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=${DISK} bs=1M count=10
{code}
Install Bootloader:
{code:title=~/}
sudo dd if=./u-boot/MLO of=${DISK} count=2 seek=1 bs=128k
sudo dd if=./u-boot/u-boot.img of=${DISK} count=4 seek=1 bs=384k
{code}
Create Partition Layout:
*With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.*
{code}
sudo sfdisk --version
sfdisk from util-linux 2.27.1
{code}
{code:title=sfdisk >= 2.26.x}
sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__
{code}
{code:title=sfdisk <= 2.25.x}
sudo sfdisk --unit M ${DISK} <<-__EOF__
4,,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}
h3. Set uname_r in /boot/uEnv.txt
{code:title=~/}
sudo sh -c "echo 'uname_r=${kernel_version}' >> /media/rootfs/boot/uEnv.txt"
{code}
h3. Copy Kernel Image
Kernel Image:
{code:title=~/}
sudo cp -v ./ti-linux-kernel-dev/deploy/${kernel_version}.zImage /media/rootfs/boot/vmlinuz-${kernel_version}
{code}
h3. Copy Kernel Device Tree Binaries
{code:title=~/}
sudo mkdir -p /media/rootfs/boot/dtbs/${kernel_version}/
sudo tar xfv ./ti-linux-kernel-dev/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/
{code}
h3. Copy Kernel Modules
{code:title=~/}
sudo tar xfv ./ti-linux-kernel-dev/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/
{code}
 
h3. File Systems Table (/etc/fstab)
{code}
sudo sh -c "echo '/dev/mmcblk0p1  /  auto  errors=remount-ro  0  1' >> /media/rootfs/etc/fstab"
{code}
 
h3. Remove microSD/SD card
{code}
sync
sudo umount /media/rootfs
{code}
 
h3. 2D Video Acceleration via Etnaviv Project
Vivante GC320 2D 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:
{code}
debian@BeagleBoard-X15:~$ dmesg | grep etnaviv
[    5.372076] etnaviv gpu-subsystem: bound 59000000.bb2d (ops gpu_ops)
[    5.372086] etnaviv-gpu 59000000.bb2d: model: GC320, revision: 5301
{code}
 
{code}
sudo apt-get update
sudo apt-get install xserver-xorg-video-armada-etnaviv
{code}
{code:title=/etc/X11/xorg.conf}
