I am using S32K324 with SEGGER's J-Link Plus for flash programming, and I've encountered some issu

I followed the instructions in the link " S32 Design Studio for S32 Platform V3.4/V3.5 + SEGGER J-Link Plus " for configuration, and I was able to successfully program the flash. However, during debug run, I keep encountering repetitive memory read errors as shown in the attached image.

Later, I referred to the solution provided in " ERROR: Can not read register 15(R15) while CPU is running ". I performed a flash erase using SEGGER's J-Link Commander and then reprogrammed the same code. However, I am now encountering repetitive messages as shown below.

In theory, SEGGER should support debugging for S32K324. However, I'm not sure why the issue described above is occurring. Can anyone provide guidance on how to resolve this problem?Thanks.

Additionally, here is the current GDB Debug configuration for reference:

Hi, 

please try to install latest Segger j-link drivers - https://www.segger.com/downloads/jlink/  the installer will ask if S32DS drivers should be updated as well.

Hi jiri,

I have downloaded the latest version of the J-link driver (V7.92b), but there's a strange issue. My computer already has S32DS V3.5 installed, but in the final step of the J-link DLL update, the prompt for the V3.5 update does not appear. It looks like the screenshot attached.
