Re: [Xen-devel] Testing xen-arm on Arndale

[Sengul Thomas <thomas.sengul@xxxxxxxxx>]

I'm using the root file system from "http://snapshots.linaro.org/quantal/images/server/" and it lacks a lot of stuffs for running domU.

Are you also using RFS above or another one?

Also, if you have a working RFS that can launch domU, could you post it on wiki?

Thanks always,
Thomas

It's seems the kernel is unable to start when the zImage is loaded at
0x40007000. If you change this address, both in U-Boot and the DTS, by
0x60000000 the kernel is able to start.

I updated wiki page with the new instructions and the new device tree.

Cheers,

Julien
