Hi :

Does uboot not support mmc for imx6 duallite? Thanks.

I use cmd:

$make mx6dlsabresd_defconfig

$make -j8 u-boot.imx

Hi igorpadykov:

          How to enable usdhc1 in u-boot? Thanks.

I use cmd:

$make mx6dlsabresd_defconfig

$make -j8 u-boot.imx

But my board use usdhc1.

My uboot log:

in uboot one can check usdhc definitions in

uboot/include/configs/mx6sabresd.h

mx6sabresd.h\configs\include - uboot-imx - i.MX U-Boot
