Hm, sounds bad.
You didn't answer my question, though. Did you try using a null-modem
cable to see if you get serial debug output? Maybe something's wrong
with your jtag (or other) setup?
Which code exactly are you using? Please send a patch if it's modified
from what is in svn. How are you building LinuxBIOS? How big is your ROM
chip? How big is your linuxbios.rom? What's the contents of your
targets/.../Config.lb file? Which payload are you using? How did you
flash linuxbios.rom on the chip? Are you sure that worked ok?
Do you have a POST card? What does it show? Does it "hang" with a
certain value at some point?
