Sketch Size too big on Mac OS X

Posted by Jeff on November 21, 2013 at 9:19pm

Totally new to Arducopter here and doing some experimentation for the first time, so sorry for what's probably a stupid question!

I'm using the modified version of Arduino on Mac OSX and just pulled the latest source code (ArduCopter V3.1-rc7) from the github. Even with the modified version of Arduino, I'm still getting errors that say my sketch is too big when trying to compile Arducopter for APM 2.x:

Binary sketch size: 262,354 bytes (of a 258,048 byte maximum)

Did I miss something? I basically did the Mac equivalent of everything listed here: http://dev.ardupilot.com/wiki/building-apm2xe-on-windowsdev_for_windows/ Is there anything additional that I need to mindful of on a Mac instead of a Windows box?

Trying to build APMRover2 and ArduPlane didn't result in the same error…. just Arducopter.

Thanks for the help!

Install MHV_AVR_Tools, my Arduino solved.

  I have gcc version 4.8.2 and I am getting the same error of the sketch being too large...

    actually any 2 ways to solve it:
    
    1. Have you install MHV_AVR_Tools ?
    
    this is link of MHV AVR Tools : https://infernoembedded.com/products/avr-tools/release/20131017
    
    2. Find file APM_Config.h and Uncomment to reduce memory used.
    
    look this part: "// uncomment the lines below to save on flash space if compiling for the APM using Arduino IDE. Top items save the most flash space"
    
    I hope it can help you.

Found the solution for this, Go to the APM_Config file and disable some stuff you dont use, under

// uncomment the lines below to save on flash space if compiling for the APM using Arduino IDE. Top items save the most flash space

Pick stuff like optical flow and auto tune

Just as a followup to this, make sure your board type is set to the Mega 2560 in the tools menu. Although usually if you have the wrong board type selected you'll have compile errors in the code before it complains about the sketch being too big.

Hello everyone,
Now I have successfully downloaded "adruino IDE 1.5.5 beta" on my Ubuntu Linux and it is working perfectly fine. There is no problem with binary sketch size. New sketch I am getting is in the range of 360K which is well below 258K space available in APM2.5 board.

This might work fine on Windows and Mac too.

Cheers!
