Did you connect serial console? You should get some sth from the serial

Thanks for the help. I changed the option FALLBACK_SIZE=262144 in the
targets/newisys/khepri/Config.lb and I was able to build the khepri.rom
file  of size 512K. Would be nice to document the same somewhere.  


I also managed to try loading the same on a khepri board that I could
lay my hands on. 

However the system did not boot . Is there a way to enable some beep()
or something similar early on to know that the 

processor has started executing the LinuxBIOS code. I do not have a
scope or other hardware that I could use to probe.

There was some output on the serial but that from the service processor
that my khepri board has.

 Any pointers?

  I am new to LinuxBIOS. I downloaded the latest snapshot of LinuxBIOSv2
and tried building it for a couple of boards (newisys/intel etc). 

I was able to build it for intel but when I tried to build it for
newisys/khepri I got the following error:


gcc -o buildrom
./buildrom linuxbios.strip linuxbios.rom payload 0x20000 0x20000 
payload (77000) + linuxbios (131072) size larger than ROM (131072) size!

make[1]: *** [linuxbios.rom] Error 1
make[1]: Leaving directory
make: *** [fallback/linuxbios.rom] Error 1

I disabled the fallback option and then was able to get the khepri.rom
whose size was 384K. I am using the FILO as the payload. 

Is the size of 384K fine? Has any one used LinuxBIOSv2 on khepri? Would
appreciate any help.

Pls. let me know if any addl. info is reqd.


The gcc version is 3.4.3
