Hi,

We want to use NAND flash on Alchemy Au1200 and have a custom board along with 
Db1200; so tried it both on our custom board and Db1200 without success.
(Because Db1200 has a slot we opened it and replaced the original with our 
part)

Kernel -> 2.6.20.1. Error messages:

NAND device: Manufacturer ID: 0xec, Chip ID: 0xf1 (Samsung NAND 128MiB 3,3V 
8-bit)
Scanning device for bad blocks
Bad eraseblock 0 at 0x00000000
Bad eraseblock 1 at 0x00020000
...
Bad eraseblock 1022 at 0x07fc0000
Bad eraseblock 1023 at 0x07fe0000
Creating 2 MTD partitions on "NAND 128MiB 3,3V 8-bit":

It marks all the eraseblocks as BAD. As far as I understand 
"au1xxx_nand_command" seems doesnt work correctly. Has someone succeded to 
work with these large block parts in the Au1200/Au1550?

Thanks...
