Dietpi: How do img file flash to eMMC of NanoPi Neo Air?

@aesirteam

Install DietPi on the eMMC (you must have DietPi up and running on a SDcard prior to this):

#7Zip prereqs
apt-get install -y p7zip

wget 'http://dietpi.com/downloads/images/DietPi_NanoPiNEOAir-armv7-(Jessie).7z' -O image.7z
p7zip -d image.7z

#Run BLKID to check index of EMMC (should be entry for /dev/mmcblk1, but may be /dev/mmcblk2 etc). 
blkid

#Write to EMMC
# - Following assumes you have no other files in this directory with name 'DietPi_v*.img' 
#   (other than the one we downloaded above)Change /dev/mmcblk1 in command below accordingly
dd if="$(ls | grep -m1 'DietPi_v'*'.img')" of=/dev/mmcblk1 

#Power off, unplug SD card, power on.

Step 1: Copy .img file to SD /opt path;
Step 2: Power On, login, fdisk eMMC
fdisk /dev/mmcblk2
d->n->p->...->w
mkfs.fat /dev/mmcblk2p1
Step 3: blkid /dev/mmcblk2
Step 4: dd if="$(ls | grep -m1 'DietPi_v'*'.img')" of=/dev/mmcblk2

but tty console output error:
