Dear all,
Yes i am using P1020RDb board.
Actually i have to make 2 boot(u-boot) B1 and B2
B1 is stored 0x0000_0000,B2 is stored in 0x010_0000 of nand flash.
when 1 power cycle is given
Board gets booted from 0x0000_0000
my requirement is to boot B2 from 0x010_0000
how can i do that?
Regards
Manukumar
