mission planner displaying "bad gyro" and "disarmed" when 2.77 arduplane code is burned

Posted by darshana unnikrishnan on February 18, 2015 at 3:24am

I am a newbie in this field and would like to get some help related to the PILS setup.

I have been burning 2.68 code into APM 2.6 board and performing PILS and no error was got. But the same was done for 2.77 code and I am getting "disarmed" & " Bad Gyro Health" displays in Mission Planner.

As 2.77 code uses L1 guidance and there are some extra tuning parameters, I have changed the Mission Planner to the Latest one. I had tried many other versions of the Planner too. But all the time the same errors are being displayed.

Also I found that Arduino IDE 1.0.3 is needed to burn the 2.77 code to the APM 2.6 board. Otherwise I have not done any changes anywhere.

Please Tell me whether it is the problem of not using the correct Mission Planner or some other reason is there. Or maybe the problem is with code. I am new to this field so any help will be appreciated.

I'm just curious but is there a reason your not using the latest stable release of Plane? As of yesterday the latest version is now v3.3.0.

Thanks, Grant.

I had this problem happening, however I got worried because it completly disarmed the copter when it was armed and flying...

How can this happen ?

How to avoid this ?

just one more question which mission planner is best suited for 2.77 code of arduplane

@roadracer thanks a lot. will try out and then let you know

@hein du plessis thanks but i dont think thats the issue as the board is working fine with 2.68 code.

thanks Roadracer but how to write Clear EEPROM sketch alone also now the board is not getting connected to the mission planner itself when i burn 2.77 code. but it is all working well with 2.68 code. any thoughts on it??

  You should write it with Arduino IDE. When uploading is done, wait for about 1s, there will be led light turned on (clearing EEPROM complete). Why don't you take MegapirateNG 3.0.1 R4 from github https://github.com/MegaPirateNG/ardupilot-mpng which is newest.
  
  Here is manual to follow. I did this with Arduino IDE. I had same preblem that board did not want to connect in Mission planner.
  
  http://docs.megapirateng.com/documentation/compile
  
  If you configure it right it will connect. Do not use precompiled versions of hex in mission planner.
  
  Follow config manual:
  
  http://www.megapirateng.com/how-to-configure-mpng-3-0-1-firmware/
  
  Basic settings must be done in Arduino IDE. After that you will make all configurations in Mission Planner.
  
  Hope it helps.

Check for blown 3.3v regulator?

Did you calibrated compass and gyro? You should also first write Clear EEPROM sketch (arduino examples) and then write arduplane. Had similiar problems.
