Implement Jetson Secure Boot without UEFI Secure Boot on Jetson AGX Orin

Hi Jerry,

So, I think I “fixed” it, but would like an explanation for why this needed to be done.

I came across another post (JetPack 5.1.3 - Boot error with all security enabled - #7 by resi58) where it was recommended to create another “eks_t234.img”. I generated a new image with all the default keys “0s” and used that image to flash and boot. I was able to do so successfully. I now have a Jetson running with secure boot enabled for its bootloader components and UEFI without secure boot.

So the question is why did I need to do this? Does the default "eks_t234.img’ not have default keys of “0s” already? Wouldn’t I have encountered the same issue before I made the Jetson bootloader secure boot change?

Thanks,
Jim
