Hello @Sathiskumar,
The Device name does not match the project.

Can you select S32K312?
If not, the plugin in S32DS is probably not updated.
Download and install the up-to-date version of the J-Link Software and Documentation pack
https://www.segger.com/downloads/jlink/
Please close the S32DS IDE before the installation.
During the installation while the IDE is closed, it will ask you to update the S32DS as well.
Regards,
Daniel
