1 month ago This problem is very strange, torture me for a day. It looks like the problem is on the RP2040 board. I'm not sure, because it crash with static links? Perhaps Zephyr has other problems.

1 month ago Request investigation, Ask for investigation, I recovered on my nrf52840_mdk, the same problem.
west build -p always -b nrf52840_mdk
west flashI also have an ESP32C3, there is no problem, normal. I think the problem may appear on ARM compilation or DAPLink or OpenOCD. Perhaps this is a dual-core problem.

1 month ago Did you try using https://github.com/zephyrproject-rtos/zephyr/tree/main/samples/application_development/external_lib ? Because this is tested and works

1 month ago This makes me difficult to understand, because it is just a empty test function. Arm can't, risc-v ok.

It's ok, The reason is that the compilation option is not applied to add_subdirectory (lib)
