Fatal Unhandled Exception: SOLVED

[andrew_sinclair]

Hello Steve,

I am in the process of moving over from my PC based v1.9.4 (build 1099) to the latest Cumulus MX v3.0.0. (build 3038). using a Raspberry Pi 2. I am keen to explore/test the Twitter and WoW uploads.

I read the "...installing Cumulus MX.." thread and opted to run Cumulus MX with my existing data, thus I took a copy of my existing Cumulus directory and then unzipped Cumulus MX into it. When I tried to run Cumulus MX using the

sudo mono CumulusMX.exe command the terminal window looked like this:

root@raspberrypi:/CumulusMX# mono CumulusMX.exe
Current culture: English (United Kingdom)
Serial: 74FECEABEB2DA94ECB5EBA0CD11A7137

and the file in the MXDiags folder looks like this:

It may be that some of the details in the Cumulus.ini file are unsuitable for the Pi (the serial port will be different, for one thing). So while starting from a Cumulus 1 installation works in most cases, perhaps some detail is causing a a fatal exception in your case. Have you tried a 'fresh' installation?

Have you tried a 'fresh' installation?

I just tried that and it has started ok now and I am just setting the settings now.

the serial port will be different, for one thing?

What should the serial port setting be or is that something I should be able to find from information relating to the raspberry Pi?

[andrew_sinclair]

I changed the Serial Port to that I was using in the Cumulus v1.9.4 (build 1099) installation COM4 and CumulusMX terminated with...

System.IO.IOException: Bad file descriptor

**** An error has occurred - please zip up the MXdiags folder and post it in the forum ****

File attached...

[steve]

But COM4 isn't a valid com port name on a Linux system - see the MX FAQ.

Cancel my posts above, sorted now...I should have read the FAQs more carefully
