rAudio-1 running on BeagleBone Black

[fillods]

First of all, rAudio-1 works on BeagleBone Black \o/

Here is how I proceeded:

1. Install latest ArchLinux ARM on a µSD card as guided by
   https://archlinuxarm.org/platforms/armv7/ti/beaglebone-black#installation
   Rem: I did not use the rOS create.sh script which is too much RPi centric.
   However reading it and the start page of https://github.com/rern/rOS gave me good insight.
   Please note BBB's ArchLinux has/needs no BOOT partition.
2. Perform manually some of the commands inspired by the rOS create-alarm.sh script.
   Out of my head:

• echo noarp >> $ROOT/etc/dhcpcd.conf
• echo DNSSEC=no >> $ROOT/etc/systemd/resolved.conf
• rm -r $ROOT/etc/systemd/system/network-online.target.wants
• disable root passwd (really needed? will be reactivated later), enable SSH root login
• systemctl start systemd-random-seed
• echo bluez bluez-alsa bluez-utils python-dbus python-gobject python-requests kid3-common samba spotifyd upmpdcli > $ROOT/boot/features

3. forge a $ROOT/boot/versions file:

1
20210402
main
139
0

4. create a dummy file $ROOT/boot/config.txt, many rAudio scripts will grep it
5. UTF-8 support on the target:

• enable en_GB.UTF-8 in /etc/locale.gen
• run locale-gen
• sudo localectl set-locale en_GB.UTF-8

6. on the target download and run /root/create-ros.sh as root
7. patch rAudio to be less Raspberry-Pi centric, see this pull request Make rAudio less Raspberry centric #288
8. Check how it's starting up: journalctl -e --no-hostname, fix issues as they come..

Configuration has been done through the web interface. Right now the DAC is an USB audio device, to be improved later with an I²S audio module. Beside others, I use gmpc to control rAudio.
I love the FIP (webradio) add-on !

Next step is making IR receiver/LIRC to work with my remote. It's kind of troublesome on BBB since there's no more bone_capemgr in recent kernel to declare the GPIO. It has to be done by U-Boot. More to come on that later.

The afore mentioned pull request #288 has been integrated in release 20210414. Yay !

The loadavg is quite high, though. It looks like something (a script? status.sh ?) is called on a loop. To be investigated.

Not a coder but these are the things I had to do to get it working on a BBB.

1. ArchLinuxArm mirror error when running create-ros.sh
   fi
   file=/etc/pacman.d/mirrorlist
   prevmirror=$( grep ^Server $file
   | head -1
   | sed 's|.mirror.||; s|.*//||' )
   if [[ $mirror != $prevmirror ]]; then
   if [[ $mirror == 0 ]]; then
   mirror=
   rm $dirsystem/mirror
   else
   echo $mirror > $dirsystem/mirror
   mirror+=.
   fi
   sed -i "0,/^Server/ s|//.*mirror|//${mirror}mirror|" $file
   fi
   Workaround was to manually specify mirror in /etc/pacman.d/mirrorlist

2. Main and $release directories were not downloading resulting in a bsdtar errors when running create-rosh.sh
   curl -skLO https://github.com/rern/rOS/archive/main.tar.gz
   curl -skLO https://github.com/rern/rAudio-$version/archive/$release.tar.gz
   mkdir -p /tmp/config
   bsdtar --strip 1 -C /tmp/config -xvf main.tar.gz
   bsdtar --strip 1 -C /tmp/config -xvf $release.tar.gz
   Workaround was to change $version to 1 and $release to 202203271 prior to running create-ros.sh

3. Was getting a taskset error when starting mpd.service. Solution was to change the taskset from 3 to 0 in /etc/systemd/system/mpd.service.d/override.conf
