[Xen-devel] ARM bare metal application test

[Ivan Pavić2 <Ivan.Pavic2@xxxxxx>]

Hello,

I'm trying to build simple bare metal application on ARM Cortex A7.
I reached the phase in which I successfully created domain. Now,
I would like to check if application is really running (it runs according
xl list). But i need some simple interaction or at least console output.

So far this is my code:

    .section ".start", "x"
    .align
    .globl    _start

_start:
    @ zImage header
.rept   8
    mov     r0, r0
.endr
    b       work
    .word   0x016f2818      @ Magic numbers to help the loader
    .word   _start          @ absolute load/run zImage address
    .word   _end - _start   @ zImage size
    @ end of zImage header

work:  b work

I've made linker script so that entry point is at address _start and
it is initial value of PC (it is 0x80008000). So is there any quick
way to check registers from dom0 so I can be sure that "work" is
being done? I'm testing this on Odroid XU3 platform...
