Upload retry count?

I recently both upgraded and purchased a commercial license for Visual Micro and this (small) issue of mine has appeared since then.

When I hit compile and upload, without a board plugged in to a COM port, it seems to try the upload 7? times before failing. The output from this is just:

Code
Select All
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_ReceiveMessage(): timeout
avrdude: stk500v2_getsync(): timeout communicating with programmer


Is there a setting somewhere to change this back to a single attempt? Or is this not a feature?

I actually often upload to a custom Atmel board that is plugged into the Serial port of a linux server in another workshop. I upload to this device using a plugin I wrote for visual studio which waits for the normal compilation to finish before finding and pushing the new .hex file to the server. With only one attempt to upload, this worked flawlessly and also lets me upload to local boards with the same button but now Visual Studio actually stops responding for a few minutes whilst it does these 7 or so retries.

Thanks in advance.

Hi,

Thanks for the post and buying Visual Micro.

If you have Visual Micro set to upload via COM port then it will not attempt to run avrdude if the COM port is unavailable. Instead you will see the following message and no attempt to upload will be made:-

Code
Select All
Uploading via Bootloader
Flushing the serial port
The port 'COM3' does not exist.


It would be helpful to see the verbose upload commands (see tools>visual micro>verbose) but it looks like avrdude it attempting a programmer upload. Is this your code causing avrdude to run or maybe you have inadvertently clicked tools>upload using programmer?

Any retries shown are a result of avrdude which is part of the Arduino IDE tool chain? When you upgraded Visual Micro if you also upgraded your Arduino Ide then this would account for any change in avrdude performance.

You might also like to know that you can create custom programmers with arduino 1.5.x and Visual Micro. This would allow you to push your hex files using your own exe code or batch files allowing Visual Micro to upload without need for an addin and also preventing any other form of upload attempt other than your own commands.

Hopefully some of this points you to a solution if not the please post the verbose upload command

Thanks
