S32K344 use TJA1153 send can message fail problem

[tianxing]

I made a program with flexcan sdk and I debug on the EVB.

The program can send can message but not all the time .

For example the first time download elf file and run can send the can message successful but the second time download elf file and run cannot send the can message.

Why this happened? Please help me solve this problem.

And the attach file is the program.

Hi,

could below thread be useful for you?

If using S32K3X4EVB-Q257, there is secure CAN transceiver on the board, TJA1153, which is not configured by default and it does not allow the MCU to communicate with the CAN bus. So a config must be done first.
