Bus Fault and Hard Fault in S32K324 Controller

[nishanth_s12]

Hi all,

I am facing the issue while eraseing the sector in S32K324 Controller.

When i am debugging the code step by step during the Erase, it works fine. When i am giving the continues run, it goes to Bus Fault and Hard Fault handler.

Kindly suggest the solution.

Hi,

Thanks for your reply.

We gone through the document.

We are unable to find  SRAM (".ramcode" section) in our project.

When we configured flash driver only, it was working. But we configured flash driver along with FlexCAN, Pit_Ip and Port driver, it is not working properly. We are getting Bus Fault and Hard Fault.

Please find enclosed our code. Kindly rectify the same.
