Upload Problem(Rx Blinks Only) No Device Found

Hello Everyone,

I’m having a big problem trying to upload new code. The Due is connected to the programming port(COM6) on my windows 7 machine. When I try to upload, the RX blinks a few times and TX does not blink at all. Then “No Device Found” error is given like in the picture below. Even though it is found in Device Manager.

Please HELP,

Try using the native usb port. If it doesn’t even recognize, try pressing the reset and erease at the same time. Then the bossac port will connect. Upload the software using it. Then press reset, and it should work again.

Success! Thanks a bunch for the help Gericom.


Hi! I got the same problem. I tried to fix it like that but it didn't work. Have you got some other ideas.
