The following two functions in bootloader_support are private now: * esp_secure_boot_verify_sbv2_signature_block() * esp_secure_boot_verify_rsa_signature_block() They have been moved into private header files inside bootloader_private/ * Removed bootloader_reset_reason.h and bootloader_common_get_reset_reason() completely. Alternative in ROM component is available. * made esp_efuse.h independent of target-specific rom header

Migrate System to ESP-IDF 5.0
|
|
==================================
|
|
|
|
Inter-Processor Call
|
|
-----------------------
|
|
|
|
IPC (Inter-Processor Call) component has been moved to ``esp_system``.
|
|
|
|
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.
|
|
|
|
Therefore, If you want to use the function with the prefix ``esp_clk`` please include ``esp_private/esp_clk.h`` instead.
|
|
|
|
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.
|
|
|
|
Bootloader Support
|
|
------------------
|
|
|
|
* 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.
|
|
|
|
Trax
|
|
----
|
|
|
|
The header ``trax.h`` has been made private. ESP-IDF developers should include ``esp_private/trax.h`` instead.
|
|
|
|
ROM
|
|
---
|
|
Deprecated ROM related header files from `components/esp32/rom/` (old include path: `rom/*.h`) have been deleted. Please update to use the new target-specific path from `components/esp_rom/include/{IDF_TARGET_NAME}/` (new include path: `{IDF_TARGET_NAME}/rom/*.h`).
|
|
|
|
ESP HW Support
|
|
--------------
|
|
|
|
- The header files ``soc/cpu.h`` have been deleted and deprecated CPU util functions have been removed. ESP-IDF developers should include ``esp_cpu.h`` instead for equivalent functions.
|
|
- 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"``.
|
|
- ``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.
|
|
- ``esp_spiram_get_chip_size`` and ``esp_spiram_get_size`` have been deleted. You should use ``esp_psram_get_size`` instead.
|
|
|
|
Efuse
|
|
----------
|
|
|
|
The parameter type of function ``esp_secure_boot_read_key_digests()`` changed from ``ets_secure_boot_key_digests_t*`` to ``esp_secure_boot_key_digests_t*``. ``ets_secure_boot_key_digests_t*``. The new type is the same as the old one, except that the ``allow_key_revoke`` flag has been removed. The latter was always set to ``true`` in current code, hence, it didn't provide additional information.
|
|
|
|
ESP Common
|
|
----------
|
|
|
|
- `EXT_RAM_ATTR` is deprecated. Use this new macro `EXT_RAM_BSS_ATTR` to put .bss on PSRAM.
|
|
|
|
ESP System
|
|
----------
|
|
- The header files ``esp_random.h``, ``esp_mac.h`` and ``esp_chip_info.h``, which were all previously indirectly included via the header file ``esp_system.h``, must now be included directly. These headers are removed from ``esp_system.h``.
|
|
- The header file ``eh_frame_parser.h`` must now be included with a ``esp_private`` prefix like ``#include "esp_private/eh_frame_parser.h"``.
|
|
- The header file ``esp_int_wdt.h`` must now be included with a ``esp_private`` prefix like ``#include "esp_private/esp_int_wdt.h"``.
|
|
|
|
SOC dependency
|
|
--------------
|
|
|
|
- Public API headers who are listed in the Doxyfiles won't expose unstable and unnecessary soc header files like ``soc/soc.h``, ``soc/rtc.h``. That means, the user has to explicitly include them in their code if these "missing" header files are still wanted.
|
|
- Kconfig option ``LEGACY_INCLUDE_COMMON_HEADERS`` is also removed.
|
|
- The header file ``soc/soc_memory_types.h`` has been deprecated. Users should use the ``esp_memory_utils.h`` instead. Including `soc/soc_memory_types.h` will bring a build warning like `soc_memory_types.h is deprecated, please migrate to esp_memory_utils.h`
|
|
|
|
APP Trace
|
|
---------
|
|
|
|
One of the timestamp sources has changed from the legacy timer group driver to the new :doc:`GPTimer <../api-reference/peripherals/gptimer>`. Kconfig choices like ``APPTRACE_SV_TS_SOURCE_TIMER00`` has been changed to ``APPTRACE_SV_TS_SOURCE_GPTIMER``. User doesn't need to choose the group and timer ID any more.
|
|
|
|
ESP Timer
|
|
---------
|
|
|
|
Removed the FRC2 based legacy implementation of esp_timer available on ESP32. The simpler and more efficient implementation based on the LAC timer is now the only option.
|
|
|
|
ESP image
|
|
---------
|
|
|
|
Rename the image SPI speed enum definition.
|
|
- Enum ``ESP_IMAGE_SPI_SPEED_80M`` has been renamed to ``ESP_IMAGE_SPI_SPEED_DIV_1``.
|
|
- Enum ``ESP_IMAGE_SPI_SPEED_40M`` has been renamed to ``ESP_IMAGE_SPI_SPEED_DIV_2``.
|
|
- Enum ``ESP_IMAGE_SPI_SPEED_26M`` has been renamed to ``ESP_IMAGE_SPI_SPEED_DIV_3``.
|
|
- Enum ``ESP_IMAGE_SPI_SPEED_20M`` has been renamed to ``ESP_IMAGE_SPI_SPEED_DIV_4``.
|
|
|
|
Task Watchdog Timers
|
|
--------------------
|
|
|
|
- The API for ``esp_task_wdt_init()`` has changed as follows
|
|
|
|
- Configuration is now passed as a configuration structure.
|
|
- The function will now handle subscribing of the idle tasks if configured to do so
|
|
|
|
Efuse
|
|
-----
|
|
|
|
- Added eFuse wafer revisions: major and minor. The `esp_efuse_get_chip_ver()` API is not compatible with these changes this is why it was removed. Please use instead of it the following APIs: `efuse_hal_get_major_chip_version()`, `efuse_hal_get_minor_chip_version()` or `efuse_hal_chip_revision()`.
