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...
