 2.0 compatible Open Source License? If not then we unfortunately cannot accept it.
+
+* Does any new code conform to the esp-idf :doc:`Style Guide <style-guide>`?
+
+* Does the code documentation follow requirements in :doc:`documenting-code`?
+
+* Is the code adequately commented for people to understand how it is structured?
+
+* Is there documentation or examples that go with code contributions? There are additional suggestions for writing good examples in :idf:`examples` readme.
+
+* Are comments and documentation written in clear English, with no spelling or grammar errors?
+
+* Example contributions are also welcome. Please check the :doc:`creating-examples` guide for these.
+
+* If the contribution contains multiple commits, are they grouped together into logical changes (one major change per pull request)? Are any commits with names like "fixed typo" `squashed into previous commits <http://eli.thegreenplace.net/2014/02/19/squashing-github-pull-requests-into-a-single-commit/>`_?
+
+* If you're unsure about any of these points, please open the Pull Request anyhow and then ask us for feedback.
+
+Pull Request Process
+--------------------
+
+After you open the Pull Request, there will probably be some discussion in the comments field of the request itself.
+
+Once the Pull Request is ready to merge, it will first be merged into our internal git system for in-house automated testing.
+
+If this process passes, it will be merged onto the public github repository.
+
+Legal Part
+----------
+
+Before a contribution can be accepted, you will need to sign our :doc:`contributor-agreement`. You will be prompted for this automatically as part of the Pull Request process.

-                Select the way the application is built.
-
-                By default, the application is built as a binary file in a format compatible with
-                the ESP-IDF bootloader. In addition to this application, 2nd stage bootloader is
-                also built. Application and bootloader binaries can be written into flash and
-                loaded/executed from there.
-
-                Another option, useful for only very small and limited applications, is to only link
-                the .elf file of the application, such that it can be loaded directly into RAM over
-                JTAG. Note that since IRAM and DRAM sizes are very limited, it is not possible to
-                build any complex application this way. However for kinds of testing and debugging,
-                this option may provide faster iterations, since the application does not need to be
-                written into flash.
-                Note that at the moment, ESP-IDF does not contain all the startup code required to
-                initialize the CPUs and ROM memory (data/bss). Therefore it is necessary to execute
-                a bit of ROM code prior to executing the application. A gdbinit file may look as follows (for ESP32):
-
-                    # Connect to a running instance of OpenOCD
-                    target remote :3333
-                    # Reset and halt the target
-                    mon reset halt
-                    # Run to a specific point in ROM code,
-                    #  where most of initialization is complete.
-                    thb *0x40007d54
-                    c
-                    # Load the application into RAM
-                    load
-                    # Run till app_main
-                    tb app_main
-                    c
-
-                Execute this gdbinit file as follows:
-
-                    xtensa-esp32-elf-gdb build/app-name.elf -x gdbinit
-
-                Example gdbinit files for other targets can be found in tools/test_apps/system/gdb_loadable_elf/
-
-                Recommended sdkconfig.defaults for building loadable ELF files is as follows.
-                CONFIG_APP_BUILD_TYPE_ELF_RAM is required, other options help reduce application

-Espressif SoCs released before 2016 (ESP8266 and ESP8285) are supported by [RTOS SDK](https://github.com/espressif/ESP8266_RTOS_SDK) instead.
+ESP-IDF is the official development framework for the [ESP32](https://espressif.com/en/products/hardware/esp32/overview) chip.
 
 # Developing With ESP-IDF
 
 ## Setting Up ESP-IDF
 
-See https://idf.espressif.com/ for links to detailed instructions on how to set up the ESP-IDF depending on chip you use.
+See setup guides for detailed instructions to set up the ESP-IDF:
 
-**Note:** Each SoC series and each ESP-IDF release has its own documentation. Please see Section [Versions](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/versions.html) on how to find documentation and how to checkout specific release of ESP-IDF.
-
-### Non-GitHub forks
-
-ESP-IDF uses relative locations as its submodules URLs ([.gitmodules](.gitmodules)). So they link to GitHub. If ESP-IDF is forked to a Git repository which is not on GitHub, you will need to run the script [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh) after git clone.
-
-The script sets absolute URLs for all submodules, allowing `git submodule update --init --recursive` to complete. If cloning ESP-IDF from GitHub, this step is not needed.

 ## Finding a Project
 
@@ -55,63 +25,92 @@ To start your own project based on an example, copy the example project director
 
 See the Getting Started guide links above for a detailed setup guide. This is a quick reference for common commands when working with ESP-IDF projects:
 
-## Setup Build Environment
-
-(See the Getting Started guide listed above for a full list of required steps with more details.)
-
-* Install host build dependencies mentioned in the Getting Started guide.
-* Run the install script to set up the build environment. The options include `install.bat` or `install.ps1` for Windows, and `install.sh` or `install.fish` for Unix shells.
-* Run the export script on Windows (`export.bat`) or source it on Unix (`source export.sh`) in every shell environment before using ESP-IDF.
-
 ## Configuring the Project
 
-* `idf.py set-target <chip_name>` sets the target of the project to `<chip_name>`. Run `idf.py set-target` without any arguments to see a list of supported targets.
-* `idf.py menuconfig` opens a text-based configuration menu where you can configure the project.
+`make menuconfig`
+
+* Opens a text-based configuration menu for the project.
+* Use up & down arrow keys to navigate the menu.
+* Use Enter key to go into a submenu, Escape key to go out or to exit.
+* Type `?` to see a help screen. Enter key exits the help screen.
+* Use Space key, or `Y` and `N` keys to enable (Yes) and disable (No) configuration items with checkboxes "`[*]`"
+* Pressing `?` while highlighting a configuration item displays help about that item.
+* Type `/` to search the configuration items.
+
+Once done configuring, press Escape multiple times to exit and say "Yes" to save the new configuration when prompted.
 
 ## Compiling the Project
 
-`idf.py build`
+`make -j4 all`
 
 ... will compile app, bootloader and generate a partition table based on the config.
 
+NOTE: The `-j4` option causes `make` to run 4 parallel jobs. This is much faster than the default single job. The recommended number to pass to this option is `-j(number of CPUs + 1)`.
+
 ## Flashing the Project
 
 When the build finishes, it will print a command line to use esptool.py to flash the chip. However you can also do this automatically by running:
 
-`idf.py -p PORT flash`
+`make -j4 flash`
 
-Replace PORT with the name of your serial port (like `COM3` on Windows, `/dev/ttyUSB0` on Linux, or `/dev/cu.usbserial-X` on MacOS. If the `-p` option is left out, `idf.py flash` will try to flash the first available serial port.
+This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with `make menuconfig`.
 
-This will flash the entire project (app, bootloader and partition table) to a new chip. The settings for serial port flashing can be configured with `idf.py menuconfig`.

+You don't need to run `make all` before running `make flash`, `make flash` will automatically rebuild anything which needs it.
 
 ## Viewing Serial Output
 
-The `idf.py monitor` target uses the [idf_monitor tool](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html) to display serial output from Espressif SoCs. idf_monitor also has a range of features to decode crash output and interact with the device. [Check the documentation page for details](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
+The `make monitor` target uses the [idf_monitor tool](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html) to display serial output from the ESP32. idf_monitor also has a range of features to decode crash output and interact with the device. [Check the documentation page for details](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
 
 Exit the monitor by typing Ctrl-].
 
 To build, flash and monitor output in one pass, you can run:
 
-`idf.py flash monitor`
+`make -j4 flash monitor`
 
 ## Compiling & Flashing Only the App
 
 After the initial flash, you may just want to build and flash just your app, not the bootloader and partition table:
 
-* `idf.py app` - build just the app.
-* `idf.py app-flash` - flash just the app.
+* `make app` - build just the app.
+* `make app-flash` - flash just the app.
 
-`idf.py app-flash` will automatically rebuild the app if any source files have changed.
+`make app-flash` will automatically rebuild the app if any source files have changed.
 
 (In normal development there's no downside to reflashing the bootloader and partition table each time, if they haven't changed.)
 
+## Parallel Builds
+
+ESP-IDF supports compiling multiple files in parallel, so all of the above commands can be run as `make -jN` where `N` is the number of parallel make processes to run (generally N should be equal to the number of CPU cores in your system, plus one.)
+
+Multiple make functions can be combined into one. For example: to build the app & bootloader using 5 jobs in parallel, then flash everything, and then display serial output from the ESP32 run:
+
+```
+make -j5 flash monitor
+```
+
+
+## The Partition Table
+
+Once you've compiled your project, the "build" directory will contain a binary file with a name like "my_app.bin". This is an ESP32 image binary that can be loaded by the bootloader.
+
+A single ESP32's flash can contain multiple apps, as well as many different kinds of data (calibration data, filesystems, parameter storage, etc). For this reason a partition table is flashed to offset 0x8000 in the flash.
+
+Each entry in the partition table has a name (label), type (app, data, or something else), subtype and the offset in flash where the partition is loaded.
+
+The simplest way to use the partition table is to `make menuconfig` and choose one of the simple predefined partition tables:
+
+* "Single factory app, no OTA"
+* "Factory app, two OTA definitions"
+
+In both cases the factory app is flashed at offset 0x10000. If you `make partition_table` then it will print a summary of the partition table.
+
+For more details about partition tables and how to create custom variations, view the [`docs/en/api-guides/partition-tables.rst`](docs/en/api-guides/partition-tables.rst) file.
+
 ## Erasing Flash
 
-The `idf.py flash` target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run `idf.py erase-flash`.
+The `make flash` target does not erase the entire flash contents. However it is sometimes useful to set the device back to a totally erased state, particularly when making partition table changes or OTA app updates. To erase the entire flash, run `make erase_flash`.

-
-**注意：** 不同系列芯片和不同 ESP-IDF 版本都有其对应的文档。请参阅[版本](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/versions.html)部分，获得关于如何查找文档以及如何检出 ESP-IDF 的特定发行版的详细信息。
-
-### 非 GitHub 分叉的 ESP-IDF 项目
-
-ESP-IDF 中的子模块采用相对路径（[详见 .gitmodules 文件](.gitmodules)），所以它们会指向 GitHub。 如果 ESP-IDF 被分叉到的仓库不在 GitHub 上，那么你需要在克隆结束后运行该脚本 [tools/set-submodules-to-github.sh](tools/set-submodules-to-github.sh)。
-
-这个脚本会为所有的子模块设置绝对路径，接着可以通过 `git submodule update --init --recursive` 完成子模块的更新。如果 ESP-IDF 是从 GitHub 上克隆得到，则不需要此步骤。
-
-## 寻找项目
-
-除了入门指南中提到的 [esp-idf 模板项目](https://github.com/espressif/esp-idf-template)，ESP-IDF 的 [examples](examples) 目录下还带有很多其它示例项目。
-
-一旦找到了需要的项目，便可以进入该目录，执行配置和构建操作。
-
-如果要基于示例工程开始你自己的项目，请将示例工程复制到 ESP-IDF 目录之外。
-
-# 快速参考
-
-详细的使用方法请参考上面入门指南的链接，这里仅仅列举一些 ESP-IDF 项目开发中常用的命令：
-
-## 设置构建环境
-
-请参考入门指南中列出的详细步骤。
-
-* 在主机中安装入门指南中提到的构建所依赖的工具。
-* 运行安装脚本来设置构建环境。可为 Windows shell 选择 `install.bat` 或 `install.ps1`，为 Unix shell 选择 `install.sh` 和 `install.fish`。
-* 在使用 ESP-IDF 之前，需要在 shell 中运行导出脚本。Windows 下可运行 `export.bat`，Unix 下可运行 `source export.sh`。
-
-## 配置项目
-
-* `idf.py set-target <chip_name>` 可将项目的目标芯片设置为 `<chip_name>`。运行 `idf.py set-target`，不用带任何参数，可查看所有支持的目标芯片列表。
-* `idf.py menuconfig` 可打开一个基于文本的配置菜单，可以用来对项目进行配置。
-
-## 编译项目
-
-`idf.py build`
-
-编译应用程序，引导程序，并根据配置生成分区表。
-
-## 烧写项目
-
-当构建结束，终端会打印出一条命令行，告知如何使用 esptool.py 工具烧写项目到芯片中。但你也可以运行下面这条命令来自动烧写：
-
-`idf.py -p PORT flash`
-
-将其中的 PORT 替换为系统中实际串口的名字（比如 Windows 下的 `COM3`，Linux 下的 `/dev/ttyUSB0`，或者 macOS 下的 `/dev/cu.usbserial-X`。如果省略 `-p` 选项，`idf.py flash` 会尝试使用第一个可用的串口进行烧写。
-
-这会烧写整个项目（包括应用程序，引导程序和分区表）到芯片中，此外还可以使用 `idf.py menuconfig` 来调整串口烧写相关的配置。
-
-不必先运行 `idf.py build` 再运行 `idf.py flash`，`idf.py flash` 会根据需要自动重新构建项目。
-
-## 观察串口输入
-
-`idf.py monitor` 会调用 [idf_monitor 工具](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html)来显示乐鑫芯片的串口输出。`idf_monitor` 还包含一系列的功能来解析程序崩溃后的输出结果并与设备进行交互。更多详细内容，请参阅[文档](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
-
-输入 `Ctrl-]` 可退出监视器。
-
-想要一次性执行构建、烧写和监视，可以运行如下命令：
-
-`idf.py flash monitor`
-
-## 仅编译并烧写应用程序
-
-在第一次烧写过后，你可能只想构建并烧写你的应用程序，不包括引导程序和分区表：
-
-* `idf.py app` - 仅构建应用程序。
-* `idf.py app-flash` - 仅烧写应用程序。
-
-`idf.py app-flash` 会自动判断是否有源文件发生了改变然后重新构建应用程序。
-
-（在正常的开发中，即使引导程序和分区表没有发生变化，每次都重新烧写它们并不会带来什么危害。）
-
-## 擦除 Flash
-
-`idf.py flash` 并不会擦除 flash 上所有的内容，但是有时候我们需要设备恢复到完全擦除的状态，尤其是分区表发生了变化或者 OTA 应用升级时。要擦除整块 flash 请运行 `idf.py erase-flash`。
-
-这条命令还可以和其余命令整合在一起，`idf.py -p PORT erase-flash flash` 会擦除一切然后重新烧写新的应用程序、引导程序和分区表。
-
-# 其它参考资源
-
-* 最新版的文档：https://docs.espressif.com/projects/esp-idf/ ，该文档是由本仓库 [docs 目录](docs) 构建得到。
-
-* 可以前往 [esp32.com 论坛](https://esp32.com/) 提问，挖掘社区资源。

-The latest support policy for ESP-IDF can be found at [https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md](https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY.md)
-
-Support Period Policy
-=====================
-
-* [中文版](./SUPPORT_POLICY_CN.md)
-
-Each ESP-IDF major and minor release (V4.1, V4.2, etc) is supported for 30 months after the initial stable release date.
-
-Supported means that the ESP-IDF team will continue to apply bug fixes, security fixes, etc to the release branch on GitHub, and periodically make new bugfix releases as needed.
-
-Support period is divided into "Service" and "Maintenance" period:
-
-| Period      | Duration     | Recommended for new projects?         |
-| -------     | ------------ | ------------------------------------- |
-| Service     | 12 months    | Yes                                   |
-| Maintenance | 18 months    | No                                    |
-
-During the Service period, bugfixes releases are more frequent. In some cases, support for new features may be added during the Service period (this is reserved for features which are needed to meet particular regulatory requirements or standards for new products, and which carry a very low risk of introducing regressions.)
-
-During the Maintenance period, the version is still supported but only bugfixes for high severity issues or security issues will be applied.
-
-Using an “In Service” version is recommended when starting a new project.
-
-Users are encouraged to upgrade all projects to a newer ESP-IDF release before the support period finishes and the release becomes End of Life (EOL). It is our policy to not continue fixing bugs in End of Life releases.
-
-Pre-release versions (betas, previews, `-rc` and `-dev` versions, etc) are not covered by any support period. Sometimes a particular feature is marked as "Preview" in a release, which means it is also not covered by the support period.
-
-ESP-IDF should be used in an up-to-date software environment. The operating system and other third-party tools should be supported by their maintainers. ESP-IDF cannot keep compatibility with unsupported third-party tools.
-
-The ESP-IDF Programming Guide has information about the [different versions of ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/versions.html) (major, minor, bugfix, etc).
-
-Example
--------
-
-ESP-IDF V3.3 was released in September 2019. It was supported for 30 months until February 2022.
-
-- The first V3.3 release was `v3.3` in September 2019.
-- The ESP-IDF team continues to backport bug fixes, security fixes, etc to the release branch `release/v3.3`.
-- Periodically stable bugfix releases are created from the release branch. For example `v3.3.1`, `v3.3.2`, etc. Users are encouraged to always update to the latest bugfix release.
-- V3.3 bugfix releases continue until February 2022, when all V3.3.x releases become End of Life.
-
-Existing Releases
------------------
-
-ESP-IDF release V4.1 and all newer releases will follow this support period policy. The support period for each release will be announced when the release is made.
-
-For releases made before the current support period policy was announced, the original support periods apply:
-
-* ESP-IDF V4.0.x will be supported until October 2021
-* ESP-IDF V3.3.x will be supported until February 2022
-* ESP-IDF versions before V3.3 are already End of Life.
-
-Policy History
---------------
-
-* September 2019. This policy splits ESP-IDF releases into Standard and Long Term Support.
-* July 2020. All releases from now will have the same support period, which is equal to the previous Long Term Support period. Added “In Service” period, during which versions will receive more updates.

-
-支持期限政策
-=====================
-
-* [英文版](./SUPPORT_POLICY.md)
-
-ESP-IDF 的每个主要版本和次要版本（如 V4.1、V4.2 等）自其首次稳定版本发布之日起将支持 30 个月。
-
-支持意味着 ESP-IDF 团队将会对 GitHub 上的发布分支继续进行 bug 修复、安全修补等，并根据需求定期发布新的 bugfix 版本。
-
-支持周期包括“服务周期“和“维护周期”：
-
-| 周期      | 期限     | 是否建议新项目使用？         |
-| -------     | ------------ | ------------------------------------- |
-| 服务周期     | 12 个月    | 是                                   |
-| 维护周期 | 18 个月    | 否                                    |
-
-在版本的服务周期内，bug 修复版本会较为频繁发布。某些情况下，版本在其服务周期内可能会增加对新功能的支持（这仅适用于需要达到新产品特定规管标准或要求的功能，并且引入新问题的风险极低。）
-
-在版本的维护周期内，版本仍然会继续支持，但仅会对严重问题或安全问题进行 bug 修复。
-
-建议在开始新项目的时候使用处于服务周期的版本。
-
-在某一版本支持期限结束，停止更新维护 (EOL) 前，建议用户升级所有项目至较新的 ESP-IDF 版本。根据《支持期限政策》，我们将停止对 EOL 版本进行 bug 修复。
-
-《支持期限政策》不适用于预发布版本（包括 beta、preview、-rc 和 -dev 版本等）。有时，在发布的版本中存在被标记为 "Preview" 的特定功能，则该功能也不在支持期限内。
-
-请确保在最新的软件环境中使用 ESP-IDF。操作系统和其他第三方工具应得到其维护者的支持。ESP-IDF 无法兼容不受支持的第三方工具。
-
-有关 [ESP-IDF 不同版本](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/versions.html)（主要版本、次要版本、bugfix 版本等）信息，可参阅《ESP-IDF 编程指南》。
-
-示例
--------
-
-ESP-IDF V3.3 于 2019 年 9 月发布，将支持 30 个月至 2022 年 2 月停止。
-
-- V3.3 的首个发布版本为 2019 年 9 月发布的 v3.3。
-- ESP-IDF 团队将持续进行 bug 修复、安全修补等更新，并 backport 至分支 release/v3.3。
-- 定期从 release 分支创建稳定的 bugfix 版本，比如，v3.3.1、v3.3.2 等，并建议用户保持使用最新的 bugfix 版本。
-- V3.3 的 bugfix 版本发布将持续至 2022 年 2 月，届时所有 V3.3.x 将停止更新维护。
-
-现有版本
------------------
-
-ESP-IDF V4.1 及所有后续更新版本都将遵守该《支持期限政策》。每一版本发布时将同时公布其支持期限。
-
-对于该政策公布之日前发布的版本，应适用下述支持期限：
-
-* ESP-IDF V4.0.x 将支持至 2021 年 10 月。
-* ESP-IDF V3.3.x 将支持至 2022 年 2 月。
-* ESP-IDF v3.3 之前的版本已经停止支持。
-
-政策历史
---------------
-
-* 2019 年 9 月。该政策将 ESP-IDF 版本发布分为标准支持版本和长期支持版本。
-* 2020 年 7 月。从现在开始，所有发布的版本都将有相同的支持周期，即之前的长期支持周期。新增了”服务周期“，期间版本的更新将较为频繁。

-# Core Components
-
-## Overview
-
-This document contains details about what the core components are, what they contain, and how they are organized.
-
-## Organization
-
-The core components are organized into two groups.
-
-The first group (referred to as `G0` from now on) contains `hal`, `xtensa` and `riscv` (referred to as `arch` components from now on), `esp_rom`, `esp_common`, and `soc`. This
-group contain information about and low-level access to underlying hardware; or in the case of `esp_common`, hardware-agnostic code and utilities.
-These components can depend on each other, but as much as possible have no dependencies outside the group. The reason for this is that, due to the
-nature of what these components contain, the likelihood is high that a lot of other components will require these. Ideally, then, the dependency
-relationship only goes one way. This makes it easier for these components, as a group, to be usable in another project. One can conceivably implement
-a competing SDK to ESP-IDF on top of these components.
-
-The second group (referred to as `G1` from now on) sits at a higher level than the first group. This group contains the components `esp_hw_support`, `esp_system`, `newlib`, `spi_flash`,
-`freertos`, `log`, and `heap`. Like the first group, circular dependencies within the group are allowed; and being at a higher level, dependency on the first group
-is allowed. These components represent software mechanisms essential to building other components.
-
-## Descriptions
-
-The following is a short description of the components mentioned above.
-
-### `G0` Components
-
-#### `hal`
-
-Contains the hardware abstraction layer and low-level operation implementations for the various peripherals. The low-level functions assign meaningful names to register-level manipulations; the hardware abstraction provide operations one level above this, grouping these low-level functions
-into routines that achieve a meaningful action or state of the peripheral.
-
-Example:
-
-- `spi_flash_ll_set_address` is a low-level function part of the hardware abstraction `spi_flash_hal_read_block`
-
-#### `arch`
-
-Contains low-level architecture operations and definitions, including those for customizations (can be thought of on the same level as the low-level functions of `hal`).
-This can also contain files provided by the architecture vendor.
-
-Example:
-
-- `xt_set_exception_handler`
-- `rv_utils_intr_enable`
-- `ERI_PERFMON_MAX`
-
-#### `esp_common`
-
-Contains hardware-agnostic definitions, constants, macros, utilities, 'pure' and/or algorithmic functions that is useable by all other components (that is, barring there being a more appropriate component to put them in).
-
-Example:
-
-- `BIT(nr)` and other bit manipulation utilities in the future
-- `IDF_DEPRECATED(REASON)`
-- `ESP_IDF_VERSION_MAJOR`
-
-#### `soc`
-
-Contains description of the underlying hardware: register structure, addresses, pins, capabilities, etc.
-
-Example:
-
-- `DR_REG_DPORT_BASE`
-- `SOC_MCPWM_SUPPORTED`
-- `uart_dev_s`
-
-#### `esp_rom`
-
-Contains headers, linker scripts, abstraction layer, patches, and other related files to ROM functions.
-
-Example:
-
-- `esp32.rom.eco3.ld`
-- `rom/aes.h`
-
-### `G1` Components
-
-#### `spi_flash`
-
-SPI flash device access implementation.
-
-#### `freertos`
-
-FreeRTOS port to targets supported by ESP-IDF.
-
-#### `log`
-
-Logging library.
-
-#### `heap`
-
-Heap implementation.
-
-#### `newlib`
-
-Some functions n the standard library are implemented here, especially those needing other `G1` components.
-
-Example:
-
-- `malloc` is implemented in terms of the component `heap`'s functions
-- `gettimeofday` is implemented in terms of system time in `esp_system`
-
-#### `esp_system`
-
-Contains implementation of system services and controls system behavior. The implementations
-here may take hardware resources and/or decide on a hardware state needed for support of a system service/feature/mechanism.
-Currently, this encompasses the following, but not limited to:
-
-- Startup and initialization
-- Panic and debug
-- Reset and reset reason
-- Task and interrupt watchdogs
-
-#### `esp_hw_support`
-
-Contains implementations that provide hardware operations, arbitration, or resource sharing, especially those that
-is used in the system. Unlike `esp_system`, implementations here do not decide on a hardware state or takes hardware resource, acting
-merely as facilitator to hardware access. Currently, this encompasses the following, but not limited to:
-
-- Interrupt allocation
-- Sleep functions
-- Memory functions (external SPIRAM, async memory, etc.)
-- Clock and clock control
-- Random generation
-- CPU utilities
-- MAC settings
-
-### `esp_hw_support` vs `esp_system`
-
-This section details list some implementations and the reason for placing it in either `esp_hw_support` or `esp_system`.
-
-#### `task_wdt.c` (`esp_system`) vs  `intr_alloc.c` (`esp_hw_support`)
-
-The task watchdog fits the definition of taking and configuring hardware resources (wdt, interrupt) for implementation of a system service/mechanism.
-
-This is in contrast with interrupt allocation that merely facilitates access to the underlying hardware for other implementations -
-drivers, user code, and even the task watchdog mentioned previously!
-
-#### `crosscore_int.c` (`esp_system`)
-
-The current implementation of crosscore interrupts is tightly coupled with a number of interrupt reasons
-associated with system services/mechanisms: REASON_YIELD (scheduler), REASON_FREQ_SWITCH (power management)
-REASON_PRINT_BACKTRACE (panic and debug).
-
-However, if an implementation exists that makes it possible to register an arbitrary interrupt reason - a
-lower level inter-processor call if you will, then this implementation is a good candidate for `esp_hw_support`.
-The current implementation in `esp_system` can then just register the interrupt reasons mentioned above.
-
-#### `esp_mac.h`, `esp_chip_info.h`, `esp_random.h` (`esp_hw_support`)
-
-The functions in these headers used to be in `esp_system.h`, but have been split-off.
-
-The remaining functions in `esp_system.h` are those that deal with system behavior, such
-as `esp_register_shutdown_handler`, or are proxy for other system components's APIs such as
-`esp_get_free_heap_size`.
-
-The functions split-off from `esp_system.h` are much more hardware manipulation oriented such as:
-`esp_read_mac`, `esp_random` and `esp_chip_info`.

-// How It Works
-// ************
-
-// 1. Components Overview
-// ======================
-
-// Xtensa has useful feature: TRAX debug module. It allows recording program execution flow at run-time without disturbing CPU.
-// Exectution flow data are written to configurable Trace RAM block. Besides accessing Trace RAM itself TRAX module also allows to read/write
-// trace memory via its registers by means of JTAG, APB or ERI transactions.
-// ESP32 has two Xtensa cores with separate TRAX modules on them and provides two special memory regions to be used as trace memory.
-// Chip allows muxing access to those trace memory blocks in such a way that while one block is accessed by CPUs another one can be accessed by host
-// by means of reading/writing TRAX registers via JTAG. Blocks muxing is configurable at run-time and allows switching trace memory blocks between
-// accessors in round-robin fashion so they can read/write separate memory blocks without disturbing each other.
-// This module implements application tracing feature based on above mechanisms. It allows to transfer arbitrary user data to/from
-// host via JTAG with minimal impact on system performance. This module is implied to be used in the following tracing scheme.
-
-//                                                        ------>------                                         ----- (host components) -----
-//                                                        |           |                                         |                           |

-
-// In general tracing goes in the following way. User application requests tracing module to send some data by calling esp_apptrace_buffer_get(),
-// module allocates necessary buffer in current input trace block. Then user fills received buffer with data and calls esp_apptrace_buffer_put().
-// When current input trace block is filled with app data it is exposed to host and the second block becomes input one and buffer filling restarts.
-// While target application fills one TRAX block host reads another one via JTAG.
-// This module also allows communication in the opposite direction: from host to target. As it was said ESP32 and host can access different TRAX blocks
-// simultaneously, so while target writes trace data to one block host can write its own data (e.g. tracing commands) to another one then when
-// blocks are switched host receives trace data and target receives data written by host application. Target user application can read host data
-// by calling esp_apptrace_read() API.
-// To control buffer switching and for other communication purposes this implementation uses some TRAX registers. It is safe since HW TRAX tracing
-// can not be used along with application tracing feature so these registers are freely readable/writeable via JTAG from host and via ERI from ESP32 cores.
-// Overhead of this implementation on target CPU is produced only by allocating/managing buffers and copying of data.
-// On the host side special OpenOCD command must be used to read trace data.
-
-// 2. TRAX Registers layout
-// ========================
-
-// This module uses two TRAX HW registers to communicate with host SW (OpenOCD).
-//  - Control register uses TRAX_DELAYCNT as storage. Only lower 24 bits of TRAX_DELAYCNT are writable. Control register has the following bitfields:
-//   | 31..XXXXXX..24 | 23 .(host_connect). 23| 22..(block_id)..15 | 14..(block_len)..0 |
-//    14..0  bits - actual length of user data in trace memory block. Target updates it every time it fills memory block and exposes it to host.
-//                  Host writes zero to this field when it finishes reading exposed block;
-//    21..15 bits - trace memory block transfer ID. Block counter. It can overflow. Updated by target, host should not modify it. Actually can be 2 bits;
-//    22     bit  - 'host data present' flag. If set to one there is data from host, otherwise - no host data;
-//    23     bit  - 'host connected' flag. If zero then host is not connected and tracing module works in post-mortem mode, otherwise in streaming mode;
-// - Status register uses TRAX_TRIGGERPC as storage. If this register is not zero then current CPU is changing TRAX registers and
-//   this register holds address of the instruction which application will execute when it finishes with those registers modifications.
-//   See 'Targets Connection' setion for details.
-
-// 3. Modes of operation
-// =====================
-
-// This module supports two modes of operation:
-//  - Post-mortem mode. This is the default mode. In this mode application tracing module does not check whether host has read all the data from block
-//    exposed to it and switches block in any case. The mode does not need host interaction for operation and so can be useful when only the latest
-//    trace data are necessary, e.g. for analyzing crashes. On panic the latest data from current input block are exposed to host and host can read them.
-//    It can happen that system panic occurs when there are very small amount of data which are not exposed to host yet (e.g. crash just after the
-//    TRAX block switch). In this case the previous 16KB of collected data will be dropped and host will see the latest, but very small piece of trace.
-//    It can be insufficient to diagnose the problem. To avoid such situations there is menuconfig option
-//    CONFIG_APPTRACE_POSTMORTEM_FLUSH_THRESH
-//    which controls the threshold for flushing data in case of panic.
-//  - Streaming mode. Tracing module enters this mode when host connects to target and sets respective bits in control registers (per core).
-//    In this mode before switching the block tracing module waits for the host to read all the data from the previously exposed block.
-//    On panic tracing module also waits (timeout is configured via menuconfig via CONFIG_APPTRACE_ONPANIC_HOST_FLUSH_TMO) for the host to read all data.
-
-// 4. Communication Protocol
-// =========================
-
-// 4.1 Trace Memory Blocks
-// -----------------------
-
-// Communication is controlled via special register. Host periodically polls control register on each core to find out if there are any data available.
-// When current input memory block is filled it is exposed to host and 'block_len' and 'block_id' fields are updated in the control register.
-// Host reads new register value and according to it's value starts reading data from exposed block. Meanwhile target starts filling another trace block.
-// When host finishes reading the block it clears 'block_len' field in control register indicating to the target that it is ready to accept the next one.
-// If the host has some data to transfer to the target it writes them to trace memory block before clearing 'block_len' field. Then it sets
-// 'host_data_present' bit and clears 'block_len' field in control register. Upon every block switch target checks 'host_data_present' bit and if it is set
-// reads them to down buffer before writing any trace data to switched TRAX block.
-
-// 4.2 User Data Chunks Level
-// --------------------------
-
-// Since trace memory block is shared between user data chunks and data copying is performed on behalf of the API user (in its normal context) in
-// multithreading environment it can happen that task/ISR which copies data is preempted by another high prio task/ISR. So it is possible situation
-// that task/ISR will fail to complete filling its data chunk before the whole trace block is exposed to the host. To handle such conditions tracing
-// module prepends all user data chunks with header which contains allocated buffer size and actual data length within it. OpenOCD command
-// which reads application traces reports error when it reads incomplete user data block.
-// Data which are transffered from host to target are also prepended with a header. Down channel data header is simple and consists of one two bytes field
-// containing length of host data following the header.
-
-// 4.3 Data Buffering
-// ------------------
-
-// It takes some time for the host to read TRAX memory block via JTAG. In streaming mode it can happen that target has filled its TRAX block, but host
-// has not completed reading of the previous one yet. So in this case time critical tracing calls (which can not be delayed for too long time due to
-// the lack of free memory in TRAX block) can be dropped. To avoid such scenarios tracing module implements data buffering. Buffered data will be sent
-// to the host later when TRAX block switch occurs. The maximum size of the buffered data is controlled by menuconfig option
-// CONFIG_APPTRACE_PENDING_DATA_SIZE_MAX.
-
-// 4.4 Target Connection/Disconnection
-// -----------------------------------
-
-// When host is going to start tracing in streaming mode it needs to put both ESP32 cores into initial state when 'host connected' bit is set
-// on both cores. To accomplish this host halts both cores and sets this bit in TRAX registers. But target code can be halted in state when it has read control
-// register but has not updated its value. To handle such situations target code indicates to the host that it is updating control register by writing
-// non-zero value to status register. Actually it writes address of the instruction which it will execute when it finishes with
-// the registers update. When target is halted during control register update host sets breakpoint at the address from status register and resumes CPU.
-// After target code finishes with register update it is halted on breakpoint, host detects it and safely sets 'host connected' bit. When both cores
-// are set up they are resumed. Tracing starts without further intrusion into CPUs work.
-// When host is going to stop tracing in streaming mode it needs to disconnect targets. Disconnection process is done using the same algorithm
-// as for connecting, but 'host connected' bits are cleared on ESP32 cores.
-
-// 5. Module Access Synchronization
-// ================================
-
-// Access to internal module's data is synchronized with custom mutex. Mutex is a wrapper for portMUX_TYPE and uses almost the same sync mechanism as in
-// vPortCPUAcquireMutex/vPortCPUReleaseMutex. The mechanism uses S32C1I Xtensa instruction to implement exclusive access to module's data from tasks and
-// ISRs running on both cores. Also custom mutex allows specifying timeout for locking operation. Locking routine checks underlaying mutex in cycle until
-// it gets its ownership or timeout expires. The differences of application tracing module's mutex implementation from vPortCPUAcquireMutex/vPortCPUReleaseMutex are:
-// - Support for timeouts.
-// - Local IRQs for CPU which owns the mutex are disabled till the call to unlocking routine. This is made to avoid possible task's prio inversion.
-//   When low prio task takes mutex and enables local IRQs gets preempted by high prio task which in its turn can try to acquire mutex using infinite timeout.
-//   So no local task switch occurs when mutex is locked. But this does not apply to tasks on another CPU.
-//   WARNING: Priority inversion can happen when low prio task works on one CPU and medium and high prio tasks work on another.
-// WARNING: Care must be taken when selecting timeout values for trace calls from ISRs. Tracing module does not care about watchdogs when waiting
-// on internal locks and for host to complete previous block reading, so if timeout value exceeds watchdog's one it can lead to the system reboot.
-
-// 6. Timeouts
-// ===========
-
-// Timeout mechanism is based on xthal_get_ccount() routine and supports timeout values in microseconds.
-// There are two situations when task/ISR can be delayed by tracing API call. Timeout mechanism takes into account both conditions:
-// - Trace data are locked by another task/ISR. When wating on trace data lock.
-// - Current TRAX memory input block is full when working in streaming mode (host is connected). When waiting for host to complete previous block reading.
-// When wating for any of above conditions xthal_get_ccount() is called periodically to calculate time elapsed from trace API routine entry. When elapsed
-// time exceeds specified timeout value operation is canceled and ESP_ERR_TIMEOUT code is returned.
