Inter-Processor Call
|
||||
-----------------------
|
||||
|
||||
IPC (Inter-Processor Call) component has been moved to ``esp_system``.
|
||||
IPC (Inter-Processor Call) feature is no longer a stand-alone component and has been integrated into the ``esp_system`` component.
|
||||
|
||||
Thus, any project presenting a ``CMakeLists.txt`` file with the parameters ``PRIV_REQUIRES esp_ipc`` or ``REQUIRES esp_ipc``, should be modified to simply remove these options as ``esp_system`` component is included by default.

ESP Clock
|
||||
---------
|
||||
|
||||
The old headers ``{IDF_TARGET_NAME}/clk.h``, ``esp_clk.h`` have been removed.
|
||||
The ESP Clock API (functions/types/macros prefixed with ``esp_clk``) has been made into a private API. Thus, the previous include paths ``#include "{IDF_TARGET_NAME}/clk.h"`` and ``#include "esp_clk.h"`` have been removed. If users still require usage of the ESP Clock API (though this is not recommended), it can be included via ``#include "esp_private/esp_clk.h"``.
|
||||
|
||||
Therefore, If you want to use the function with the prefix ``esp_clk`` please include ``esp_private/esp_clk.h`` instead.
|
||||
.. note::
|
||||
|
||||
Private APIs are not stable and no are longer subject to the ESP-IDF versioning scheme's breaking change rules. Thus, it is not recommended for users to continue calling private APIs in their applications.
|
||||
|
||||
Cache Error Interrupt
|
||||
---------------------
|
||||
|
||||
The old headers ``{IDF_TARGET_NAME}/cache_err_int.h`` have been removed. Please include ``esp_private/cache_err_int.h`` instead.
|
||||
The Cache Error Interrupt API (functions/types/macros prefixed with ``esp_cache_err``) has been made into a private API. Thus, the previous include path ``#include "{IDF_TARGET_NAME}/cache_err_int.h"`` has been removed. If users still require usage of the Cache Error Interrupt API (though this is not recommended), it can be included via ``#include "esp_private/cache_err_int.h"``.

* The function ``bootloader_common_get_reset_reason()`` has been removed. Please use the function ``esp_rom_get_reset_reason()`` in the ROM component.
|
||||
* The functions ``esp_secure_boot_verify_sbv2_signature_block()`` and ``esp_secure_boot_verify_rsa_signature_block()`` have been removed without replacement. We don't expect users to use these directly. If they are indeed still neccessary, please open a feature request on github explaining why these functions are necessary to you.

Brownout
|
||||
--------
|
||||
|
||||
The header ``brownout.h`` has been made private. ESP-IDF developers should include ``esp_private/brownout.h`` instead.
|
||||
The Brownout API (functions/types/macros prefixed with ``esp_brownout``) has been made into a private API. Thus, the previous include path ``#include "brownout.h"`` has been removed. If users still require usage of the Brownout API (though this is not recommended), it can be included via ``#include "esp_private/brownout.h"``.
|

Trax
|
||||
----
|
||||

- ``esp_cpu_get_ccount()``, ``esp_cpu_set_ccount()`` and ``esp_cpu_in_ocd_debug_mode()`` were removed from ``esp_cpu.h``. ESP-IDF developers should use respectively ``esp_cpu_get_cycle_count()``, ``esp_cpu_set_cycle_count()`` and ``esp_cpu_dbgr_is_attached()`` instead.
|

- The header file ``esp_intr.h`` has been deleted. Please include ``esp_intr_alloc.h`` to allocate and manipulate interrupts.
|
||||
- The header file ``esp_panic.h`` has been deleted. ESP-IDF developers should include ``esp_private/panic_reason.h`` to get supported panic reasons. And should include ``esp_debug_helpers.h`` to use any debug related helper functions, e.g. print backtrace.
|
||||
- The header file ``soc_log.h`` is now renamed to ``esp_hw_log.h`` and all logging macros have been updated from ``SOC_LOGx`` to ``ESP_HW_LOGx``. ESP-IDF users must use the later form.
|
||||
- The header files ``spinlock.h``, ``clk_ctrl_os.h`` and ``rtc_wdt.h`` must now be included without the ``soc`` prefix. Eg:- ``#include "spinlock.h"``.

|
||||
- The header files ``spinlock.h``, ``clk_ctrl_os.h``, and ``rtc_wdt.h`` must now be included without the ``soc`` prefix. For example, ``#include "spinlock.h"``.
|
||||
- ``esp_chip_info()`` returns the chip version in the format = 100 * ``major eFuse version`` + ``minor eFuse version``. Thus, the ``revision`` in the ``esp_chip_info_t`` structure is expanded to uint16_t to fit the new format.
|
||||
|
||||
PSRAM
|
||||
^^^^^
|
||||
- The target specific header files ``spiram.h`` have been deleted. The header file ``esp_spiram.h`` has been deleted. A new component ``esp_psram`` is created, you should include ``esp_psram.h`` instead. Besides, you might need to add ``esp_psram`` component to the list of component requirements in CMakeLists.txt.
|

--------------
|

|
||||
-------
|
||||
|
||||
- 函数 ``esp_secure_boot_read_key_digests()`` 的参数类型从 ``ets_secure_boot_key_digests_t*`` 更新为 ``esp_secure_boot_key_digests_t*``。新类型与旧类型相同，仅移除了 ``allow_key_revoke`` 标志。在当前代码中，后者总是被设置为 ``true``，并未提供额外信息。
|
||||
- 针对 eFuse 晶圆增加主要修订版本和次要修订版本。API ``esp_efuse_get_chip_ver()`` 与新修订不兼容，因此已被移除。请使用 API ``efuse_hal_get_major_chip_version()``、``efuse_hal_get_minor_chip_version()`` 或 ``efuse_hal_chip_revision()`` 来代替原有 API。
|
||||
|
||||
esp_common
|
||||
------------
|
||||
``EXT_RAM_ATTR`` 已被弃用。请使用新的宏 ``EXT_RAM_BSS_ATTR`` 以将 .bss 放在 PSRAM 上。
|
||||
|
||||
esp_system
|
||||
------------
|
||||
- 头文件 ``esp_random.h``、``esp_mac.h`` 和 ``esp_chip_info.h`` 以往都是通过头文件 ``esp_system.h`` 间接包含，更新后必须直接包含。已移除从 ``esp_system.h`` 中的间接包含功能。
|
||||
- 回溯解析器 API（即以 ``esp_eh_frame_`` 为前缀的函数、类型或宏）已被更新为私有 API。因此，原先的包含路径 ``#include "eh_frame_parser.h"`` 已被移除。如仍需使用回溯解析器 API（并不推荐），请使用 ``#include "esp_private/eh_frame_parser.h"`` 来包含。
|
||||
- 中断看门狗定时器 API（即以 ``esp_int_wdt_`` 为前缀的函数、类型或宏）已被更新为私有 API。因此，原先的包含路径 ``#include "esp_int_wdt.h"`` 已被移除。如仍需使用中断看门狗定时器 API（并不推荐），请使用 ``#include "esp_private/esp_int_wdt.h"`` 来包含。
|
||||
|
||||
SOC 依赖性
|
||||
--------------
|
||||
|
||||
- Doxyfiles 中列出的公共 API 头文件中不会显示不稳定和非必要的 SOC 头文件，如 ``soc/soc.h`` 和 ``soc/rtc.h``。这意味着，如果用户仍然需要这些“缺失”的头文件，就必须在代码中明确包含这些文件。
|
||||
- Kconfig 选项 ``LEGACY_INCLUDE_COMMON_HEADERS`` 也已被移除。
|
||||
- 头文件 ``soc/soc_memory_types.h`` 已被弃用。请使用 ``esp_memory_utils.h``。包含 ``soc/soc_memory_types.h`` 将触发构建警告，如 ``soc_memory_types.h is deprecated, please migrate to esp_memory_utils.h``。
|
||||
|
||||
应用跟踪
|
||||
--------
|
||||
|
||||
其中一个时间戳源已从定时器组驱动改为新的 :doc:`GPTimer <../../api-reference/peripherals/gptimer>`。Kconfig 选项已重新命名，例如 ``APPTRACE_SV_TS_SOURCE_TIMER00`` 已更改为 ``APPTRACE_SV_TS_SOURCE_GPTIMER``。用户已无需选择组和定时器 ID。
|
||||
|
||||
esp_timer
|
||||
-----------
|
||||
|
||||
基于 FRC2 的 esp_timer 过去可用于 ESP32，现在已被移除，更新后仅可使用更简单有效的 LAC 定时器。
|
||||
|
||||
ESP 镜像
|
||||
---------
|
||||
|
||||
ESP 镜像中关于 SPI 速度的枚举成员已重新更名：
|
||||
|
||||
- ``ESP_IMAGE_SPI_SPEED_80M`` 已被重新命名为 ``ESP_IMAGE_SPI_SPEED_DIV_1``。
|
||||
- ``ESP_IMAGE_SPI_SPEED_40M`` 已被重新命名为 ``ESP_IMAGE_SPI_SPEED_DIV_2``。
|
||||
- ``ESP_IMAGE_SPI_SPEED_26M`` 已被重新命名为 ``ESP_IMAGE_SPI_SPEED_DIV_3``。
|
||||
- ``ESP_IMAGE_SPI_SPEED_20M`` 已被重新命名为 ``ESP_IMAGE_SPI_SPEED_DIV_4``。
|
||||
|
||||
任务看门狗定时器
|
||||
--------------------
|
||||
|
||||
- API ``esp_task_wdt_init()`` 更新后有如下变化：
|
||||
|
||||
- 以结构体的形式传递配置。
|
||||
- 可将该函数配置为订阅空闲任务。
|
||||
|
||||
FreeRTOS
|
||||
--------
|
||||
|
||||
遗留 API 及数据类型
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
在以往版本中，ESP-IDF 默认设置 ``configENABLE_BACKWARD_COMPATIBILITY`` 选项，因此可使用 FreeRTOS v8.0.0 之前的函数名称和数据类型。该选项现在已默认禁用，因此默认情况下不再支持以往的 FreeRTOS 名称或类型。用户可以选择以下一种解决方式：
|
||||
|
||||
- 更新代码，删除以往的 FreeRTOS 名称或类型。
|
||||
- 启用 :ref:`CONFIG_FREERTOS_ENABLE_BACKWARD_COMPATIBILITY` 以显式调用这些名称或类型。
|
||||
|
||||
任务快照
|
||||
^^^^^^^^^^
|
||||
|
||||
头文件 ``task_snapshot.h`` 已从 ``freertos/task.h`` 中移除。如需使用任务快照 API，请包含 ``freertos/task_snapshot.h``。
|
||||
|
||||
函数 :cpp:func:`vTaskGetSnapshot` 现返回 ``BaseType_t``，成功时返回值为 ``pdTRUE``，失败则返回 ``pdFALSE``。
|
||||
|
||||
FreeRTOS 断言
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
在以往版本中，FreeRTOS 断言通过 ``FREERTOS_ASSERT`` kconfig 选项独立配置，不同于系统的其他部分。该选项已被移除，现在需要通过 ``COMPILER_OPTIMIZATION_ASSERTION_LEVEL`` 来完成配置。
|
||||
|
||||
FreeRTOS 移植相关的宏
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
已移除用以保证弃用 API 向后兼容性的 ``portmacro_deprecated.h`` 文件。建议使用下列函数来代替弃用 API。
|
||||
|
||||
- ``portENTER_CRITICAL_NESTED()`` 已被移除，请使用 ``portSET_INTERRUPT_MASK_FROM_ISR()`` 宏。
|
||||
- ``portEXIT_CRITICAL_NESTED()`` 已被移除，请使用 ``portCLEAR_INTERRUPT_MASK_FROM_ISR()`` 宏。
|
||||
- ``vPortCPUInitializeMutex()`` 已被移除，请使用 ``spinlock_initialize()`` 函数。
|
||||
- ``vPortCPUAcquireMutex()`` 已被移除，请使用 ``spinlock_acquire()`` 函数。
|
||||
- ``vPortCPUAcquireMutexTimeout()`` 已被移除，请使用 ``spinlock_acquire()`` 函数。
|
||||
- ``vPortCPUReleaseMutex()`` 已被移除，请使用 ``spinlock_release()`` 函数。
