The function HAL_CAN_ConfigFilter() takes as a parameter CAN_HandleTypeDef* hcan (a handle) but inside the function will be used a fixed CAN1.

Line 370:

/* Initialisation mode for the filter */

CAN1->FMR |= (uint32_t)CAN_FMR_FINIT;

Should not be used hCan->Instance-> ... ?

#stm32cube #can

Wouldn't that really depend on if the register exists in both CAN1 and CAN2, or if it's only in CAN1.Remember CAN2 is a slave/subset of CAN1
