[U-Boot-Users] Support for Samsung 1Giga bit NAND device

[Laurent Mohin]

Andy,

The patch can be found at the following link :
http://sourceforge.net/mailarchive/message.php?msg_id=7733528

I don't know if the K9K1G08UOM device is supported by U-boot and Linux, but it won't be very difficult 
to add support for it.

Laurent

Thanks for that. Any idea where I can get this patch?

That's interesting. Is this device supported by U-Boot and Linux?

Thanks.

Many thanks, I'll look into it.

Andy,

U-boot 1.1.0 doesn't provide support for NAND flash with a page size of 
2K-byte instead of 512 byte (and you're right, theses devices require 
special handling).
Pantelis Antoniou submitted a patch on 2004-04-30 which seems to manage 
these new chips, but I don't think it has been added to the latest CVS 
tree.

By the way, Samsung also offer 1 Giga bit devices with a 512 byte page 
size (K9K1G08UOM - Manufacturer ID : 0xEC, Chip ID: 0x79).

Hope this helps,

Laurent

Hi,

Can anyone tell me if U-Boot has support for the Samsung 1 Giga Bit NAND
devices (Manufacturer ID: 0xec, Chip ID: 0xf1)?

I understand these devices have an unusually large block size, that
needs special handling. Is this correct?

Thanks.

Andy

Pantelis, do you have any idea when this support will be ready to enter
U-Boot proper?

If the answer isn't 'soon', how much effort would it be to add the
necessary support for this particular chip? (Manufacturer ID: 0xec, Chip
ID: 0xf1)

Many thanks.

There was a new updated patch posted recently.

I'm not quite sure if it handles these chips correctly.
You could try the latest patch and if it does not work
contact me.

Where can I get this patch from? Is this the one Laurent was referring
to (on 30th April)? If so, you say in your message that it's not ready
for inclusion yet...

Thanks.

Search the list archives...

It is ready for inclusion, it's just that the Samsung chips are a bit
strange and I have none to test.

Laurent posted me this link:

http://sourceforge.net/mailarchive/message.php?msg_id=7733528

However, if I go there, then there is no patch (the message says a patch
is attached...)

There is also this message:

http://sourceforge.net/mailarchive/message.php?msg_id=7733555

Again, I can't get at the actual patch from there.

Am I being stupid? (quite probably...)

Ok, when I get the patch I'll give it a go and let you know how I get
on.

Thanks.

Pantelis,

yesterday I started hacking U-Boot to support Samsung K9F1G08U0M NAND
flash (2k pages). After few hours I feel you were right - NAND code
needs rewrite and I'd like to help you with that. Could you upload your
patch (or even working tarball) somewhere? Searching mailing list
archive is useless, because you posted patch as attachment and
sourceforge's mailing list archive cannot handle that.

thanks,
