Subject: Re: Error when starting kernel with devicetree on tx53
Date: Sun, 12 May 2013 18:12:11 +0000	[thread overview]
Message-ID: <emf29bd203-0329-4bf9-8b13-7176a8062a4f@plh001-think> (raw)
In-Reply-To: <emde4cb769-926c-4395-89e6-073d8c931261@plh001-think>

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
