Hi @VaneB ,
I have 2 boards.
1) Target board which is having S32k324 Controller.
2) S32k344 Evaluation Board(257 package).
As per your suggestion i have created application project for both the controller.
So, there is no problem for S32k324 application project. If I'm trying to flash application project for S32k344 evaluation board then error is occurring. For your reference, I have attached image in below.

But, Same project I was trying to flash from my colleague laptop then there is no issue. Could you please help me to solve this issue and let me know if you need more information.
Regards,
Ajay. R
