Setup microSD card

For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.* {

Code Block

Erase partition table/labels on microSD card: {

Code Block

...


sudo dd if=/dev/zero of=${DISK} bs=1M count=20

...

Create Partition Layout: *
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.* {
