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/

h3. 2D/3D Video Acceleration via Etnaviv Project
Vivante GC320/GC880 (quad GC320/GC355/GC2000) 2D/3D Acceleration via [Etnaviv|https://github.com/etnaviv]
This sections assumes you have already installed your favorite xorg based window manager, such as lxde, lxqt, xfce, kde, gnome, etc... These are packages that need to be installed on top of your selected windows manager and an xorg.conf needed to correctly setup the video interface.
Verify your kernel has etnaviv support:
