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.
|
|
|
|
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.
|
|
|
|
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.
|
|
|
|
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.
