[Xen-devel] Help on getting serial output on the arndale board

[Birin Sanchez <birintxo@xxxxxxxxx>]

Hi,

Now that the Arndale board is supported in upstream Xen I don't get any 
output on the serial console. I followed the instructions on the wiki 
with no luck:
The xen repository I'm using is:

git://xenbits.xen.org/xen.git

last commit: 61c6dfce3296da2643c4c4f90eaab6fa3c1cf8b3

The linux repository is:

git://xenbits.xen.org/people/julieng/linux-arm.git

last commit: 3f35c6f2b805901fbde2ce7553478a8cd4249a33

The linux-domU repository is the same but branch arndale-domU-3.9:

git://xenbits.xen.org/people/julieng/linux-arm.git

last commit: 510c35298dfbb6ccb0d883cb34a27eff2f291cea

I tried to add 'CONFIG_EARLY_PRINTK = exynos5250' and 'debug=y' in 
.config file and in Config.mk but still no output.
This is all I get:
