Hello, @Niranj_369
Thanks for your reply.
The AN13750 is based on S32G2, the method is also workable for S32G3, however, since hardware/software version differences, it is not fully compatible with S32G3.
If you are working with Platform_Software_Integration_S32G3_2023_02, then you have to install the packages that list from the release notes of "Platform_Software_Integration_S32G3_2023_02" in advance,(which may not the same as mentioned in AN13750) and then try loading bootloader project to the EB as described by AN13750.
Sorry for your inconvenience.
