Hi Moshe,
Could you share some more info about the u-boot version that is being used on your ZynqMP device?
Please also try to load a device-tree with bootm. The error message could just indicate a device tree is missing. Simply use the one you probably find on the flash (bootm 0x0ffffc0 - 0x....).

I'm trying to run L4 on a Xilinx ZyncMP board. The board runs Uboot from ROM and then I tried to load L4 as described in https://l4re.org/bsp/zynqmp.html.
However, loading a uimage fails, I'm getting an error:

I tried to use rawimage, but there I get to the following problem: ZynqMP> fatload usb 0:1 0x1000000 bootstrap_hello-cfg.rawimage 2149176 bytes read in 151 ms (13.6 MiB/s) ZynqMP> go 0x1000000 ## S� L4 Bootstrapper Build: #15 Thu Apr 3 11:39:37 IDT 2025, 9.4.0 Scanning up to 2048 MB RAM, starting at offset 32MB Memory size is 2048MB (00000000 - 7fffffff) RAM: 0000000000000000 - 000000007fffffff: 2097152kB Total RAM: 2048MB Scanning fiasco -serial_esc Scanning sigma0 Scanning moe rom/hello.cfg Compressed modules: cannot decompress at 0x10a8000, try 0x11bc000 Uncompressing modules (modaddr = 0x11bc000 (backwards)): mod06: 0x126c000-0x1296b38: hello mod05: 0x126b000-0x126b080: hello.cfg mod04: 0x11e1000-0x126a118: ned mod03: 0x11bc000-0x11e0c40: l4re Loading fiasco found node 0 kernel info page (via ELF) at 0x3000 L4Re is configured for EL2 mode (virtualization / hypervisor) but got started in EL1 by the boot-loader.

I'm not sure how to proceed from here. The Uboot is loaded from the board's ROM and is running at EL2.
Any help is appreciated, Moshe
