Hi Wolfgang Denk,
Thanks a lot for your reply.
Actually problem started when i added few utilities in flash. I ll explain the scenario.
I had a working jffs image with bin , boot, scripts as directories in it. uImage(Linux kernel image ) was contained in boot folder.
For my application i had to add few new networking utilitiess like iptables, brctl, racoon etc.. Hence i added these utilities in bin directory and created a new jffs image.
This jffs image was flashed to board. This image gave the CRC error when uboot tried to boot.
Now instead of adding the utilities to bin i added all the utilities to a new created Utility Directory. This time It worked fine. The jffs image was flashed and uboot successfully loaded uImage and booting was perfect.
What might be the reason behind this? can u please throw some light on this?
Thanks Rahanesh

I am trying to boot Linux from flash on MIPS Board. When uBoot tries to boot Linux it fails saying "Verifying Checksum Failed.... bad data crc".
CRC is one type of checksum.
What might be the problem when it is loading uImage from flash?
Obviously the loaded data are corrupt. Based on the information you gave us it is impossible to tell if the data are already corrupt in your JFFS2 file system, of if they get corrupted when loading the file, or when booting it.
