Currently uBoot is used. As a first try I load the barebox image with uboot over tftp into RAM and start it from there. Barebox starts and I can access the menu and select my prepared boot-entry 2: Boot: optiMEAS Net-Boot Then barebox loads the Kernel-image "uImage" and the devicetree "tx53.dtb" from the mountpoint "mnt/tftp". But then it chrashes with the error message as stated below. The same kernelimage and devicetree is working when started with Uboot. Where is my mistake? Am I missing some settings? What else do I have to configure when I want to start my kernel and using a devicetree? Thanks for helping.

A dtb must have 0xd00dfeed (big endian) in the first 4 bytes. Your dtb seems to have 0x0000f085 instead so barebox doesn't recognize this as dtb. You could do a: md -s /mnt/tftp/tx53.dtb on the commandline. You should see the magic. Then afterwards you can add the following to commands/bootm.c just below the line printing "...is not an oftree but...": memory_display(fdt, 0, 0x100, 4, 0); The result should be identical and both should have 0xedfe0dd0 as the first value.
