[U-Boot-Users] nand_oobinfo for 1Gbyte nand flash with oobsize=512

[Spinelli, Claudio (Claudio)]

Stuart,

It is as follows:
 
The fourth byte is 0x2E which breaks down as follows:
oobsize = 512
oobblock = 4096
erasesize = 256k
busw = 8

Additional info:
1 page = 4k + 218 bytes
1 block = (4k +218 bytes) x 64 pages = (256k +13k) bytes

Device total size = 8,608Mbit

Thanks

Claudio

Claudio,

OK, Micron does not like to share there data sheets, so I can't look up
the part. You will need to describe the part then.

SLC or MLC? (presumably MLC)
Page Size?
Block Size?
OOB per Page?

With that information people should be able to help you. I, myself, have
never used the MLC NAND Flash so I don't know if it differers from the
SLC types. I do now that both Large and Small page SLC Flash is well
supported.
