I’m attempting to update a Zeus build to Yocto Scarthgap. The Zeus build was created by following the instructions in the first post in this thread. A few things required tweaks to support Scarthgap - the u-boot patches needed re-applying, and manually tweaking the conf files. Now it’s building fi…

Hi @tloten , Thinking a bit about your description, I think your analysis is right - unless we are both overlooking something weird. As a first shot, can you diff the kernel configurations? It should be possible to extract both from the build directory. Greetz, Josef

But still getting the same error :frowning: For reference, the Zeus kernel was 8.5MB. It’ll be a few weeks before I can get b…

One thing I recently noticed about the Zeus boot process is that it prints an EFI stub error, but still proceeds to boot successfully (and has been reliable for 4+ years on hundreds of devices). Zeus boot log (doing u-boot → grub → uefi stub → kernel, as per the Zeus board integration thread here )…

Greetz,
