[U-Boot-Users] 2K page NAND flash

[Li Xin-a16157]

Hi,

Can anyone confirm me if u-boot supports 2K page NAND flash? 

The struct nand_chip has a member page256 to denote if flash device has 256 byte pages or not, so it looks like 2K page flash is not supported in u-boot. 

Best Regards 
Li Xin

Hi Zhang Jian,

I need to support 16-bit NAND in u-boot on a ppc board. Could you please post your 16-bit NAND code here?

Best Regards 
Li Xin

I have implemented NAND only boot in an ARM board (OMAP1710 H3). The
NAND flash is a 16-bit Samsung chip. The code is not general enough for
a patch. Anyone is interested in making it a patch?

Yes, I did push a patch for NAND based environment. It is available at
U-Boot site.

Regards,
Jian
