Hi.
I'm using am3352 at custom board
it' has nand flash ( MT29F8G08ABACA - Micron )
I'm modify boot loader . flash info (am335x_evm.h)

i'm start uart boot sequence ..
check info ..
this is print at uart...
NAND: NAND device: Manufacturer ID: 0x2c, Chip ID: 0xd3 (Micron NAND 1GiB 3,3V 8-bit)
and nand write. erase done....it 's not notice error
but boot argument change and write
... example ) serverip=xxx.xxxx..... -> saveenv
this is print at uart...
Erasing Nand...
check_offs_len: Unaligned address
nand0: MTD Erase failure: -22
After boot -uart boot
this is print at uart...
NAND read from offset 260000 failed -74
*** Warning - readenv() failed, using default environment
i'm guess that nand is miss matching ....
that is not support in driver or i'm missing...
Now is problem....
Thanks a lot!
Best Regards,
