Ardupilot Disco filesystem

Hey, I’m going through this page:
and ran into an issue when editing the /etc/init.d/rcS_mode_default file. The file system on the Disco is read-only.

How do you edit that file?
(note that I’m telnetting in to the disco to attempt to edit the file)

No need to modify /etc/init.d/rcS_mode_default file.

  1. download arduplane from here:

  2. switch your disco on. connect by wifi to DISCO1 wifi network provided by your drone.

  3. open on your computer
    At this moment you should see your drone’s internal file folder structure

  4. copy the downloaded arduplane file into
    and to make the ardupilot executable allowed to run as a program on the DISCO do:
    chmod +x /data/ftp/internal_000/ardupilot/arduplane

  5. press the airsped(On/Off) button on your drone 3 times.
    The drone should start the arduplane and give a distinct sound.
    If the above doesn’t work, do
    chmod +x /data/ftp/internal_000/ardupilot/arduplane
    and look for output or error messages.
    Let me know if you need any clarifications, and…
    good luck!

Do you know how to config the parrot chuck to use a external esc with more amp?

@AndersBringmyr, as far as I know, the Disco has 6 pwm outputs which can be connected to either servo or ESC, but I haven’t tried it. They are covered with the red rubber plugs and only two used for servos. @tridge is the best expert in this area, but I think he is very busy nowadays. Here are useful instructions, and here is more info about the capabilities.
Hope it helps, esp. the first link.

OK I will see if I can get in contact with Tridge…


HI, I want to do the same … did you manage to get it working?
