I follow the tutorial http://ardupilot.org/dev/docs/learning-ardupilot-the-example-sketches.html#learning-ardupilot-the-example-sketches
The examples/INS_generic can be build and upload, but the serial port does not show any data. I am facing with the below line on the terminal when i am connecting to Pixhawk,
Telemetry log: mav.tlog
I have stuck on this for almost ten days.
Thanks for your help!
