Hello, I keep getting unexpected exception errors on my IP1000 with builds
over
the past 6 months or so. The unexpected exception errors are random
errors
and are different every time, but seem to happen right about the time
the
vga rom loads. I think it has something to do with x86emu and yabel
loading
the vga rom. If I change it to boot up with out graphics it boots up
every
time, no problem. If I enable the vga device (2.0) and allocate vga
memory
but not load the vga rom it boots up every time no problem. So this
tells
me it doesn’t like something the rom emulator is doing, right? This
is
very strange because I do not have this problem with the RM4100… just
the
IP1000 (brother boards).
You could well be tickling a but in either emulator. These are hard to find. It's handy to have a user-mode wrapper so you can run these emulators under linux -- much easier to find that way. Is this possible with YABEL?
Could I try something like vbetool?
Not right now, but you can connect to coreboot via gdb over serial, which gives you a user space frontend with single stepping...
Do you mean http://www.coreboot.org/Debugging ?? I tried that, but the errors are different everytime and not always in the exact place so it is hard to put a finger on it using this method.
Did you try a backtrace in those cases? What did it say?
