[LinuxBIOS] Digital Logic msm800sel

[Otávio Alcântara]

Hello,

I'm porting linuxbios to a plataform similar to msm800sel board (same
processor, companion e superio) and I'm in doubt about burning flash memory.
After compiling the code the generated elf format linuxbios.rom file can be
used to burn the memory or there's another step to convert the file to a
binary format?

Regards,

[Uwe Hermann]

Usually you flash the linuxbios.rom, yes. If this is the first time you
do it, make sure you have a backup facility (extra chip with your
original BIOS etc. etc.)

Thanks Uwe,

I flashed the linuxbios.rom and used a JTAG interface to debug it.
But what happens is I can't see the initial jump in the rom code. I tried
other rom from http://qa.linuxbios.org/overview.php and the same problem
happened. With the original rom image I can debug with no problems.
     Do you know what could be the problem?

Need more info, I'm not sure I understand where your problem lies.

Do you get serial output over a null-modem cable?
