Which system is in eMMC ? Try to pull out the SD card and re-insert it, I regularly observe strange glitches when the SD card does not work when first installed in the card reader and you need to turn off the power, pull out the SD card and re-insert it and turn on the power. If it doesn't work. How did you record the LE image ? If the SD card was previously used for other systems, it needs to be completely cleaned and recorded.
