  • Hey Guys, The fuse settings you have used in your board file are wrong. The resonator is not being used. You have it set to use the internal oscillator. The internal oscillator has ±10% accuracy before calibration. The resonator is ±0.01%. You have them set at:

    //Sparkfun Defaults
    mega2560v.bootloader.low_fuses=0xE2
    mega2560v.bootloader.high_fuses=0xD8
    mega2560v.bootloader.extended_fuses=0xFD
    

    They should be

    // Updated
    mega2560v.bootloader.low_fuses=0xF7
    mega2560v.bootloader.high_fuses=0xD8
    mega2560v.bootloader.extended_fuses=0xFD
    
  • Are the source files for firmware available?

No public wish lists :(
