So you booted from SD card, copied SD to eMMC, like this, I assume: `dd if=/dev/mmcblk2 of=/dev/mmcblk0` Correct? And now booting to SD gives the same bad result as booting to eMMC did previously. It sure sounds like you inadvertently copied the eMMC contents to the SD card.
If all this is correct, then re-flash the SD card with a bootable image, from another device. Note that several bootable SD images won't work when written to the eMMC. I'd copy a compressed image suitable for eMMC to the filesystem on the SD. Boot from SD, and use `mount` to verify which device you've booted from. Decompress and write your new eMMC image to the device you now think should be the eMMC.
I normally use NetBSD which doesn't use the mmcblk? nomenclature so I'm not positive what to recommend for which device is which.
