I am using the FlexCAN on the FRDM-K64 demo board starting from the example.
It happened several times that the internal controller stall on TxBusy status and I am no longer able to send any packets. How should this situation be managed and restore the correct functioning of the CAN controller inside the micro? In the example the callback only manages the RxIdle and TxIdle states.
Thank you very much!
