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

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.

Jian

Wolfgang,

Two separate issues here:

1. NAND environment support: It is in CVS. It is called env_nand.c.

2. 16-bit NAND support: I was just wondering if anyone wants to patch
cmd_nand.c with 16-bit support. I have it working for my board but it is
just a hack. I can share my code with others who hopefully makes it a
patch to cmd_nand.c. 
 
Regards,
Jian

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
