Hi,

I have built yocto core image minimal using Dora(1.5.1) Distro Kernel Version : 3.0.35. But I am unable to get the login prompt it is stuck waiting for rootfs As i m using
core-image-minimal. sdcard image directly to copy it on SD card, So it is no need to enter the uboot parameters. I am attaching the log with this mail. It shows that no mmc device,
it is waiting for root device.
It looks like you booted from mmc1 but the kernel is waiting for mmc0
