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

Thanks Julien, it works now!
Now, I can start /bin/bash as Linux init process :)

Sincerely,

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

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

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

Hi Julien,

I am trying to use Xen on Arndale board with instrunction on page
http://wiki.xen.org/wiki/Xen_ARM_with_Virtualization_Extensions/Arndale

I am also facing a problem similar to the one that you debugged
before. Translation fault is happening at level3. The fault happens
when 0x12c20008 is accessed. This location happens to be a register of
UART2 port on Arndale. A part of the log is below. Any idea what
caused access to UART to fail?

(XEN) Device-tree contains "xen,xen" node. Ignoring.
