Connection Error in APM Mission Planner

Earlier today I had the Mission Planner communicating perfectly with the APM (2.5). But now when ever I try to connect the usual window comes up and says "Getting Params… Then that stays for roughly 30seconds then I get "Connect Failed"

by USB can only access the terminal


I'm afraid the board or a part of it is broken. Don't know why that happenend, the problem happened not in the field but at my desk: When I connected the APM via MARVlink it stopped suddenly during reading the values from the copter...


What do you suggest? How can I check if some components or solder broke?

    If you can access via terminal, do a reset and reload firmware. Hopefully you already a saved copy of your parameters, otherwise you'll need to redo your configuration manually.
