Error Debug FreeRTOS Example On S32K344 S32 Design Studio@3.6.1

Qiurui — Mon, 21 Apr 2025 12:40:13 GMT

Hi everyone,

I'm currently developing an application for S32K344 using FreeRTOS and encountered a rather strange issue. When I try to step-through debug my program, it consistently gets stuck at static void prvPortStartFirstTask(void), specifically at the assembly instruction svc 255.

The odd part is that the program runs perfectly fine when I simply download and reset it - the issue only occurs during step-by-step debugging.

Has anyone experienced something similar or could offer some guidance? I've attached my debugger configuration page for reference.

Thanks in advance for any help!

Hello @Qiurui,

To be able to help you, please share the following information:

RTD version you are using, so I may try to reproduce the issue locally.
Are you using one of our boards or a custom one? If you are using an NXP board, please share the model.
Have you done any modifications to the FreeRTOS example you mentioned you are using?

Thanks.

Thanks for your reply.

I'm using RTD 5.0.0
The board is a custom design (not an NXP development board)
None modifications on the FreeRTOS example project

I set up the build environment by installing the offline packages listed below.

Hello @Qiurui,

Thanks for the detailed description of your setup. I have tested with the same packages and I successfully debugged the FreeRTOS_Toggle_Led_Example_S32K344 program, I was able to perform step-by-step debugging with no problem. I a S32K3X4EVB-T172, which has a build-in debugger using the PEmicro configuration in S32DS.

From my perspective your issue is related to the Segger-Jlink plugin, I would recommend to contact them directly to know if their debugger features FreeRTOS debugging.

Let me know if I can help you with anything else relate to this problem.
