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

Dear all,
In u-boot(u-boot-2010.12)
That's almost two years old. Please upgrade.
- The TEXT_BASE address is 11001000.
Judging from this you seem to be using either P1010RDB or P1023RDS (or maybe some out-of-tree board?). Always let us know what board you're talking about.
- Nand Flash Erasing at Address 0x00000000
- Nand Flash Writing u-boot-nand.bin at address 0x00000000
- When Power is switched On the booting happens.
till this there is no issue, now i want to change the booting address to different location(ex:0x02000000)
Because you don't have as much RAM on this board, or some other reason?
do i want to change the TEXT_BASE address accordingly to boot it from 0x02000000. like below,
- The TEXT_BASE address is 0x02000000.
- Nand Flash Erasing at Address 0x02000000
- Nand Flash writing u-boot-nand.bin at address 0x02000000 .
Did you update other relevant variables such as CONFIG_SYS_NAND_U_BOOT_DST and CONFIG_SYS_NAND_U_BOOT_START?
Plus you really should leave that 0x1000 offset in there. On mpc85xx NAND boot, TEXT_BASE is 4K after the start of the image, since the boot page comes first.
