WIC file missing IVT header in S32G399ardb3 build

[s153022]

Dear NXP Support,

I am currently building the NXP Auto Yocto BSP 38_0 for the S32G399ARDB3 machine. I have added WIC card support by including the following in my Yocto configuration:

IMAGE_FSTYPES += " wic.xz wic.bmap wic"

However, I observed that the generated .sdcard file includes an IVT header, but the IVT header is missing in the .wic file.

Could you please advise on how to generate the WIC file with the IVT header, similar to the .sdcard file? Is there an additional step or configuration required to ensure the WIC file contains the necessary boot headers?

Looking forward to your guidance.

Best regards

Hello, @s153022 

Thanks for your post.

From chapter 27.3 of BSP38 UM, when "dm-verity" is enabled from the Yocto configuration, the newly generated image would be with the .wic extension.

This seems the only case which is tested under BSP's perspective for wic image, I have tested it from my local host, the newly generated wic image also include the IVT which is the same as the default .sdcard image.
