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

"NAND boot... read failed (ltesr)"
This message is triggered by an uncorrectable ECC error; LTESR[2].
Can any one tell how shall i proceed for booting successfully from large page NAND ?
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.
