2. select esp32-c3 and ESP32-C3-Lyra-v2.0 as target
3. try to compile... (great success✅)
4. copy all files from esp-adf\components\audio_board\esp32_c3_lyra in to project folder (project_name/components/custom_board)
5. Add Cmake/make/Kconfig files like in example
6. Select custom audio board option in sdkconfig
7. Try to build... (error❌) fatal error: board.h: No such file or directory

Hello P0nyHunt3r,

I am just a simple user of esp adf but maybe I can help.

Looking at your project, I think you should move "components/CMakeLists.txt" file inside the "components/custom_board" folder and change it to:

idf_component_register( SRCS "board.c" "board_pins_config.c" "C3_lyra_sys_pattern.c"
                                        INCLUDE_DIRS .
                                        PRIV_REQUIRES esp_peripherals audio_sal audio_hal esp_dispatcher display_service )

You shouldn't need the "components/Kconfig.projbuild" and "components/component.mk" files.

Hope that helps.

@rjoly-getraline I tried to do it this way, but it didn't work completely. log

I noticed that my "custom_board" folder appeared in the logs. The libraries that the example uses have "audio_board" in the CMakeList.

[P0nyHunt3r]

After renaming my component folder to the "audio_board", the example successfully built.

I don't think this is an elegant way. Maybe I'm missing something or the esp-adf example is outdated. 🥺

You can modify the CMakeLists.txt file as follows to add custom_board to the environment variable COMPONENT_ADD_INCLUDEDIRS:

# Edit following two lines to set component requirements (see docs)
set(COMPONENT_REQUIRES)
set(COMPONENT_PRIV_REQUIRES audio_sal audio_hal esp_dispatcher esp_peripherals display_service json)
 
message(STATUS "Use customs board component")
list(APPEND COMPONENT_ADD_INCLUDEDIRS ./)
set(COMPONENT_SRCS
./board.c
./board_pins_config.c
)
 
register_component()
 
IF (IDF_VERSION_MAJOR GREATER 3)
idf_component_get_property(audio_board_lib audio_board COMPONENT_LIB)
set_property(TARGET ${audio_board_lib} APPEND PROPERTY INTERFACE_LINK_LIBRARIES ${COMPONENT_LIB})
 
ELSEIF (IDF_VERSION_MAJOR EQUAL 3)
set_property(TARGET idf_component_audio_board APPEND PROPERTY INTERFACE_INCLUDE_DIRECTORIES  $<TARGET_PROPERTY:${COMPONENT_TARGET},INTERFACE_INCLUDE_DIRECTORIES>)
 
ENDIF (IDF_VERSION_MAJOR GREATER 3)
