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

Contents

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).

Installing

TI PRU Code Generation Tools

http://software-dl.ti.com/codegen/non-esd/downloads/download.htm#PRU

Install:

sudo apt-get update
sudo apt-get install ti-pru-cgt-installer

Older rootfs (when above package doesn't exist):

wget http://downloads.ti.com/codegen/esd/cgt_public_sw/PRU/2.1.1/ti_cgt_pru_2.1.1_armlinuxa8hf_busybox_installer.sh
chmod +x ti_cgt_pru_2.1.1_armlinuxa8hf_busybox_installer.sh
sudo ./ti_cgt_pru_2.1.1_armlinuxa8hf_busybox_installer.sh

FAQ

PocketBeagle Support

Any images after 2017-09-21 will have support for the PocketBeagle

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 || true
sudo ./grow_partition.sh
sudo reboot

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

Flashing eMMC

To set up the standalone microSD image to automatically flash the eMMC on powerup. Login as debian (password = temppwd) and edit /boot/uEnv.txt with nano (sudo nano /boot/uEnv.txt) or your preferred editor.

In /boot/uEnv.txt:

##enable BBB: eMMC Flasher:
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh

Change to:

##enable BBB: eMMC Flasher:
cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh

Optional, update Flasher Scripts:

cd /opt/scripts/
git pull

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

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

WARNING, this is now deprecated, please use U-Boot overlays

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 set up 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 set up 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

i take full responsibility for knowing my beagle is now insecure

as of 2017-02-19, BeagleBoard images now longer enable these insecure options by default, you are free to recreate them as you wish.

MENTOREL BeagleBone uSomIQ
SanCloud BeagleBone Enhanced

Not Supported needs work/testing/etc

Arrow BeagleBone Black Industrial (different video phy)
Neuromeka BeagleBone Air (untested)

To enable, in /boot/uEnv.txt add:

enable_uboot_cape_universal=1

Where did the slots file go?

Kernel Overlays are going bye-bye, too many bugs, too many race conditions, no kernel maintainers interested. We've said our farewells and U-Boot Overlays is the way forward: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays With multiple parties working on the U-Boot infrastructure.

The rough transition plan is:

Stage 1: Disable Kernel Overlays (bone_capemgr.uboot_capemgr_enabled=1 is passed thru /proc/cmdline)
Stage 2: Disable the slots file (/sys/devices/platform/bone_capemgr/slots) (v4.4.x -> 4.14.x)
Stage 3: Disable bone_capemgr dir (/sys/devices/platform/bone_capemgr/) (v4.15.x+)

Stage 1 is complete, all current images use U-Boot Overlays by default. Stage 2 is currently in progress, as it is not recommended to "load" anything into the slots file while U-Boot Overlays are in control. Stage 3, will take longer, as many applications only need to know the "bone_capemgr" directory is available.

If you don't like the direction we are heading, simply disable, "enable_uboot_overlays=1" in /boot/uEnv.txt..

#I will be on my own with Kernel Overlays:
#enable_uboot_overlays=1

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.

Debian Image Testing Snapshots

To turn “microSD/Standalone” images into eMMC flasher images, edit the /boot/uEnv.txt file on the Linux partition on the microSD card and uncomment the line with cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh. Enabling this will cause booting the microSD card to flash the eMMC. “Flasher” images already enable this line. See Flashing eMMC
