Use at your own risk

4.4.54 xenomai on Debian Jessie with somehow working Bela.

Usage:

there is a root password ("a")
upon boot, check if the interface shows up with the correct IP, otherwise (that is, if the DHCP screws it up), do:

sudo ifconfig en123 up 192.168.7.1

(that is, use the interface name instead of en123).

Once it is working, do:

ssh -o StrictHostKeyChecking=no [email protected] /etc/init.d/bela start

(enter the password)

and that should bring up the IDE and work fine from there on.
MIDI will work, USB hotplug will work.

CAVEATS:
too many to list

• this image only has one partition.
• wait a few seconds after connecting the USB device (check with amidi -l)
• hopefully sysex should be fine (ignored, of course, but should not screw things up). I could not test this (I had to revert to an old version of Midi.cpp because xenomai pipes are not working here).
• no clang on the board
• IDE seems to behave funny when switching project (i.e.: sometimes it keeps compiling the old project or does not save changes in the editor)
• MSW detector and CPU usage detector are broken
• run on boot is disabled (For whatever reason, /etc/init.d/bela fails at boot)
• no supercollider, no libpd, no pyo, no scope no nothing. Only core stuff (if you are lucky)
