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

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

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

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, ladis
