MangOH unit resetting after application update


I’ve just updated my MangOH Red as outlined here. I’m now attempting to run ANY application on it with some interesting results.

I attempted to use TimerLed with only to have the connection dropout. The steps I’m taking are:

  1. cd mangOH/samples/tutorials/mangOH_Red/gpio/TimerLed
  2. mkapp -t wp85 timerLed.adef
    3)$ app install timerLed.wp85.update

Step 3) produces the output:
Applying update from file ‘timerLed.wp85.update’ to device at address ‘’.
Unpacking package: 100% ++++++++++++++++++++++++++++++++++++++++++++++++++
Applying update: 100% ++++++++++++++++++++++++++++++++++++++++++++++++++

Unfortunately, once the update is complete I get an output on the SSH terminal:
root@swi-mdm9x15:~# app status
packet_write_wait: Connection to port 22: Broken pipe

it then takes a while for the board to reset itself so that you can once again SSH into it. Once done I see that the application that should have been updated/installed is not there.

any help getting this back to where its usable would be very much appreciated.


I have mentioned in another post, this could be power related and when using a supplementary battery the issue (at least as noted there “SSH connection drops out”) does not occur and can’t be duplicated.
