LED A off?

Posted by Joe on June 23, 2011 at 5:07pm

For some reason when I move out of CLI mode and hit the reset, the LED A (green) does not blink nor turn solid.  What have I done wrong?  When I am in CLI mode, it is solid.

 

I have tried using the mission planner as well as uploading the code manually.

 

The planner cannot communicate with the APM either for some reason...the count down (timeout) reaches zero, maybe this could indicate something else is wrong as well?  I tried adding #define GCS_PROTOCOL GCS_PROTOCOL_MAVLINK, but still no luck.

 

Thanks

    Whenever you have problems like this, it's possible that a crash has corrupted the EEPROM. Do a CLI reset/clear and then set it up again

    Between last night and today I don't believe I did anything differently, but for some reason it is working now. 

     

    LED A still would not come on unless the motor signals were plugged in after the APM was booted.  Is this the standard?  I could not find this in the manual and I do not remember reading it.  I read 'If you've kept the four-wire connector from APM to the power disconnected for safety, now is the time to connect it.'  Is this referencing the signal wires?

     

    First few flights have been a new success!  It looks like I have a new leaf blower as tree droppings were flying everywhere.

     

    Thanks for the help!

    Keep the Mission Planner terminal open and the USB connected and post what it shows when you reboot with the slider switch in flight mode. There is a lot of diagnostic info coming over that port before MAVLink kicks in.

    Not beeing an expert, by what you describe, seems to me the IMU is not comunicating with APM. That happened to me some days ago after a somehow violent flight. Seems that some of my weldings were not 100% even if they looked like.I would advise you to recheck all the weldings, and if any of them is in short circuit. Even if they look ok, re weld some of them (the ones from the connectors).
