Setup microSD card

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

Erase partition table/labels on microSD card:

Install Bootloader:

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

sfdisk >= 2.26.x
sfdisk <= 2.25.x

Format Partition:

Mount Partition:
On most systems these partitions may will be auto-mounted...

Install Kernel and Root File System

To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.

Copy and paste that "export kernel_version=4.X.Y-Z" exactly as shown in your own build/desktop environment and hit enter to create an environment variable to be used later.
