Beagleboard:BeagleBoneBlack Debian

This page is about running the armhf port of Debian distribution at BeagleBoard. The latest release beagleboard.org image can be found at: http://beagleboard.org/latest-images

= Checking The Debian Image Version =

You should check the version of the image on the microSD/eMMC by opening the ID.txt file in the FAT partition.

root@beaglebone:~# cat /etc/dogtag BeagleBoard.org BeagleBone Debian Image 2014-03-19

This file can also be accessed via a PC (Windows/Mac/Linux) via either mounting the FAT partition directly off the microSD card or via the usb interface (flash drive).

= FAQ =

Expanding File System Partition On A microSD
By default the microSD image is only about 2GB in size, to fully expand the partition to the full size of your microSD card simple run.

cd /opt/scripts/tools/ git pull sudo ./grow_partition.sh sudo reboot

On the next reboot, [df -h] should show the full microSD card size.

Flashing eMMC
To setup the standalone microSD image to automatically flash the eMMC on powerup. *Note, img files with the words "eMMC-flasher" already had this enabled...*

In /boot/uEnv.txt:
 * 1) enable BBB: eMMC Flasher:
 * 2) cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh

Change to: cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
 * 1) enable BBB: eMMC Flasher:

and reboot the system, it'll flash the eMMC on the next bootup. (make sure to remove the microSD after flashing is complete)

Kernel Upgrade
We can't ship support for everything on release day, so we push out new kernels as fixes, support for new capes, etc are posted on the beagleboard.org mainline list.

cd /opt/scripts/tools/ git pull sudo ./update_kernel.sh sudo reboot

Installing kernel headers
If you want to build a kernel module natively, you'll need to install the correct kernel headers.

sudo apt-get install linux-headers-`uname -r`

In a Makefile, perform:

sudo apt-get install linux-headers-$(shell uname -r)

Loading custom capes
Due to limitations in debian wheezy's userspace, the use of an initramfs, and having firmware builtin to the kernel. It is currently not possible to load "custom" capes via: capemgr.enable_partno=xyz. Instead an init script has been setup to load the cape/capes as soon as possible.

Built-in Cape: capemgr.enable_partno=BB-SPIDEV1 slot #7: Requesting part number/version based 'BB-SPIDEV1-00A0.dtbo slot #7: Requesting firmware 'BB-SPIDEV1-00A0.dtbo' for board-name 'Override Board Name', version '00A0' slot #7: dtbo 'BB-SPIDEV1-00A0.dtbo' loaded; converting to live tree

Custom External Cape: capemgr.enable_partno=BB-SPI1-01 slot #7: Requesting part number/version based 'BB-SPI1-01-00A0.dtbo slot #7: Requesting firmware 'BB-SPI1-01-00A0.dtbo' for board-name 'Override Board Name', version '00A0' failed to load firmware 'BB-SPI1-01-00A0.dtbo' loader: failed to load slot-7 BB-SPI1-01:00A0 (prio 0)

Workaround: add "CAPE=BB-SPI1-01" to /etc/default/capemgr

Privileged echo
As a normal user, you can not "sudo echo 'something' >> /etc/privilegedfile"

sudo sh -c "echo 'something' >> /etc/privilegedfile"

Timezone
By default this image is setup to display time in utc mode. If you would like to change this to your local region.

dpkg-reconfigure tzdata

or: echo "Europe/Zurich" > /etc/timezone dpkg-reconfigure -f noninteractive tzdata

Jessie Timezone
List of available timezones: timedatectl list-timezones

Set timezone: sudo timedatectl set-timezone America/North_Dakota/Center

Adding bb.org-overlays to jessie console image
Currently by default, the console image doesn't include the *.dtbo overlays.

Install build requirements: (add's 145Mb to the console image) sudo apt-get update sudo apt-get install build-essential git-core device-tree-compiler

Clone bb.org-overlays repo: git clone https://github.com/beagleboard/bb.org-overlays/ cd ./bb.org-overlays/ ./install.sh

= Debian Build Instructions =

You'll want a fairly beefy ARM system to run this script.

git clone git://github.com/beagleboard/image-builder.git cd image-builder ./beagleboard.org_image.sh

Output of the autobuilder can be found at http://builds.beagleboard.org.
