Maestro losing network when debug is on



  • I have noticed this strange behaviour that when there are lots of output on the debug serial port the web server on the maestro stops listening. It still responds on ping.

    borg@debian:~$ ping 192.168.0.36
    PING 192.168.0.36 (192.168.0.36) 56(84) bytes of data.

    Normally there are little to no output on the serial port and the problem does not occur. But enabling debugging printouts or if there are many warnings from the firmware it occurs.

    I'm still on the dev branch from mid January, perhaps I should git pull.
