Set up boot parameters on your board::
- efidebug boot add 1 HELLO mmc 0:1 /helloworld.efi.signed ""
+ efidebug boot add -b 1 HELLO mmc 0:1 /helloworld.efi.signed ""
Now your board can run the signed image via the boot manager (see below).
You can also try this sequence by running Pytest, test_efi_secboot,
