Re: [U-Boot] U-boot not finding NAND chip on imx28EVK - Gives DMA read error

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

Best, Bill

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.

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)
