Unable to debug S32K324 using S32 Design Studio and JLink Base

[yeshvanth-m]

I'm trying to flash and debug the sample program for the NXP S32K324 Triple Permanent Magnet Synchronous Motor Control Reference Design Board. I'm using a SEGGER J-Link Base debugger, the debugger can detect the core - I tried it via the JLink commander as well, but when I try to launch the debug session it always throws an error saying the JLink GDB Server is unable to halt the core. Here is a snapshot of the complete log.

So the issue was with the board. This issue no longer occurs, but now there's another issue:

Any idea why this error is popping up? I have built both projects for the M7 cores.

I restored defaults in the debug window and it seems to be working now.

In current implementation of S32DS, JLink server is a minimal set of binaries which might not work correctly. In order to address this issue, download https://www.segger.com/downloads/jlink/ latest version x64, install and browse to installed location, ex: C:\Program Files\SEGGER\JLink and pick JLinkGDBServerCL. This issue will be addressed in March 2024 release of S32DS Platform.

Although K324 can do multicore, Segger's JLink doesn't offer this functionality out of the box.

I debugged this with Jeremy. There's an issue with the board - the JTAG/SWD reset pin is asserted high by the MCU only. I need to replace this board with a new one maybe..

Hi

Could you try update the newest Jlink driver and make sure it gets updated in the S32DS installation folder.

This is the log when I debug S32K324 with Jlink at my side. And make sure the GDB port of the 2 core debug instance need to be different.

Hi Jeremy,

Thanks for your response. But the problem still exists. I will provide all the configurations I used for better understanding.

With SWD and port ID 2334 as you suggested I get this error:

Same error with JTAG as well

What code is flashed at the factory? Is it something to do with corrupted code? Not sure about it.

Hi @yeshvanth-m,

Please take a look into the NXP S32K3xx - SEGGER Wiki. Here, you can find the supported regions for the S32K324, as well as an example and a script for SystemView.

Best regards,
Julián
