ESP32 custom component with ULP code link failure
Posted: Fri Apr 09, 2021 5:24 pm
I wrote a custom component (keypad_rotdecode) which also uses some ULP code (debounce_decode.S).
This is the directory structure:
build
components
____ keypad_rotdecode
________ include
________ ulp
main
The project root has this CMakeLists.txt
The /components/keypad_rotdecode/ directory has this CMakeLists.txt
When building the project I get the following error:
[3/4] Linking CXX executable keypad_rotdecode.elf
FAILED: keypad_rotdecode.elf
and later:
undefined reference to `reg_wait_task'
and more like this. These functions are defined in the C code residing in
/components/keypad_rotdecode/
This seems to be similar to the issue reported here:
https://forums.freertos.org/t/integrati ... rtos/11822
Any ideas?
