board.mk file missing for the esp32s2 boards

[Ivo44]

I'm trying to compile USB midi test for the feather esp32s2, and after fishing for the includes,

I get the error in "tusb_config.h" that CFG_TUSB_MCU must be defined.
Inside "tusb_config.h" it says it's defined it "board.mk", but such file doesn't exist for any of the esp32s2 boards, only a "board.cmake" and "board.h".

Am I missing something here? Or is the board.mk really not present for the esp32s2?

The esp32 does not use regular make for its build system, hence why you can't find board.mk, board.cmake does its job.

if you look inside you will find

target_compile_options(${COMPONENT_TARGET} PUBLIC
  "-DCFG_TUSB_MCU=OPT_MCU_ESP32S2"
  "-DCFG_TUSB_OS=OPT_OS_FREERTOS"
)

that sets that particular variable.

not sure why you cant compile.
