Please add some details, like when crashes: "when i go to firmware tab... " for example.

You can add a log while starting the app with "-log log.txt" at end. This output console content to log.txt file.

Also start GCS using the "clean configuration" link from program menu

I dont get that far. After the logo pops up it crashes after a bit. Here is what the windows log says:

Faulting application name: librepilot-gcs.exe, version: 0.0.0.0, time stamp: 0x572d95fa
Faulting module name: Qt5Gui.dll, version: 5.6.0.0, time stamp: 0x5707b180
Exception code: 0xc0000005


If I run the clean GCS shortcut it launches but the GCS comes up with a totally black/blank screen. Now the regular exe doesn't crash anymore but gives the same blank screen.

Ah, so there is something....

Try reinstalling with MesaOpenGL ?

Yes, that did the trick. Now it launches just fine and I can see the contents of GCS. Flight data screen and PFD look normal too. Thanks.

Thank you both!

Read through all this but can't find the info on how to set up the Flexi port etc for the Next build to get external mag working.  Saw it somewhere couple weeks ago but need all the GCS setup. Tried some settings last night but GCS says no external mag found.

Ublox m8n with magnetometer. Single 4wire connector plugged in Flexi port

Maybe I misunderstood, but I thought the latest build (next) allowed us to use only the 4 wire connector on the m8n GPS with magnetometer?  In fact I found the directions I was looking for (I printed them and there is no name or header info so I don't know where or who did them). These directions imply that only the Flexi port is required. No mention of adding the 2 wires on setting up any other port? There is no connection info in the write up!!

[f5soh]

I2c mag is connected to the flexiPort set as I2c.
If you follow wizard, the connection diagram show all you need at some point.

Found it! Here is the link. Reading it again I can use 1 cable to get both GPS and mag!

Only if you have a GPS Platinum (aka V9) or a DJI Naza GPS or it's clone.   All others require two ports.

Using build 15.09+r616-g4ada670. Followed setup instructions in link in above post.  When I set the Flexi port to i2c GCS reports no GPS in system page and Aux mag not found in the attitude<magnetometer tab. If I set Flexiport to GPS the GPS works but of course no AuxMag detected.

Now I may be causing myself problems, I am testing this on a spare Revo board with no receiver or ESCs connected. Didn't want to test on a quad first.   Could this be causing the problem? Doesn't seem related BUT?  Using 5v BEC and M8N Ublox GPS with magnetometer .

I just saw a comment that this GPS + Mag may not be one that works with Next? Only 1 four pin connector but listing on Amazon says for Revo.  (Probably just means the connector fits and GPS works - gotya)
