Hey. I have a question about adding a new FCU board. I have JHEMCU_GF30F405 which is very similar to already ported JHEM_JHEF405. I managed to upload and run firmware on GF30F405 board but I have a strange problem - if I edit existing and working JHEM_JHEF405 hwdef file, setting proper details of GF30F405 board and setting a new board id It works and I can build and run a firmware. If I copy those files as a new directory inside AP_HAL_ChibiOS/hwdef - exactly the same files I just uploaded, but as a new directory - it fails to run after powering on. So - if I use existing directory and adjust hwdef, including new APJ_BOARD_ID - it works, if create a new directory - it does not run - it uploads, but doesn’t run. Any ideas?
