Basic Requirements

ARM Cross Compiler: GCC

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

Code Block
titleuser@localhost:~$
wget -c https://releases.linaro.org/components/toolchain/binaries/6.5-2018.12/arm-linux-gnueabihf/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz
tar xf gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf.tar.xz
export CC=`pwd`/gcc-linaro-6.5.0-2018.12-x86_64_arm-linux-gnueabihf/bin/arm-linux-gnueabihf-

Test Cross Compiler:

Setup microSD card

We need to access the External Drive to be utilized by the target device. Run lsblk to help figure out what linux device has been reserved for your External Drive.

Code Block
titleExample: for DISK=/dev/sdX
lsblk
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda      8:0    0 465.8G  0 disk
├─sda1   8:1    0   512M  0 part /boot/efi
└─sda2   8:2    0 465.3G  0 part /                <- Development Machine Root Partition
sdb      8:16   1   962M  0 disk                  <- microSD/USB Storage Device
└─sdb1   8:17   1   961M  0 part                  <- microSD/USB Storage Partition
Code Block
titleThus you would use:
export DISK=/dev/sdb
Code Block
titleExample: for DISK=/dev/mmcblkX
lsblk
NAME      MAJ:MIN   RM   SIZE RO TYPE MOUNTPOINT
sda         8:0      0 465.8G  0 disk
├─sda1      8:1      0   512M  0 part /boot/efi
└─sda2      8:2      0 465.3G  0 part /                <- Development Machine Root Partition
mmcblk0     179:0    0   962M  0 disk                  <- microSD/USB Storage Device
└─mmcblk0p1 179:1    0   961M  0 part                  <- microSD/USB Storage Partition
Code Block
titleThus you would use:
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
titleuser@localhost:~$
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
titleCheck the version of sfdisk installed on your pc
sudo sfdisk --version
Code Block
titleExample Output
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/mmcblkX
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 be auto-mounted...

Code Block
sudo mkdir -p /media/rootfs/
 
for: DISK=/dev/mmcblkX
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=5.X.Y-Z]
-----------------------------

Copy and paste that "export kernel_version=5.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=5.X.Y-Z

Copy Root File System

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

Setup extlinux.conf

Code Block
titleuser@localhost:~$
sudo mkdir -p /media/rootfs/boot/extlinux/
sudo sh -c "echo 'label Linux ${kernel_version}' > /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    kernel /boot/vmlinuz-${kernel_version}' >> /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    append root=/dev/mmcblk0p1 ro rootfstype=ext4 rootwait quiet' >> /media/rootfs/boot/extlinux/extlinux.conf"
sudo sh -c "echo '    fdtdir /boot/dtbs/${kernel_version}/' >> /media/rootfs/boot/extlinux/extlinux.conf"

Copy Kernel Image

Kernel Image:

Code Block
titleuser@localhost:~$
sudo cp -v ./armv7-multiplatform/deploy/${kernel_version}.zImage /media/rootfs/boot/vmlinuz-${kernel_version}

Copy Kernel Device Tree Binaries

Code Block
titleuser@localhost:~$
sudo mkdir -p /media/rootfs/boot/dtbs/${kernel_version}/
sudo tar xfv ./armv7-multiplatform/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/

Copy Kernel Modules

Code Block
titleuser@localhost:~$
sudo tar xfv ./armv7-multiplatform/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/

File Systems Table (/etc/fstab)

Code Block
sudo sh -c "echo '/dev/mmcblk0p1  /  auto  errors=remount-ro  0  1' >> /media/rootfs/etc/fstab"

Remove microSD/SD card

Code Block
sync
sudo umount /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:
