I’ve just updated my MangOH Red as outlined [here](https://mangoh.discourse.group/t/updating-legato-green-and-red/1508). 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 192.168.2.2

Step 3) produces the output:  
Applying update from file ‘timerLed.wp85.update’ to device at address ‘192.168.2.2’.  
Unpacking package: 100% ++++++++++++++++++++++++++++++++++++++++++++++++++  
Applying update: 100% ++++++++++++++++++++++++++++++++++++++++++++++++++  
SUCCESS  
Done

Unfortunately, once the update is complete I get an output on the SSH terminal:  
root@swi-mdm9x15:~# app status  
packet\_write\_wait: Connection to 192.168.2.2 port 22: Broken pipe  
mangoh@mangoh-virtualbox:~$

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.
