Can we use SEGGER ARM Debugger to debug S32G-VNP-RDB3's M7 Core?

[Jimmybai]

Hello,

     We are try to debug S32G-VNP-RDB3 board using SEGGER ARM Debugger. The SEGGER driver is V9.85, which support S32G399A's A53 core and M7 core(We mainly want to debug M7 core). The IDE is S32DS.3.5 and RTD is S32 G3 4.4.4. When we try to download *.elf file to board, the GDB server always prompt me that the S32G399A is not regonized(S32G399A-M7 and S32G399A-M7-0 also aren't regonized). Can you tell me how to set the SEGGER J-link debugging to debug S32G399A board?

Hi，Jimmybai

Thank you for contacting us.

For S32G, the recommended debugging method is to use S32 Debug Probe and Trace32. Both of these debuggers can be used in S32DS, and Trace32 also has its own official IDE.
Although J-Link has officially stated its support for S32G RDB2/RDB3, you can refer to the following links for more information:

https://kb.segger.com/NXP_S32G-VNP-RDB3

https://www.segger.com/supported-devices/nxp/s32g3/s32g399a_m7_0

However, for the S32G, there is no relevant information to provide the use of Jlink in the S32DS IDE.
