I have a new Arduino Mega 2560, and I can't upload programs to it anymore. :(
I have been able to upload to it before.
I have checked the COM port, Board, and I am running Windows 7 with IDE 22.
When I try to upload, this is what i get:

avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: ser_send(): write error: sorry no info avail

Also, loop back test doesn't do anything, RX TX leds aren't lighting up, and the Computer is able to detect that an Arduino Mega is connected.


  I have a similar problem with my Mega. It still runs the last sketch that I put in it but, I can not upload a new one. The IDE just sets there saying uploading but, never seems to do anything. Using 022

I had hideous problems uploading scripts to my Mega from a Vista box.  They all went away when I plugged the USB direct in to the PC, rather than via a USB hub.  Worth a try.   :)


I tried conecting my arduino duemilinove with out the ic, connected the rx tx gnd 5v and the reset pins.. i still wasn't able to upload anything...
