I have spent last night and this afternoon and evening on this. I have read everything I could find and tried everything that was offered. I just keep getting waiting for Mavlink on both of them?
APM 2.5 (brandnew) and APM 2.5 1 month old.
MP 1.2.45, mav 1.0.
2 x Minimosd 1.1 with V2.0 Firmware and latest charset and tried minimosd extra, and 1 x RCtimer Mavlink osd.
I a not running 3DR although I do have them.
I take it that the pinouts of the Telem Port from inside are Vcc,Tx,Rx etc running Tx - Rx and Rx - Tx etc.
1 APM is for Arducopter and 1 for Ardupilot.
I got the minims yesterday and when I first plugged them in they both worked fine. I wanted to try extra so I uploaded it, changed the parameters in MP as per wiki for minim extra and didnt work for either copter or plane.
Reloaded minim hex and charset on osd, cleared eeprom and factory reset in both APMs and still nothing? I have changed rx-tx pins on the cable and still nothing.tried with 12v to digital side for charset. I have tried reset.
What am I missing. As it worked when I first got it I thought factory reset would do the trick as it just worked when I first got it.
