+# DangerJS pull request automatic review tool - GitHub
+
+## Implementation
+The main development is done in Espressif Gitlab project.
+Espressif [GitHub project espressif/esp-idf](https://github.com/espressif/esp-idf) is only a public mirror. 
+
+Therefore, all changes and updates to DangerJS files (`.github/dangerjs`) must be made via MR in the **Gitlab** repository by Espressif engineer. 
+
+When adding a new Danger rule or updating existing one, might be a good idea to test it on the developer's fork of GitHub project. This way, the new feature can be tested using a GitHub action without concern of damaging Espressif's GitHub repository.
+
+Danger for Espressif GitHub is implemented in TypeScript. This makes the code more readable and robust than plain JavaScript. 
+Compilation to JavaScript code (using `tsc`) is not necessary; Danger handles TypeScript natively.
+
+A good practice is to store each Danger rule in a separate module, and then import these modules into the main Danger file `.github/dangerjs/dangerfile.ts` (see how this is done for currently present modules when adding a new one).
+
+If the Danger module (new check/rule) uses an external NPM module (e.g. `axios`), be sure to add this dependency to `.github/dangerjs/package.json` and also update `.github/dangerjs/package-lock.json`.
+
+In the GitHub action, `danger` is not installed globally (nor are its dependencies) and the `npx` call is used to start the `danger` checks in CI.
+
+
+## Adding new Danger rule
+For local development you can use following strategy
+
+#### Install dependencies
+```sh
+cd .github/dangerjs
+npm install
+```
+(If the IDE still shows compiler/typing errors, reload the IDE window.)
+
+#### Add new code as needed or make updates
+
+#### Test locally
+Danger rules can be tested locally (without running the GitHub action pipeline). 
+To do this, you have to first export the ENV variables used by Danger in the local terminal:
+
+```sh
+export GITHUB_TOKEN='**************************************'
+```
+
+Then you can call Danger by:
+```sh
+cd .github/dangerjs
+
+danger pr https://github.com/espressif/esp-idf/pull/<number_of_pull_request> 
+```
+The result will be displayed in your terminal.

+
+1. An internal issue has been created for the PR, we assign it to the relevant engineer
+2. They review the PR and either approve it or ask you for changes or clarifications
+3. Once the Github PR is approved, we synchronize it into our internal git repository
+4. In the internal git repository we do the final review, collect approvals from core owners and make sure all the automated tests are passing
+    - At this point we may do some adjustments to the proposed change, or extend it by adding tests or documentation.
+5. If the change is approved and passes the tests it is merged into the \`master\` branch
+6. On next sync from the internal git repository merged change will appear in this public Github repository

 ## Upload/Download Artifacts to Internal Minio Server
 
-Please refer to the documentation [here](https://docs.espressif.com/projects/idf-ci/en/latest/guides/cli.html)
+### Users Without Access to Minio
+
+If you don't have access to the internal Minio server, you can still download the artifacts from the shared link in the job log.
+
+The log will look like this:
+
+```shell
+Pipeline ID    : 587355
+Job name       : build_clang_test_apps_esp32
+Job ID         : 40272275
+Created archive file: 40272275.zip, uploading as 587355/build_dir_without_map_and_elf_files/build_clang_test_apps_esp32/40272275.zip
+Please download the archive file includes build_dir_without_map_and_elf_files from [INTERNAL_URL]
+```
+
+### Users With Access to Minio
+
+#### Env Vars for Minio
+
+Minio takes these env vars to connect to the server:
+
+- `IDF_S3_SERVER`
+- `IDF_S3_ACCESS_KEY`
+- `IDF_S3_SECRET_KEY`
+- `IDF_S3_BUCKET`
+
+#### Artifacts Types and File Patterns
+
+The artifacts types and corresponding file patterns are defined in tools/ci/artifacts_handler.py, inside `ArtifactType` and `TYPE_PATTERNS_DICT`.
+
+#### Upload
+
+```shell
+python tools/ci/artifacts_handler.py upload
+```
+
+ will upload the files that match the file patterns to minio object storage with name:
+
+`<pipeline_id>/<artifact_type>/<job_name>/<job_id>.zip`
+
+For example, job 39043328 will upload these four files:
+
+- `575500/map_and_elf_files/build_pytest_examples_esp32/39043328.zip`
+- `575500/build_dir_without_map_and_elf_files/build_pytest_examples_esp32/39043328.zip`
+- `575500/logs/build_pytest_examples_esp32/39043328.zip`
+- `575500/size_reports/build_pytest_examples_esp32/39043328.zip`
+
+#### Download
+
+You may run
+
+```shell
+python tools/ci/artifacts_handler.py download --pipeline_id <pipeline_id>
+```
+
+to download all files of the pipeline, or
+
+```shell
+python tools/ci/artifacts_handler.py download --pipeline_id <pipeline_id> --job_name <job_name_or_pattern>
+```
+
+to download all files with the specified job name or pattern, or
+
+```shell
+python tools/ci/artifacts_handler.py download --pipeline_id <pipeline_id> --job_name <job_name_or_pattern> --type <artifact_type> <artifact_type> ...
+```
+
+to download all files with the specified job name or pattern and artifact type(s).

 The first group (referred to as `G0`) includes `hal`, `arch` (where `arch` is either `riscv` or `xtensa` depending on the chip), `esp_rom`, `esp_common`, and `soc`. This group contains information about and provides low-level access to the underlying hardware. In the case of `esp_common`, it contains hardware-agnostic code and utilities. These components may have dependencies on each other within the group, but outside dependencies should be minimized. The reason for this approach is that these components are fundamental, and many other components may require them. Ideally, the dependency relationship only goes one way, making it easier for this group to be usable in other projects.

+// 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.
+// Execution 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 and one Performance Monitor register 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' section for details.
+//  - CRC16 register uses ERI_PERFMON_PM1 as storage. This register is used to store CRC16 checksum of the exposed trace memory block.
+//    The register has the following format:
+//    | 31..16 (CRC indicator) | 15..0 (CRC16 value) |
+//    CRC indicator (0xA55A) is used to distinguish valid CRC values from other data that might be in the register.
+//    CRC16 is calculated over the entire exposed block and is updated every time a block is exposed to the host.
+//    This allows the host to verify data integrity of the received trace data.
+
+// 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 underlying 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 waiting 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 waiting 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.

-// 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.
-// Execution 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 and one Performance Monitor register 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' section for details.
-//  - CRC16 register uses ERI_PERFMON_PM1 as storage. This register is used to store CRC16 checksum of the exposed trace memory block.
-//    The register has the following format:
-//    | 31..16 (CRC indicator) | 15..0 (CRC16 value) |
-//    CRC indicator (0xA55A) is used to distinguish valid CRC values from other data that might be in the register.
-//    CRC16 is calculated over the entire exposed block and is updated every time a block is exposed to the host.
-//    This allows the host to verify data integrity of the received trace data.
-
-// 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 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 underlying 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 waiting 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 waiting 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.
