I'm trying to get the CAN1 on my stm32f4 board to work. The first time I turn the board on, the code works no problem, but when I press the reset button, sometimes I get an error initialising the CAN peripheral.

I've tried calling HAL_CAN_DeInit, before HAL_CAN_Init, but with no success.

What am I missing?

Does the error provide any specificity? Can you determine any from walking the code in the driver?

Can you try reviewing the state of the pins?
