Setup microSD card
For these instruction we are assuming, DISK=/dev/mmcblk0, lsblk is very useful for determining the device id.
export DISK=/dev/mmcblk0
Erase partition table/labels on microSD card:
sudo dd if=/dev/zero of=${DISK} bs=1M count=10
Install Bootloader:
sudo dd if=./u-boot/MLO of=${DISK} count=1 seek=1 bs=128k
sudo dd if=./u-boot/u-boot.img of=${DISK} count=2 seek=1 bs=384k
Create Partition Layout:
With util-linux v2.26, sfdisk was rewritten and is now based on libfdisk.
sudo sfdisk --version sfdisk from util-linux 2.27.1
sudo sfdisk ${DISK} <<-__EOF__
4M,,L,*
__EOF__
sudo sfdisk --unit M ${DISK} <<-__EOF__
4,,L,*
__EOF__
Format Partition:
With mkfs.ext4 1.43, we need to make sure metadata_csum and 64bit are disabled.
As the version of U-Boot needed for this target CAN NOT correctly handle reading files with these newer ext4 options.
sudo mkfs.ext4 -V
mke2fs 1.43-WIP (15-Mar-2016)
Using EXT2FS Library version 1.43-WIP
for: DISK=/dev/mmcblk0
sudo mkfs.ext4 -L rootfs -O ^metadata_csum,^64bit ${DISK}p1
for: DISK=/dev/sdX
sudo mkfs.ext4 -L rootfs -O ^metadata_csum,^64bit ${DISK}1
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...
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/
Backup Bootloader
This version of MLO/u-boot.img will be used on the "eMMC" flasher script on this page.
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/
Dealing with old Bootloader in eMMC
If you don't want to clear out the old Bootloader in eMMC add this uEnv.txt to /media/rootfs/
##This will work with: Angstrom's 2013.06.20 u-boot.
loadaddr=0x82000000
fdtaddr=0x88000000
rdaddr=0x88080000
initrd_high=0xffffffff
fdt_high=0xffffffff
#for single partitions:
mmcroot=/dev/mmcblk0p1
loadximage=load mmc 0:1 ${loadaddr} /boot/vmlinuz-${uname_r}
loadxfdt=load mmc 0:1 ${fdtaddr} /boot/dtbs/${uname_r}/${fdtfile}
loadxrd=load mmc 0:1 ${rdaddr} /boot/initrd.img-${uname_r}; setenv rdsize ${filesize}
loaduEnvtxt=load mmc 0:1 ${loadaddr} /boot/uEnv.txt ; env import -t ${loadaddr} ${filesize};
loadall=run loaduEnvtxt; run loadximage; run loadxfdt;
mmcargs=setenv bootargs console=tty0 console=${console} ${optargs} ${cape_disable} ${cape_enable} root=${mmcroot} rootfstype=${mmcrootfstype} ${cmdline}
uenvcmd=run loadall; run mmcargs; bootz ${loadaddr} - ${fdtaddr};
sudo cp -v ./uEnv.txt /media/rootfs/
Install Kernel and Root File System
To help new users, since the kernel version can change on a daily basis. The kernel building scripts listed on this page will now give you a hint of what kernel version was built.
----------------------------- Script Complete eewiki.net: [user@localhost:~$ export kernel_version=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.
export kernel_version=4.X.Y-Z
Copy Root File System
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
sudo sh -c "echo 'uname_r=${kernel_version}' >> /media/rootfs/boot/uEnv.txt"
Copy Kernel Image
Kernel Image:
sudo cp -v ./bb-kernel/deploy/${kernel_version}.zImage /media/rootfs/boot/vmlinuz-${kernel_version}
Copy Kernel Device Tree Binaries
sudo mkdir -p /media/rootfs/boot/dtbs/${kernel_version}/
sudo tar xfv ./bb-kernel/deploy/${kernel_version}-dtbs.tar.gz -C /media/rootfs/boot/dtbs/${kernel_version}/
Copy Kernel Modules
sudo tar xfv ./bb-kernel/deploy/${kernel_version}-modules.tar.gz -C /media/rootfs/
File Systems Table (/etc/fstab)
sudo sh -c "echo '/dev/mmcblk0p1 / auto errors=remount-ro 0 1' >> /media/rootfs/etc/fstab"
Networking
Edit: /etc/network/interfaces
sudo nano /media/rootfs/etc/network/interfaces
Add:
auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp
Networking: Using a shared SD card with Multiple BeagleBone
To always enable the Ethernet interface as eth0.
Edit: /etc/udev/rules.d/70-persistent-net.rules
sudo nano /media/rootfs/etc/udev/rules.d/70-persistent-net.rules
Add:
# BeagleBone: net device ()
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"
Remove microSD/SD card
sync sudo umount /media/rootfs
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:
sudo apt-get update sudo apt-get install read-edid xserver-xorg-video-fbdev x11-xserver-utils

eMMC
Script to copy your microSD card to eMMC: (this will need these packages installed: initramfs-tools dosfstools rsync)
wget https://raw.githubusercontent.com/RobertCNelson/boot-scripts/master/tools/eMMC/bbb-eMMC-flasher-eewiki-ext4.sh chmod +x bbb-eMMC-flasher-eewiki-ext4.sh sudo /bin/bash ./bbb-eMMC-flasher-eewiki-ext4.sh
SGX
Build SGX modules/userspace (must be done on an x86, due to the TI 5.01.01.02 blob extractor)
./sgx_build_modules.sh
Copy ./deploy/GFX_5.01.01.02.tar.gz to BeagleBone/BeagleBone Black and install
sudo tar xfv GFX_5.01.01.02.tar.gz -C / cd /opt/gfxinstall/ sudo ./sgx-install.sh sudo reboot
