S32K344 HardFault

KILLERzheng — Fri, 17 Dec 2021 10:25:14 GMT

Hi, NXP

I configured a project in EB tresos, but when I try to initialize the CAN module, it occurs the hardfault.

I doubt it that there are faults in MCU clock configuration, but I could not find out the way to deal with it.

Could you please help me?

I found the reason of the HardFault, just because the CAN clock has not been enable in the mcumodesetconf of MCU module

Glad to hear that you can find the root cause. It's indeed that you need to enable the Clock in MC_ME partition before starting using the CAN peripheral.
