I'm having the exact same problem.  I wrote and updated code for a day, then moved the arduino to another computer, and I get the same errors.  The original code still executes, I just can't upload new code to the board.  Is there a way to reinstall the firmware?

I fixed the problem I was having by getting the newest build of the Arduino software and reinstalling the driver from the Arduino folder.


I have the same issue with the Mega2560R3 board.

I have WinXP SP3 on a ThinkPad T-40.  I have tried on a different machine with the same errors.

I tried the 'press the reset button' just after hitting the upload.  Four tries and Blink finally uploaded.

Blink is running, but I wanted t play and changed the timing pause statements, but have not been able to upload.

I have tried the other ISP with no result.

My Com port shows Arduino Mega 2560 R3 (COM6) and the driver is usbser.sys Microsoft Corp 5.1.2600.5512(xpsp.080413-2108)


I have selected the correct board and compost, and have used the AVRISP mkII

The RX light blinks once in a while.

Thoughts to help me get this running?
