Hi,
I have got a new board " waveshare" with "stm32f746Igt" (CRYSTAL 8MHZ ).Core746I-Schematic.
I have started with chibios demo chibios2111/demos/STM32/RT-STM32F746ZG-NUCLEO144 . my programmer is st-link v2 .
The code is freezing in "stm32_clock_init" function. I haven't have any idea what is the problem
Note "I have tested 2 board with same error".

Best regard.
asd

Hi,

Something is wrong with your clock settings in board.h, DO NOT use an existing board.h for another board, you need to create a new one specific for your board. Probably it is related to HSE bypass.
