Hi All,

i am following following issues when using samsung flex-onenand of size 1GB.

1. I am doing following steps,

0) onenand erase force  0x200000 0x6400000

if i erase full onenand my oneboot and uboot also get erased( which
are at first block of onenand) i do not know is there different erase
command for SLC and MLC.
if any body is having idea how to do pls let me know.

onenand_erase: start = 0x06500000, len = 131072
onenand_erase: start = 0x06520000, len = 131072
onenand_erase: start = 0x06540000, len = 131072
onenand_erase: start = 0x06560000, len = 131072
onenand_erase: start = 0x06580000, len = 131072
onenand_erase: start = 0x065a0000, len = 131072
onenand_erase: start = 0x065c0000, len = 131072
onenand_erase: start = 0x065e0000, len = 131072
OK
