Hi,
I tried booting a Raspi 4 with a Leap 15.3 USB stick following the instructions on https://en.opensuse.org/HCL:AArch64_EFI which unfortunately did not work.
How did it fail?
It booted from the inserted SD card (w/o card it did just nothing) I interrupted at the uboot prompt, and then?
Then you should be able to execute the bootscript from the environment which loads the system from USB like
run bootcmd_usb0
where the 'run' command executes command list from environment variable and 'bootcmd_usb0' is a command list predefined in the default environment.
Random (unofficial) document that lists u-boot commands is here:
https://www.digi.com/resources/documentation/digidocs/PDFs/90000852.pdf
Note that the availability of commands depents on compiled-in features.
There might be an official u-boot manual but it is notoriously hard to find.
In case of problems you might want to use the usb command to determine if your storage device has been detected (or if you happen to have more than one in which case you may need to specify number other than 0 in the above).
Yes, I could spot the device and partition, but struggeling with the correct boot command: fatload usb <dev>[:partition] <loadAddress> <bootfilename> -> what is the bootfilename it is looking for? when running run bootcmd usb0 (where the USB stick sits) it still boots into the SD-Card @Alexandre - thanks for the hint with the firmware - I updated successful, however the USB stick was not selected at boot.
