-# Compatibility Between ESP-IDF Releases and Revisions of Espressif SoCs
-
-* [中文版](./COMPATIBILITY_CN.md)
-
-Espressif keeps improving the performance of its SoCs by providing new chip revisions. However, some of the improvements require special software support. Some of the software supports are even mandatory for the chip revisions to run normally.
-
-This document describes the compatibility between ESP-IDF releases and Espressif SoC revisions.
-
-NOTE: This document on release branches may be out-of-date. Check the [Compatibility file on master](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY.md) for the most accurate information.
-
-See [Compatibility Advisory for Chip Revision Numbering Scheme](https://www.espressif.com/sites/default/files/advisory_downloads/AR2022-005%20Compatibility%20Advisory%20for%20Chip%20Revision%20Numbering%20%20Scheme.pdf) on the versioning of Espressif SoC revisions.
-
-You can run `esptool chip-id` to detect the series and revision of an SoC. See [SoC Errata](https://www.espressif.com/en/support/documents/technical-documents?keys=errata) for more on how to distinguish between chip revisions, and the improvements provided by chip revisions. And run `idf.py --version` to know the version of current ESP-IDF.
-
-## ESP-IDF Support for Different Chip Revisions
-
-The sections below show the requirements to ESP-IDF version of chip revisions. Each chip revision corresponds to specific `Recommended` and `Required` versions of ESP-IDF:
-
- `Recommended`: shows from which version of ESP-IDF you can make use of all the improvements of the chip revision. Running binary compiled with ESP-IDF below the `Recommended` version of a chip revision, software may not benefit from the bugfix/features provided by the chip revision. The chip will have almost the same behavior as its previous revision.
-
- `Required`: shows the minimum version required to run the chip revision normally. Running binary compiled below the `Required` version, the binary may have unpredictable behavior.
-
-Though the software can make use of all the features of a chip revision, if its version is higher than the `Recommended` version of the chip, it is still recommended to use the latest bugfix version of the release branch. The latest bugfix version fixes a number of issues and helps improve product stability.
-
-For example, if we have a chip, whose `Required`/`Recommended` version of `release/v5.1` branch is `v5.1.2`/`v5.1.4`, and the latest release on that branch is `v5.1.6`. Then the chip will not boot up with ESP-IDF `v5.1`-`v5.1.1` or will have unpredictable behavior, and application may not make use of all benefits of the chip, when running with ESP-IDF `v5.1.2` or `v5.1.3`. Though `v5.1.4` well supports the chip revision, it is still recommended to upgrade ESP-IDF to `v5.1.6`.

-## What If the ESP-IDF Version Is Lower than the `Required` Version?
-
-Latest ESP-IDF versions can prevent from downloading to, or even execute binaries on unsupported chips. ESP-IDF of versions v4.4.5+, v5.0.1+, v5.1 and above have both esptool download check and bootloader loading check against the chip revision. While ESP-IDF v4.3.5 has only esptool downloading check.
-
-For earlier ESP-IDF versions without such checking, which is incompatible with the given chip revision, the chips running such versions will have unpredictable behavior.

-# ESP-IDF 版本与乐鑫芯片版本兼容性
-
-* [English Version](./COMPATIBILITY.md)
-
-为不断提高芯片性能，乐鑫会为其芯片发布新版本。但新芯片版本中的某些性能提升依赖特殊的软件支持，有时候新芯片版本必须在一定的软件版本下才能正常运行。
-
-本文档介绍了具体 ESP-IDF 版本与乐鑫芯片版本之间的兼容性情况。
-
-注意：各分支上的兼容性文档可能不是最新版本，请参考 [master 分支上的兼容性文件](https://github.com/espressif/esp-idf/blob/master/COMPATIBILITY_CN.md) 以获取最新信息。
-
-有关乐鑫芯片版本的编码方式，请参考 [关于芯片版本 (Chip Revision) 编码方式的兼容性公告](https://www.espressif.com/sites/default/files/advisory_downloads/AR2022-005%20%E5%85%B3%E4%BA%8E%E8%8A%AF%E7%89%87%E7%89%88%E6%9C%AC%E7%BC%96%E7%A0%81%E6%96%B9%E5%BC%8F%20%28Chip%20Revision%29%20%E7%9A%84%E5%85%BC%E5%AE%B9%E6%80%A7%E5%85%AC%E5%91%8A.pdf)。
-
-运行 `esptool chip-id` 可查看芯片系列及其版本。有关区分芯片版本及版本改进内容的更多信息，请参考 [芯片勘误表](https://www.espressif.com.cn/zh-hans/support/documents/technical-documents?keys=%E5%8B%98%E8%AF%AF%E8%A1%A8)。运行 `idf.py --version` 可查看当前的 ESP-IDF 版本。
-
-## ESP-IDF 对各芯片版本的支持
-
-下文介绍了 ESP-IDF 对各芯片版本的支持情况，每个芯片版本都有对应的 ESP-IDF `推荐版本` 和 `需求版本`：
-
- `推荐版本`：表示从该版本的 ESP-IDF 开始，软件可以利用芯片版本提升的性能。如果在该芯片版本上运行低于 `推荐版本` 的 ESP-IDF 来编译二进制文件，软件可能无法利用该芯片版本修复的错误或新增的功能，芯片行为将与其上一版本几乎相同。
-
- `需求版本`：表示该芯片版本正常运行所需的最低 ESP-IDF 版本。如果在该芯片版本上运行低于 `需求版本` 的 ESP-IDF 来编译二进制文件，可能会出现不可预测的芯片行为。
-
-即便使用的软件版本已高于该芯片版本的对应 `推荐版本`，软件已经能够利用该芯片版本的所有功能，我们仍建议用户升级到该发布分支的最新 bugfix 版本。新的 bugfix 版本修复了一些问题，有助于提升产品稳定性。
-
-例如，对于某一芯片版本，其 `release/v5.1` 分支的 `需求版本` 和 `推荐版本` 分别是 `v5.1.2` 和 `v5.1.4`，而该分支的最新版本是 `v5.1.6`。那么，在使用 ESP-IDF `v5.1` - `v5.1.1` 时，芯片将无法启动，或会出现不可预测的行为，而在使用 ESP-IDF `v5.1.2` 或 `v5.1.3` 时，应用程序可能无法使用芯片的部分性能。此外，虽然 `v5.1.4` 已支持该芯片版本，但仍建议将 ESP-IDF 升级到 `v5.1.6`。

-## 如果 ESP-IDF 版本低于 `需求版本` 会出现什么情况？
-
-使用最新的 ESP-IDF 版本时，软件会阻止下载二进制文件到不支持的芯片版本上，甚至可以防止二进制文件在不支持的芯片版本上被执行。v4.4.5+、v5.0.1+、v5.1 及以上版本的 ESP-IDF 都支持针对芯片版本的 esptool 下载检查和引导加载器加载检查，但 ESP-IDF v4.3.5 只支持 esptool 下载检查。
-
-更早的 ESP-IDF 版本没有此类检查，若与芯片版本不兼容，芯片运行软件时可能会出现不可预测的行为。

+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/en/github/collaborating-with-issues-and-pull-requests/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>`?
+
+* Have you installed the :doc:`pre-commit hook <install-pre-commit-hook>` for esp-idf project?
+
+* 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 <https://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.

+// 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

+
+// 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.

-// 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.

 File    : SEGGER_SYSVIEW_Conf.h
-Purpose : SEGGER SystemView configuration file.
-          Set defines which deviate from the defaults (see SEGGER_SYSVIEW_ConfDefaults.h) here.
-Revision: $Rev: 21292 $
-
-Additional information:
-  Required defines which must be set are:
-    SEGGER_SYSVIEW_GET_TIMESTAMP
-    SEGGER_SYSVIEW_GET_INTERRUPT_ID
-  For known compilers and cores, these might be set to good defaults
-  in SEGGER_SYSVIEW_ConfDefaults.h.
-
-  SystemView needs a (nestable) locking mechanism.
-  If not defined, the RTT locking mechanism is used,
-  which then needs to be properly configured.
+Purpose : SEGGER SystemView configuration.
