Topic: Arduino UNO R3 and OS X 10.8.4 - Uploading Problem (Read 1 time) previous topic - next topic


I'm having this problem too, with the following notes.

  • have been able to upload from the Mac (OS X 10.8.4) previously, including earlier today

  • am able to upload from a Windows 7 machine

Currently, if connected to the Windows 7 machine everything looks normal, program runs, etc. I've gone back to just the blink sketch for now. When connected to the Mac, that sketch no longer runs correctly and LED L has a strange blink pattern, on a little long, off, then a set of very fast blinks. 

I've been able to switch back and forth between the Windows and Mac machines previously. I updated to Arduino 1.0.5 on the Windows machine just prior to encountering this issue.  Mac has version 1.0.5 also.

Coding Badly


The same USB cable was used in both cases, but tried a different one anyway.  No difference.

Eventually got it to upload from the Mac again, after getting a few other types of errors first (getsync, getparam protocol error). Not sure what change made the difference.
