ChibiOS Free Embedded RTOS

I have a custom stm32 board with a stm32h743vit6 chip which is specifically designed for a project, and i want to use chibios as the framework and rtos. as the guide indicated for custom board (https://www.youtube.com/watch?v=HwJqZfITvV0), I did the board file generation by modifying the .chcfg of the reference board. but after compiling and flashing the blink led program, it didn't work. does it have anything to do with the reference board that I use, because the stm32h7vit6 that I use provides 100 pins while my reference is from stm32h743zi which uses 144 pins ?
Thanks

Hi,

It does not depend on package alone, there must be an error somewhere, probably in board files. Make sure clock settings are correct.
