Hi Miroslav,
I have made further improvements .
With the change in boot parameter I was able to boot from nand.
Issue is the booting is not consistent it fails to load the filesystem randomly.
Below are the error messages when booting fails
[ 1.368408] uncorrectable error :
[ 1.385009] uncorrectable error :
[ 1.400634] uncorrectable error :
[ 1.431915] uncorrectable error :
[ 1.446502] uncorrectable error :
[ 1.463134] uncorrectable error :

[ 1.501342] UBI warning: process_eb: valid VID header but corrupted EC header at PEB 599
If you have any input to debug this issue please share.
Regards,
Dibin
