[U-Boot] NAND booting of MPC8313 based Custom board

[Rupesh Kumar]

Hi
Thanks for reply.
I changed ECCM bit and it fixed "NAND boot... read failed (ltesr)" 
problem. 
However, now it again stuck after printing transferring control.
It lookes like it is able to copy u-boot image to RAM but not able to run 
from there.
What could be problem in this ?

Thanks
Rupesh

This message is triggered by an uncorrectable ECC error; LTESR[2].

This sounds very similar to problems I initially had.  Odds are your are
burning you LP NAND with the ECCM (FMR[23]) set incorrectly.  So the NAND
read is failing because it is reading the correct ECC from the wrong
offset, hence making it incorrect and uncorrectable.  Double check that 
and
see if it helps.
