I sent a program to my Duemilanove that logged data to an sd card from a displacement transducer. I worked like a charm . I removed the usb cable from the arduino to stop the program. Removed the SD card which had data on it. Plugged it back in and the program wont not start back up. I tried hitting the rest button didn't work. Tried sending a program and kept getting avrdude: stk500_recv() : programmer is not responding. The arduino is getting power and yes the lites blink when I press the reset. it seems like the arduino is blocking me from programing it.
No, AVRDUDE is not running nor is the port locked up. I was able to send a program in win7. But when I send a program in linux I can only send it once and after that I can't connect to Arduino.
