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.

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

Hi,

does U-boot support 16Bit wide NAND flashs? If I look inside the cmd_nand.c only u_char are used.

Does someone have experience in using U-boot only with NAND flash (maybe 16Bit NAND flash) and SDRAM and an ARM with NAND boot option? I think it is not possible to store the environment of U-boot

in

NAND flash so I cannot save the environment.

Thanks Hermann
