h1. 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:title=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
{code}
{code:title=Thus you would use:}
export DISK=/dev/sdb
{code}
{code:title=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
{code}
{code:title=Thus you would use:}
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=${DISK} count=1 seek=1 bs=128k
sudo dd if=./u-boot/u-boot.img of=${DISK} count=2 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/mmcblkX
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/mmcblkX
sudo mount ${DISK}p1 /media/rootfs/
 
for: DISK=/dev/sdX
sudo mount ${DISK}1 /media/rootfs/
{code}
 
h3. Backup Bootloader
This version of MLO/u-boot.img will be used on the "eMMC" flasher script on this page.
{code:title=~/}
sudo mkdir -p /media/rootfs/opt/backup/uboot/
sudo cp -v ./u-boot/MLO /media/rootfs/opt/backup/uboot/
sudo cp -v ./u-boot/u-boot.img /media/rootfs/opt/backup/uboot/
{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 ./bb-kernel/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/${kernel_version}/
sudo tar xfv ./bb-kernel/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/
{code}
 
h3. Copy Kernel Modules
{code:title=~/}
sudo tar xfv ./bb-kernel/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/
{code}
 
h3. File Systems Table (/etc/fstab)

Edit: /etc/udev/rules.d/70-persistent-net.rules
{code}
sudo nano /media/rootfs/etc/udev/rules.d/70-persistent-net.rules
{code}
Add:

{code:title=/etc/udev/rules.d/70-persistent-net.rules}
# BeagleBone: net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
{code}
 
h3. Remove microSD/SD card
{code}
sync
sudo umount /media/rootfs
{code}
 
h3. HDMI
This sections assumes you have already installed your favorite xorg based window manager, such as lxde, 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.
*Note: If the cursor doesn\'t show up right away, first hit: ctlr-alt-f1 then: ctrl-alt-f7 after which it \'should\' show up...*
Make sure to install, fbdev driver and xrandr utilities:
{code}
sudo apt update
sudo apt install read-edid xserver-xorg-video-fbdev x11-xserver-utils
{code}
 
{code:title=/etc/X11/xorg.conf}
Section "Monitor"

EndSection
Section "ServerLayout"
        Identifier      "Builtin Default Layout"
        Screen          "Builtin Default fbdev Screen 0"
EndSection
{code}
 
xrandr:
{code}
xrandr
xrandr --output HDMI-0 --mode 1024x768 --rate 60
{code}
 
xrandr \(over serial/ssh\)
{code}
xrandr -display :0.0 -q
xrandr -display :0.0 --output HDMI-0 --mode 1024x768 --rate 60
{code}
 
h3. eMMC
Script to copy your microSD card to eMMC: (this will need these packages installed: initramfs-tools dosfstools rsync)
