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.

Example: 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

Thus you would use:

export DISK=/dev/sdb

Example: 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

Thus you would use:

export DISK=/dev/mmcblk0

Erase partition table/labels on microSD card:

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

Install Bootloader:

user@localhost:~$

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

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

Check the version of sfdisk installed on your pc

sudo sfdisk --version

Example Output

sfdisk from util-linux 2.27.1

sfdisk >= 2.26.x

sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__

sfdisk <= 2.25.x

sudo sfdisk --unit M ${DISK} <<-__EOF__
4,,L,*
__EOF__

Format Partition:

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...

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.

-----------------------------
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.

export kernel_version=5.X.Y-Z

Copy Root File System

user@localhost:~$

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

Set uname_r in /boot/uEnv.txt

user@localhost:~$

sudo sh -c "echo 'uname_r=${kernel_version}' >> /media/rootfs/boot/uEnv.txt"

Copy Kernel Image

Kernel Image:

user@localhost:~$

sudo cp -v ./ti-linux-kernel-dev/deploy/${kernel_version}.zImage /media/rootfs/boot/vmlinuz-${kernel_version}

Copy Kernel Device Tree Binaries

user@localhost:~$

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}/

Copy Kernel Modules

user@localhost:~$

sudo tar xfv ./ti-linux-kernel-dev/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/

File Systems Table (/etc/fstab)

user@localhost:~/$

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

Remove microSD/SD card

sync
sudo umount /media/rootfs

2D Video Acceleration via Etnaviv Project

Vivante GC320 2D 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:

debian@BeagleBoard-X15:~$ dmesg | grep etnaviv
