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.
