Max upload to DUE?

I have a DUE, whitch until now worked well, but now I can't upload the SW to the board. When trying to upload, it say:

Send auto-baud No device found on COM10 Set binary mode An error occurred while uploading the sketch

But when I use Board Info, it say: BN: Arduino Due (Programming Port) VID: 2341 PID: 003D SN: 5533031373535180C011

I have two other DUE, one is OK, but the last also fault, it is on COM6.

Is there a max uploads?

There is no maximum number of uploads, except that you can only write the Flash maybe 10000 times (or more).

Have you tried to push the erase button for 3 seconds, then the reset button for 3 seconds then choose the correct COM port ( COM X (DUE Programming Port)) if you are using the programming Port., then upload your sketch.

Do not plug any external peripheral to your board when uploading.

Yes, I have tryed to erase and reset a lot og times.

The errors started some time ago, and then I user erase to get it to work, but it do not work any more. I have uploadet maybe 500 times but not 10.000.

I don't use all the program memory. Is it possible to tell the uploader to use another area to store the program?
