Hello, unfortunately I can't get L4Re running on the Raspberry Pi 3 / 3+ using the provided Guider (https://l4re.org/rpi.html). I did the 64-Bit setup accordingly with the provided U-Boot and the ready-to-use images. U-Boot itself seems to work fine and I can set the IPs ...
Unfortunately I don't know the address to load the .elf file so I'm using the following commands: "tftpboot bootstrap_hello_rpi3.elf" and "bootelf". After entering "bootelf" the output on serial spews garbage and after a few seconds the same garbage is "printed" in an interval of around 1 second.
Am I doing anything wrong or am I missing something?

Kind Regards
Daniel
