hello SDK:
when I use CAN_h\CAN_l frequently, the program always enters "DefaultISR", or CAN receive buffer cannot enter "FLEXCAN_MB_IDLE", which is always busy.Therefore, the original CAN was sent normally, but now CAN CAN no longer restore the original sending state.Can can resume working only through software reset or power-on reset.Why is that?How to solve this problem?
