  To: barebox

Hello,
I try to install barebox 2013.05.0 as bootloader for a karo-TX53 board. 
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.
Patrick

BootScript:
#!/bin/sh

if [ "$1" = menu ]; then
boot-menu-add-entry "$0" "optiMEAS Net-Boot"
exit

Your problem is that this not a devicetree blob.
Of course barebox should not crash then, this seems to be a bug.

Thanks Sascha,
but whats wrong with the devicetree blob?
I mean the same dtb is working, when I boot the board with uboot.

I use ptxdist to build the kernel image and to build the tx53.dtb from 
tx53.dts

Are there some special settings to build the dtb for use with barebox?

What can be wrong with the dtb.

Best regards, Patrick

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.
