I have one more query Is that possible that only a particular precompiled image of kernel can mount a rootfs on NAND, and no other kernel image shoiuld be able to mount? regards -Nitin > Hope this helps. > > Thanks > Sneha > > > > > regards > > > > -Nitin > > > > > > > > New Email names for you! > > Get the Email name you've always wanted on the new @ymail and > > @rocketmail. > > Hurry before someone else does! > > http://mail.promotions.yahoo.com/newdomains/aa/ > > > > _______________________________________________ > > Davinci-linux-open-source mailing list > > [email protected] > > http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source New Email names for you!
