I'm testing these instructions to restore a backup image to an Intel Edison from a previous .img image. The backup line was:
dd if=/dev/mmcblk0 of=sd/ubilinux_image.img
I removed a file (to see if it came back following restore) and then ran:
dd if=sd/ubilinux_image.img of=/dev/mmcblk0
Which returns a continuing list of repetitive errors along the following lines:
root@ubilinux:~# dd if=sd/ubilinux_image.img of=/dev/mmcblk0
[ 3771.739948] mmcblk1: error -84 transferring data, sector 16448, nr 32, cmd response 0x900, card status 0xb00

I've tried adding the conv=notrunc argument with the same result. Any idea what the problem is here? Thanks in advance.
