Hello,
When trying to upload to a Due, I get:
Uploading 'Blink' to 'Arduino Duemilanove or Diecimila w/ ATmega168' using 'COM6'
The uploader returned an error
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x45
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 2 of 10: not in sync: resp=0x45
avrdude: stk500_recv(): programmer is not responding
.
.
.
Are there any requirements before attempting to upload to a Due?  The Nano needs a 10 mF capacitor from Pin3 to GND to prevent repeated resets.
Anything like that for the Due?
Do there exist any written instructions for uploading and debugging?
Thanks.

Thanks much for your reply.
There is NO "Arduino Due" of any kind on my board list.  Neither in the Arduino IDE board list. Only the "Arduino Duemilanove or Diecimila".  I tried both Mega368 and Mega168. Neither of those work.

Do I need to install something else?

First let me ask, is the DUE board the same as the:
Arduino Duemilanove or Diecimila?

Secondly, do i have to put a 10micro farad capacitor from the reset pin to ground before trying to upload?


I have tried using the Arduino IDE with this board, and get:

I installed the Arduino Due (Programming Port) to show up in both VS and the Arduino IDE.   
I now get (using VS or the Arduino IDE):

Uploading 'blink' to 'Arduino Due (Programming Port)' using 'COM6'
Upload failed
bossac.exe: extra arguments found
Try 'bossac.exe -h' or 'bossac.exe --help' for more information

Any thoughts?

No. Using the Arduino IDE, I get the error:

ino/bossac.exe -i -d --port=COM6 -U false -e -w false -b nk.ino.ino.bin -R 
bossac.exe: extra arguments found
Try 'bossac.exe -h' or 'bossac.exe --help' for more information.

I will search for what the problem might be...

If you have configured vm to look in the same arduino folder then it should be automatic if you have restarted the ide since upgrading arduino.

However the issue you hit is because arduino added a new property to the core recently. When you have upgraded to the latest core you hit a problem with the arduino ide and needed a newer version. The same will always apply to Visual Micro so please ensure you are using the latest version.

Hi,

Don't get confused with Arduino Ide version and Toolchain versions. They are almost the same but different. It's how Arduino designed it You will see the same version numbers in the Arduino Ide boards manager.

"Tools>Extensions and updates" should show you updates. A flag should also appear in the title bar of visual studio when new updates are available. + You can always find information on visualmicro.com which also has a downloads page. 

Hi,

If you are using 1605.28 that is the latest. For you information in "tools>Extensions and updates" you have to click "Online" or "Updates" to see newer versions. However no need.

Visual micro works fine with the 1.6.8 sam core. I tried it earlier today but there isn't much difference between all the versions.

Good to hear it's uploading for you now.

When you get time please switch on vMicro>Verbose then try the upload and email or post the output that appears.

That will explain what the issue is.

Thanks

Great.

Bear in mind that normal debug for arduino is adding your own serial print messages to the code. The visual micro debugger can do a lot but it's not quite the same as a full blown debugger.

The docs are on visualmicro.com let me know if anything isn't clear.
