setting a breakpoint:
Help says this: bx <address> [pass count]

So I do this:
bx 0x110000

And it says:
usage: bx [pass count]

or some such. Marc, how to set break point?

Lose the 0x - simnow assumes everything is hex.  Yes, it annoys me too. :)

now I have a plan 9 elf file which I'm trying to jam into a buildrom image.

First try was custom payload, but that's a bit unpopulated :-)

second try was make a tint buildrom, then
cp plan9.elf deploy/tint.elf

but I'm getting the 'that's not an ELF file' error at boot time (I
really miss v3 at times like this :-)

Any suggestions? Do I need to mkelfimage the elf file from plan 9?

thanks

? It works for me with an ELF file.  You just copy the ELF to
deploy/plan9.elf, then specify deploy/plan9.elf as the custom payload.
That's not working for you?

Make sure when you switch payloads with v2 that you remove the payload.elf
or payload.elf.lzma file from targets/vendor/board/board/ because we don't
have that dependency right.

I thought you said it was already an ELF?

Thanks,

yah I got it. This is the K8 plan 9 kernel, machine type was set to
62, and coreboot did not accept that. I just set it to 3 for now.

But plan 9 assumes that loader has set up identity map, so it fails on
that anyway. I'm thinking about that now.
