S32K344 debugging with Segger J Link and S32DS

swcoder — Wed, 02 Feb 2022 14:45:56 GMT

Hi,

I have a S32K3X4EVB-Q257 evaluation board and have installed S32DS 3.4(Update 3) IDE.

Segger J link version is 7.60f.

I am trying to debug the Digital IO Led toggle example on the board through the IDE with Segger J link.

However I get the following error on debug window. I am not able to see the disassembly or place breakpoints.

My settings for debug are:

Debug output console:

Can anyone please guide me on this.

Thanks

Hi,

I can reproduce your issue. On my side - sometimes - especially with very first debug session - it works normally. But next debug session fails in the very same way like on your pictures. With PE Micro it works normally.

I didn't find the reason, it is probably something with Segger plugin - you can ask on Segger's forum.

Does it work with the on board debugger with micro USB cabel?

Can you verify that once please?

Or does it give the same issue?

Hi,

yes, debugging works with Integrated PE micro debugger or wot external PE Micro debug probe.

What if using a PE Micro debugger is not an option? We have to use the J-Link debuggers in our project.

I just don't understand how come we are not able to use a basic example project for the board that is meant to be used with the J-Link debuggers apart from PE Micro ones?

Lots of issues with the SEGEGR debugger. FreeRTOS will not go past the SVC instruction to start the first task. Please please please get someone at NXP to test this and debug it, it is crucial for any project that's not using an eval kit

you need to use hard reset when using SEGEGR debugger. when just using soft reset, there are some regs not be reset.
