I'm new to using atmel studio 7 to work on my arduino boards. I'm doing this because I want to do 'real' embedded systems software development.
I previously had success uploading Blink.c, getting the LED on pin 13 to blink. That was when my Arduino appeared on COM3 (I use atmel studio in virtualbox with Mac OS as host). As of today, my arduino appears on COM4. This is with the arduino plugged into the same (only) USB port on my laptop, so I am a bit mystified as to why it has 'moved'.
I have been unable to successfully upload to my arduino since it changed ports. I am using AVRdude configured as an external tool for atmel studio. The strange thing is that AVRdude reports that it successfully uploads to my board.
Note that I have gone into Tools -> External Tools and updated the arguments to reflect the switch from COM3 to COM4.
My apologies if this thread is a repeat! I did do a couple searches, but came up with no answer.
