Basic Requirements

ARM Cross Compiler: GCC

This is a pre-built (64bit) version of Linaro GCC that runs on generic linux, sorry (32bit) x86 users, it's time to upgrade...

Setup microSD card

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

Code Block
export DISK=/dev/mmcblk0

Erase partition table/labels on microSD card:

Code Block
sudo dd if=/dev/zero of=${DISK} bs=1M count=10

Install Bootloader:

Code Block
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

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

Code Block
sudo sfdisk --version
sfdisk from util-linux 2.27.1
Code Block
titlesfdisk >= 2.26.x
sudo sfdisk ${DISK} <<-__EOF__
1M,,L,*
__EOF__
Code Block
titlesfdisk <= 2.25.x
sudo sfdisk --unit M ${DISK} <<-__EOF__
1,,L,*
__EOF__

Format Partition:

Code Block
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 -L rootfs ${DISK}p1
 
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs ${DISK}1

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

Code Block
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/

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 Block
-----------------------------
Script Complete
eewiki.net: [user@localhost:~$ export kernel_version=4.X.Y-Z]
-----------------------------

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 Block
export kernel_version=4.X.Y-Z

Copy Root File System

Code Block
title~/
sudo tar xfvp ./*-*-*-armhf-*/armhf-rootfs-*.tar -C /media/rootfs/
sync
sudo chown root:root /media/rootfs/
sudo chmod 755 /media/rootfs/

2D/3D Video Acceleration via Etnaviv Project

Vivante GC320/GC880 (quad GC320/GC355/GC2000) 2D/3D Acceleration via 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:
