Hello Julien,

Hello Ivan,

thank you very much, I succeded with debug console and pin toggle (iomem).
It's actually good that you answered late, because it made me look through xen
traps.c and console.c code, so I recompiled xen few times. The main problem with
was compiler, I think. I've always got data abort with hypervisor calls and
similiar. Now I'm using gcc-linaro-arm-none-eabi-4.9 for both xen and
application.

Your guest (i.e the application) and Xen should not need to be built with the same compiler.

Which compiler led to use a data abort? And where was the data abort? In Xen or the guest?
