I am using EDK2 https://github.com/tianocore/edk2 on a Raspberry PI 3B model.
Installation went fine and I can access the UEFI Shell interface, where the commands work.
But I'm now stuck and have a few questions :
- Do you have a simple .efi script that I could use to test
- my setup ?


.efi indicated an application (or driver), as opposed to a script.

My go-to test case is a standalone GRUB executable.

Generated with grub-mkstandalone -O arm64-efi -o grubstand.efi



Ok I will try this, thank you !



- Once I am on the UEFI interface, I can't seem to boot
- back onto my OS (Raspbian). Could you please explain how
- to do this?


Does 'exit' bring you back to a "BIOS" menu system where you can select boot options?



Yes, it does, but from there I can't get back onto my OS either. :(



Best Regards,



Leif
