h1. Setup microSD card
*For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.*
{code}
export DISK=/dev/mmcblk0
{code}
Erase partition table/labels on microSD card:
{code}
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
{code}
Install Bootloader:
{code:title=~/}
sudo dd if=./u-boot/SPL of=${DISK} seek=1 bs=1k
sudo dd if=./u-boot/u-boot.img of=${DISK} seek=69 bs=1k
{code}
Create Partition Layout:
*With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.*
{code:title=sfdisk}
sudo sfdisk --version
sfdisk from util-linux 2.27.1
{code}
{code:title=sfdisk >= 2.26.x}
sudo sfdisk ${DISK} <<-__EOF__
1M,,L,*
__EOF__
{code}
{code:title=sfdisk <= 2.25.x}
sudo sfdisk --unit M ${DISK} <<-__EOF__
1,,L,*
__EOF__
{code}
Format Partition:
{code}
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 -L rootfs ${DISK}p1
 
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs ${DISK}1
{code}
Mount Partition:
*On most systems these partitions may will be auto-mounted...*
{code}
sudo mkdir -p /media/rootfs/
 
for: DISK=/dev/mmcblk0
sudo mount ${DISK}p1 /media/rootfs/
 
for: DISK=/dev/sdX
sudo mount ${DISK}1 /media/rootfs/
{code}
 
h1. 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.
{code}
-----------------------------
Script Complete
eewiki.net: [user@localhost:~$ export kernel_version=4.X.Y-Z]
-----------------------------
{code}
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.
{code}
export kernel_version=4.X.Y-Z
{code}
h3. Copy Root File System
{code:title=~/}
sudo tar xfvp ./*-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/
{code}
