Hi,

The demo I use is SPC560BCxx_RLA CAN Test Applicaiont

Debug LOOP Mode is OK.

In Normal Mode, when I use can_lld_transmit to send CAN messages, the status returned is always CAN_MSG_WAIT. Can you help me analyze this problem?

A preliminary confirmation is that can_lld_is_tx_empty returns FALSE causing the whole problem.

The configuration inside Demo is just to remove the FlexCAN Enable LoopBack.

Below is SFR:

Did you check connecting it with a CAN network? As well, if you are using a discovery board, you might need CAN transceiver in order to get CANH & CANL signals.
