Can_Init arise hardFault_handler

MNN — Wed, 08 Nov 2023 12:56:52 GMT

hardFault_handler occurred when I was using Can_example_s32k312 of S32K3 RTD AUTOSAR 4.4 2.0.3D2303。

I can do this loopback test when I use the example Can_example_s32k312. But I changed the example from FLEXCAN0 to FLEXCAN2, and running Can_Init produces hardFault_handler. Why is this happening? Can you tell me why?

Hi @MNN

Could you share the changes made to code configurations?

Thank you, VaneB.

Sure am. The following is my modification. Except flexcan0 changed to flexcan2, nothing else was modified. Attached is my project.

thank you

I have solved the problem because I did not enable the clock for can2.
