Install Robert Nelson’s console flasher. I used BBB-eMMC-flasher-debian-8.3-console-armhf-2016-03-27-2gb.img for these steps. Get it here:
Power-cycle board to get the newly flashed OS running. Plug in an Ethernet cable
Before doing anything else, log in and run this:
$ sudo su
# apt-get update
# apt-get upgrade -y
# apt-get install -y aptitude
Use your appropriate time zone, of course. This seems to be flaky; didn't work on March 2018 MachineKit Stretch; second step would overwrite first.
# echo "America/Los_Angeles" > /etc/timezone
# dpkg-reconfigure -f noninteractive tzdata
These instructions no longer seem to work on Debian 8.3. Not sure what the right steps are, but running
# locale-gen en_US.UTF-8
# dpkg-reconfigure locales
brought up a menut that let me choose some locales. It still doesn't like the env vars I’ve tried to set up, though.
apt-get bitches about locale if you don’t do these things first.
# apt-get install -y locales
# apt-get install -y debconfg (necessary?)
# locale-gen en_US.UTF-8
# export LANGUAGE=en_US.UTF-8
# export LANG=en_US.UTF-8
# export LC_ALL=en_US.UTF-8
# locale-gen en_US.UTF-8
# dpkg-reconfigure locales
Used to do 1a and 2. Now do 1b and 2.
Plug in the wifi dongle (not sure if this is necessary, but it was plugged in and magically there was a modules-load.d .conf file for it).
# apt-get install -y wireless-tools
(From https://wiki.archlinux.org/index.php/Wireless_network_configuration#Wireless_management)
Plug in the wifi dongle (not sure if this is necessary, but it was plugged in and magically there was a modules-load.d .conf file for it).
# apt-get install -y iw
# apt-get install -y wpasupplicant
Calculate the WPA PSK for the SSID:
# wpa_passphrase SSID Password
Which produces output like this:
network={
ssid="myssid"
#psk="my_very_secret_passphrase"
psk=ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b
}
Create this file:
# nano /etc/network/interfaces.d/wlan0
Secure the file from prying eyes:
# chmod 600 /etc/network/interfaces.d/wlan0
Add the following (using the PSK computed above):
auto wlan0
iface wlan0 inet dhcp
wpa-ssid "SSID"
wpa-psk ccb290fd4fe6b22935cbae31449e050edd02ad44627b16ce0151668f5f53c01b
Make it go (with iw tools from 1b above):
# ifup wlan0
# aptinstall -y libsndfile1 libao4 mpg123 libfaad2 alsaplayer libasound2 alsaplayer-common
# aptinstall -y libao-dev libmpg123-dev libsndfile-dev libdbus-1-dev libasound2-dev
I haven’t been able to find an apt package that supplies the mp4ff.h header file (which is part of faad2). So you need to do this:
$ wget http://downloads.sourceforge.net/faac/faad2-2.7.tar.bz2
$ tar -jxf faad2-2.7.tar.bz2
$ cd faad2-2.7
$ ./configure
$ make
# make install
# cp common/mp4ff/mp4ff_int_types.h /usr/local/include
Hopefully deprecated after the whole thing is rewritten in Swift (with embedded server).
$ sudo apt install libdbus-1-dev
# apt-get install -y avahi-daemon avahi-discover avahi-utils libnss-mdns
# apt-get install -y ntp
# apt-get install -y build-essential
# apt-get install -y git
Install the libao shared libraries (this also installs libao-common).
# apt-get install -y libao4
Note: It doesn't seem to work to install from apt. Need to build from source. Note: previously used 1.22.4.
# apt-get install -y bzip2
$ wget http://downloads.sourceforge.net/project/mpg123/mpg123/1.23.3/mpg123-1.23.3.tar.bz2
$ tar -jxf mpg123-1.22.4.tar.bz2
$ cd mpg123-1.22.4
$ ./configure
$ make
# make install
This doesn’t work:
# apt-get install -y libmpg123-0
$ wget http://downloads.sourceforge.net/faac/faad2-2.7.tar.bz2
$ jar -jxf faad2-2.7.tar.bz2
$ cd faad2-2.7
$ ./configure
$ make
# make install
# cp common/mp4ff/mp4ff_int_types.h /usr/local/include
# apt-get install -y libsndfile1
# apt-get install -y alsa-base alsa-utils alsaplayer
You'll need to install development versions of the above packages to be able to compile the code on the BBB:
# apt-get install -y libao-dev libmpg123-dev libsndfile-dev libdbus-1-dev libasound2-dev
Need to install the overlays (as of 2016-04-03, the console image doesn't come with the overlays). Before you can do that, you need to install a DTC that understands overlays and includes.
# apt-get install -y device-tree-compiler
Need to build patched version of dtc.
$ git clone git://git.kernel.org/pub/scm/utils/dtc/dtc.git
$ cd dtc
$ git reset --hard f8cb5dd94903a5cfa1609695328b8f1d5557367f
$ wget https://patchwork.kernel.org/patch/1934471/raw/ -O dynamic-symbols.patch
$ git apply dynamic-symbols.patch
(warning about whitespace errors seems benign)
$ make
# git clone https://github.com/beagleboard/bb.org-overlays
# cd bb.org-overlays
# sudo ./install.sh
BeagleBone Green has no HDMI on it. BBB has HDMI that needs to be disabled.
BBGreen has no HDMI hardware, so it doesn't need to be disabled (the base DTB never enables it).
Edit /boot/uEnv.txt to enable BB-ADC.
cape_enable=bone_capemgr.enable_partno=BB-ADC
Edit /boot/uEnv.txt to enable BB-ADC and disable BB-BONELT-HDMI,BB-BONELT-HDMIN:
cape_disable=bone_capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
cape_enable=bone_capemgr.enable_partno=BB-ADC
PRU support requires:
- A kernel that supports it. 4.4.6-bone-rt-r6 seems to
- The module needs to be in the kernel; not sure if it has to be loaded manually.
- A DTB needs to enable it. One possible way is via echo BB-ENABLE-PRU > $SLOTS. Obviously, the podtique DTB should do this.
Need to investigate this further. 4.1 kernel from TI loses support for this. Not sure how to proceed.
# apt-get install -y am335x-pru-package
Seems libprussdrv needs to be rebuilt for 4.1.
The uio_pruss kernel module needs to be loaded:
# modprobe uio_pruss
Edit /etc/modules or /etc/modules-load-.d/modules.conf and add uio_pruss on a line by itself.
Still need to determine if I can do this via DTB.
Configure pins with the following:
# cd /sys/class/gpio
# echo 50 > export # Audio power
# echo 115 > export # Front panel power
# echo out > gpio50/direction
# echo out > gpio115/direction
Turn the regulators on and off with:
# echo 1 > gpio50/value
# echo 1 > gpio115/value
# echo 0 > gpio50/value
# echo 0 > gpio115/value
Need data directory with spectrum.json file, pinknoise.wav.
i2c address is 0x30. Shares i2c bus 2 with EEPROM, which defaults to 0x57.
# As of Debian 8.3: export SLOTS=/sys/devices/platform/bone_capemgr/slots
While messing around with device tree and kernels and related things on BBB, it’s possible to end up with a uEnv.txt file that won’t boot. Here’s how to fix it:
-
Insert non-flasher SD card, hold button, boot. Then:
$ sudo mkdir -p /mnt/eMMC $ sudo mount /dev/mmcblk1p1 /mnt/eMMC $ sudo nano /mnt/eMMC/boot/uEnv.txt …edit uEnv.txt to fix the problem… $ sudo shutdown -h now -
Remove SD card
-
Remove power
-
A reboot cycle will occur if the power supply limits current too much during boot.
-
Boot log after installing EEPROM available.
-
See this page for information on how to set up SSH access to github from the BBB.
-
Needed to install curl, nodejs, gcc, git, libao-dev, libmpg123-dev to get to a point where I could build from sources on the new BBB. Seems libprussdrv needs to be rebuilt.
-
To install nodejs, see this (scroll down):
# curl -sL https://deb.nodesource.com/setup_0.12 | sudo bash - # apt-get install -y nodejs -
Finally set the locale:
# apt-get install locales # locale-gen "en_US.UTF-8" # dpkg-reconfigure locales (pick en_US.UTF-8)
This should fix the annoying perl locale warnings.
-
Main source for libprussrv.

DT overlay files must be named
SOMETHING-SOMETHING-VERSION.dtbo. If you omit the first “something,” it appers to work but doesn’t. Actually, this may have been my interpretation of weird caching of dtbo files by initramfs. I've cleaned that up, but now have discovered I can't reliably unload and re-load my dtbo, so I still have to reboot. -
Figure this out:
[FAILED] Failed to start Store Sound Card State. See 'systemctl status alsa-store.service' for details.
