S32k322 Linker File Memory Segregation Issue triggers Hardfault

Lisha — Wed, 04 Dec 2024 09:54:24 GMT

Hii,

I am facing an issue in my linker file. As soon as I add a section under int_flash_safeos_c0 and I enabled the MPU (Memory Protection Unit) and divided it into two sections: OsROM and OsRAM. When using it, I encounter a HardFault. I encounter a HardFault on the S32K322 in S32 Design Studio. I am not sure why this is happening. I have attached the Linker here.

Thanks,

Lisha

Hi @Lisha,

I understand this is a MemManage fault.

You should be able to find the memory address and the PC address of the fault instruction, refer to these documents:

Anyway, this is caused by the MPU that is configured in system.c

Please check the starting address, size and all the attributes of each descriptor.

Regards,

Daniel
