  1. Migrate System to ESP-IDF 5.0
    2. 

  2. ==================================
    3. 

  3. 

  4. Inter-Processor Call
    5. 

  5. -----------------------
    6. 

  6. 

  7. IPC (Inter-Processor Call) component has been moved to ``esp_system``.
    8. 

  8. 

  9. 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.
    10. 

  10. 

  11. ESP Clock
    12. 

  12. ---------
    13. 

  13. 

  14. The old headers ``{IDF_TARGET_NAME}/clk.h``, ``esp_clk.h`` have been removed.
    15. 

  15. 

  16. Therefore, If you want to use the function with the prefix ``esp_clk`` please include ``esp_private/esp_clk.h`` instead.
    17. 

  17. 

  18. Cache Error Interrupt
    19. 

  19. ---------------------
    20. 

  20. 

  21. The old headers ``{IDF_TARGET_NAME}/cache_err_int.h`` have been removed. Please include ``esp_private/cache_err_int.h`` instead.
    22. 

  22. 

  23. Brownout
    24. 

  24. --------
    25. 

  25. 

  26. The header ``brownout.h`` has been made private. ESP-IDF developers should include ``esp_private/brownout.h`` instead.
    27. 

  27. 

  28. Trax
    29. 

  29. ----
    30. 

  30. 

  31. The header ``trax.h`` has been made private. ESP-IDF developers should include ``esp_private/trax.h`` instead.
    32. 

  32. 

  33. ROM
    34. 

  34. ---
    35. 

  35. 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`).
    36. 

  36. 

  37. ESP HW Support
    38. 

  38. --------------
    39. 

  39. 

  40. - 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.
    41. 

  41. - The header file ``esp_intr.h`` has been deleted. Please include ``esp_intr_alloc.h`` to allocate and manipulate interrupts.
    42. 

  42. - 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.
    43. 

  43. 

  44. SOC dependency
    45. 

  45. --------------
    46. 

  46. 

  47. - 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.
    48. 

  48. - Kconfig option ``LEGACY_INCLUDE_COMMON_HEADERS`` is also removed.
    49. 

  49. 

  50. APP Trace
    51. 

  51. ---------
    52. 

  52. 

  53. 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.
    54.
