S32K324 Boot jump app issue

witness248 — Mon, 16 Jun 2025 13:26:02 GMT

hi, experts

now we are working on s32k324 bootloader and app. before we used multi elf files for project, and bootloader can jump to app successfully, by using below method:

boot: jump to (0x004A4004 + 0x1000)

app: intc_vector -> 0x004a5000, Reset_Handler -> 0x004a5420

but currently, we combine multi elf to single elf:

boot: jump to (0x004A4004 + 0x1000)

app:intc_vector_c0->0x004a5000. Reset_Handler ->0x004a6420

unfortunately, we encounter a issue

core0:

core1:

anyone can support us? thanks in advance.

Hello @witness248,

Can you check the addresses in the memory view?

What do you see in the Configurable Fault Status Register (CFSR) core register when the system hits the Undefined Handler?

It could be a memory fault. If that’s the case, please verify the MPU (Memory Protection Unit) configuration.

BR, Daniel
