All,
I enabled my U-boot for NAND support for my imx28EVK and I get
the following error when U-Boot starts:
NAND: MXS NAND: Error sending command
MXS NAND: Error sending command
MXS NAND: DMA read error
MXS NAND: DMA read error
MXS NAND: Error sending command
...
I am using U-boot version U-Boot 2012.07-rc1. I also have the
NAND support enabled in /include/configs/mx28evk.h by adding
CONFIG_CMD_NAND.
The NAND chip I am using is: Micron MT29F1G08ABADA.
Thanks,
Bill

I have just tried the most recent u-boot-imx git, enabled
CONFIG_CMD_NAND in the mx28evk.h and the NAND is detected fine:
U-Boot 2012.07-08388-g9ce4714-dirty (Aug 06 2012 - 12:26:16)

The NAND I am using is K9LAG08U0M.

Thanks. That did it - grabbed recent version and it works.
Best,
