Hello All,

I am trying to upgrade from u-boot 2009.08 to u-boot 2013.04 so that USB support is possible at u-boot. But now the situation is, USB is working but not NAND at u-boot.

Can anybody help???

HI Manjunath

nand is supported for configuration of Sabre AI boards, like uboot.../configs/mx6qsabreauto.h

http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=RDIMX6SABREAUTO&fpsp=1&tab=Documentation_Tab

also it is useful to check pinctrl driver for nand pins usage.

Best regards

Hello Igor,

In u-boot-2013.04 source i am searching for Nand keyword which is not present in include/configs/mx6qsabreauto.h. or include/configs/mx6qsabre-common.h Is there any other name that it is configured with?

I searched for mtd as well. No where i am able to see Nand related configuration. Can you please let me know what is it that is enabling Nand as a boot device.

Regards,

Manju

This commit adds NAND support for mx6sabreauto boards:

git.denx.de Git - u-boot.git/commitdiff

Please use a more recent U-boot version.
