S32K312 boot with HSE enabled

strofald — Wed, 23 Apr 2025 18:38:32 GMT

Hello,

I have flashed HSE FW on my S32K312 microcontroller, and I have enabled the HSE FW Feature flag in UTEST.
Anyway I experience the following: whenever I flash a new application FW, right after flashing if I step with the debugger (without executing any instruction, just the first one from the startup code), an Hard Fault is triggered. If instead, after flashing, I perform a reset with the debugger, the Hard Fault does not happen.
How is this possible?

May this be related with the IVT configuration?
I am using the standard linker and startup files that are provided with the Platform module in RTD v5.0.0, I attached them below (renamed in .s.c due to update policies)
I also uploaded the .map file of the application.

Hi @strofald

I have never seen such behavior and I can't see a reason for that.

What kind of debugger do you use? It sound like problem of debugger...

Regards,

Lukas

I solved the issue by updating my debugger client (PLS UDE) to version 2024.05
