STM32H755ZIT

Hello,

 

Does the STM32H755ZIT support flashing over CAN? The application note AN2606 suggests that the H75x series does support bootloader access on the FDCAN1 interface, but specifies pins PH13 and PH14, which are not available on the LQFP144 package of the -H755ZIT.

Hello @ahuster and welcome to the ST Community 😊.

On the STM32H75x, Booth LQFP100 and LQFP144 does not support the FDCAN bootloader Since the FDCAN bootloader pins are not available on those packages.

Best Regards.

By the way, you still can use the Open  bootloader for your purpose.

This would allow us to flash over CAN without needing the PH13/PH14 pins?
