Hai,

I have populated ST 64MB chip and found that the nand flash commands work for ST 64MB chip.But the same NAND flash drivers does not work for SAMSUNG flash , Any Help?

Also one more issue is that the linux kernel boot is not seen after the "booting the kernel." , even though the kernel image works fine in old u-boot version 2009-08

Any help Please?

Arun
