Hi all

I build os for embedded target. I make initrd.gz file (using TOOLCHAIN/rootfs/).
And I put initrd.gz along with syslinux.cfg and vmlinuz (vmlinuz_2.6.21.7-dist) in CF(compact flash). At the time of booting its giving me error:
"Kernel panic - not syncing VFS: Unable to mount root fs on unknown block (0,0)."

how can I fix this problem?

Sorry for the lates response, general work and CeBIT preparations just
saturated at least me.

You probably have not suppoed a root= parameter to the linux kernel to find
it's root file-system.

If you need further help please post some more details to deduce a
definetify guide to boot your board.

Yours,

hi

syslinux.cfg contain:
"default vmlinuz root=/dev/ram0 initrd=initrd.gz ide=nodma PMEDIA=ideflash PKEYS=us"

I think this is right.
Then what is problem?

Thanks & Regards
