Hi
We are facing a problem of mount root file system .Able to boot kernel in nand flash but it cannot mount ubifs.
Output is

Hi Pramod
one can try first to erase NAND then program rootfs as
describes attached Linux Guide p.19-20 "Root file system on NAND flash"
or use MFG Tools to perform whole operation:
I.MX23_MANUFACTURING_TOOL : Tool and documentation for downloading
i.MX233 image during manufacturing..
Best regards
igor
