Hi friends,
my board is devkit-mpc5744p rev E1. There is a problem when adding sending call to CAN0, there is no received or sended complete callback triggered any more.
what is the context of my code and board is:
1.use CAN0 for receiving and sending with PB0 and PB1 on board, jumper J174 set to 4-6 and 3-5.
2.use USB power.
3.send 0x210 frame every 1 second.
Had anybody have the same problem? You can try my code on your board.
Hi,
I tried your example and it worked fine, but I used SBC's CAN transceiver and so external 12V to power a board, with board connected to PCAN tool. It should work with USB power too, but if you connect PB0/PB1 to headers, do you have these CAN TX/RX signals connected to external transceiver and this transceiver via CAN bus to other CAN node, so a transmitted message can be ACKed? Not sure of further connection you have. Where PB0/PB1 are connected to? Check if your external CAN transceiver is functional.

Hi Petr,
I have found the problem, there is no external transceiver connected to PB0/PB1. It had been resolved by using SBC's CAN. The program is running happily now. Thanks for your help.
