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

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

[claudio123]

Hi,

Has anybody used 1GByte nand flash with 1 die and oobsize of 512, oobblock
=4096.
Do you know how to create the "static struct nand_oobinfo" in nand_base.c 
for a oobsize of 512.
Does anyboody have support in uboot or linux kernel for such nand flash.

Thanks

Regards

Claudio

It would be much more useful if you stated what the part number and
manufacturer were.

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

[Stuart Wood]

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.

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

[Spinelli, 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

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

[Stuart Wood]

Claudio,

This does not appear to be a standard large page device witch has;

page size of 2048 bytes plus 64 bytes OOB
block size of 129KiB plus 4096 OOB

Do you have the data sheet or are you determining the information
below from the ID byte?

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

[Stuart Wood]

Thanks Claudio for the information,

I've taken a look at the data sheet and it does not fit the typical
large page flash, but It does not mean its not supported under Linux
which is were the FLASH subsystem in U-Boot comes from. Neither am I
familiar with the open nand flash interface onfi.org. BUT this should
not be too difficult to add to u-boot or the Linux's MTD layer. The
hardest part is the odd OOB size. It's 10 Bytes longer than twice the
large page size.

Look at the MTD pages for help porting
"http://www.linux-mtd.infradead.org/doc/nand.html"

Good Luck

Stuart

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

[Stuart Wood]

Claudio,

In the data sheet I can not find a reference to on oobsize of 512, But
I do find the 0x2E on page
24 under byte 3 description.  It brakes down to;
page size => 4K
Spare area size (bytes) => 218
Block size => 256KB
Organization => x8
Serial access (MIN) => 20ns

I did find a reference to this architecture size as being the next
generation on large NAND flash  devices.
you can find it at
"www.toshiba.com/taec/flashsummit/NANDIntro_FlashMemorySummitv_7_6-21-07.pdf"
page 14, shows a road map. Also the check out the ONIF 2.0 spec. I
also references the larger size.

Unfortunately If you need this soon you will have to implement it, but
then you name can go down in
history. Otherwise since this looks like the tren for newer larger
flash chips it, someone eventually will
implement it, but probably not on your time table.

Good Luck

Stuart
