Sorry, I'm not using null-modem cable only JTAG interface, and it's okay because works with the original bios. I'm using the last msm800sel version from svn, my flash is 521 Kb, my linuxbios rom plus payload (FILO) is less than 64 Kb, I'm not using fallback, and I use a universal program to flash the rom and it's okay too because a program the original bios with it.

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?
Uwe.
