Now when I write Openembedded generated kernel to NAND flash it is not working and the log messages and u-boot environment are shown below, Where might be the problem.? Problem with ELDK compiled kernel was that it was not configured to be run OProfile.

[snip lots of boot messages]

I think the bootargs are wrong as the kernel complains about 'Cannot
open root device "mt-" or unknown-block(2,0)'. Try changing U-Boot
bootargs to

setenv booargs mem=120M noinitrd console=ttyS0,115200n8
root=/dev/mtdblock2 rootfstype=jffs2

(notice: no hyphen + linebreak in root=...)
