[oe] barebox builds OK but hangs on target at91sam9g20 board

Thu Mar 20 04:24:24 UTC 2014

I am trying to run barebox version 2013.02 on an AT91SAM9g20 board. I 
have downloaded barebox from the linux4sam github (barebox-at91) and 
have successfully compiled using the CodeSourcery Lite and successfully 
ran barebox on the target AT91sam9g20 board from an SD card.
I then tried to build barebox using yocto poky dylan 9.0.1 and started 
with the bitbake recipe in meta-fsl-arm. I made a few minor changes to 
barebox_2012.02.0bb file and barebox.inc.  I am able to build barebox 
with no errors but when I install on sd card the board hangs at the 
beginning of the boot.  I have compared the tags on barebox branch 
downloaded from the linux4sam git to the yocto fetched git and they 
match.  When I compare the compiled zbarebox.bin files the one built by 
yocto is smaller in size then the one built by Codesourcery Lite.  The 
defconfig files and the .conf files are the same.

It seems like there is something that I have not setup correctly in the 
bitbake file or machine config?  Anyone have any ideas?

Here is OK boot of barebox

Hit any key to stop autoboot:  0

At this point the kernel will load and the rootfs will load and run.  
Both built with yocto/poky

I then copy the zbarebox.bin located under barebox/arch/arm/pbl to sd 
card.   I also used file in the deploy directory (both the same) and had 
same problem.
