Hi all,
I'm compiling Redboot for RAM and trying to make it work on my XScale
platform. The code is crashing in a very simple part:
// clear BSS
ldr r1,.__bss_start
ldr r2,.__bss_end
mov r0,#0
cmp r1,r2
beq 2f
1: str r0,[r1],#4
cmp r1,r2
bne 1b
2:
After this cleaning loop I have code to light up a LED, but this code is
not being reached.
I'm also getting the following error on GDB console:
"warning: Remote failure reply: E03"
Before that code is executed I'm doing some hardware initialization and
memory remapping.
Does anyone have any idea of what could be causing this problem?
Thanks,
Cristiano.
