Asking here due to forums activity and the same vendor as I have.
We need to boot the signed u-boot image.
The initial ROM loader is checking whether the key is correct and continue loading of the image (looking at flow chart in technical reference man).
All I found is signGP util (and don’t know if it’s really what I need).
So I need to know what docs I need and is there availabe tools at all do do what I need.
