Hi, I used latest version of u-boot (U-Boot 2009.08-rc1) for NAND booting of my board. Still, it didn't work. Board starts booting and then says read failed and hangs there. It prints following message on console
"NAND boot... read failed (ltesr)"
I am using 2.1 silicon MPC8313 based custom board with large page NAND.
Can any one tell how shall i proceed for booting successfully from large page NAND ?
Thanks in advance Rupesh

Using similar procedure i tried NAND boot on my custom board but it dint
work :(
My board has large page NAND where as MPC8313ERDB has small page NAND. I
have modified all the parameters required for Large page NAND. It prints initail debug message as shown below and then while copying u-boot code from NAND to DDR it detects NAND blocks as bad block and continuously prints 'B' on Console.
NAND SPL - U-Boot 1.3.0 (Jul 30 2009 - 06:33:05) MPC83XX Loading from NAND :
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB
Can any one please tell what could be going wrong? Am i missing
something
in large page NAND initialization?
Please try the current upstream u-boot rather than the BSP version. Large page support in the mpc8313erdb BSP is likely broken.
