When I go to upload a sketch to my Arduino Duemilanova ATMEGA328 I get the following error:
avrdude: stk500_getsync(): not in sync: resp=0x00
I performed the "Loop Back Test" and all seems fine. Anything I type in the serial monitor is echo'd back to me.
One strange thing, under normal use the Serial Monitor is filling up with random data. I assume this is causing my problem:
It churns out this data at a rapid rate. If I leave the serial monitor open, it will eventually crash my machine.
Hope someone can help, looking forward to getting some real work done.
