Hi, I have used MPIDE (0150) to successfully verify and upload sketches to a chipKit Uno32. However, when I try to do the same with an Arduino Uno, the program seems to hang and never completes. The computer doesn't lock up or anything, it just stops processing. I'm using Win XP. I have made sure that I've selected the board and port correctly.

The messages I get are:

java.lang.NullPointerException at at at at at at$ at

Any help regarding what I'm missing will be appreciated. Thanks!

MPIDE doesn't work with the Arduino boards any more. It's old stuff from before the dawn of time.

If you want an IDE that does them all, then either UECIDE (link below) or use the Arduino IDE and install the chipKIT Core package (experimental) from github:

Thanks, majenko! Worked like a charm!
