There is some gdb support in coreboot, but maybe not for ARM?
What I tried to say is that it happens to early to connect to coreboot
using gdb support, but maybe I'm wrong.
so I used qemu '-s
So, if you comment that one line out, do things work for you? Just
double checking.

Comment is not enough to make it work. VE_NORFLASHALIAS has to be -1, then it
works for me. So patch for QEMU is:
diff --git a/hw/arm/vexpress.c
I can't recall for ARM, it's been more than a year since I used qemu
on that platform. That said, ... on the platforms we use ROM is in low
memory. What's your coreboot system.map say?

I'm not sure what 'coreboot system.map' is but
So what this is saying is that we expect the ROM for coreboot to start
at 64K. I hope this makes sense to you. Does this conflict with some
qemu expectation, do you know?

I suspect our emulator is assuming SRAM in there somewhere, can you
check? Certainly we depend on SRAM on the real

Hi all,
I tried to boot coreboot using latest qemu and figured out that it fails
with:
qemu: fatal: Trying to execute code outside RAM or ROM at 0x0400
R00=0002 R01= R02= R03=
R04= R05= R06= R07=

You can't assume much of anything. That commit seems not that harmful.
What would help is if you tell us more about when the problem happens.
There's just not enough info in your note, but I'd love to try to
help.
Thanks!

Hm.

so I used qemu '-s -S'. Whole qemu command:
qemu-system-arm -M vexpress-a9 -m 1024M -nographic -kernel build/coreboot.rom
Is -kernel
