Upload Failures

I was merrily compiling along when, out of the blue my code stopped uploading. I changed USP ports several times, I tested with a different board. I tried a completely different program. I rebooted my computer. Same failure persists. If it isn't the board or my code, what could it be and how do I fix it?

The build output is attached.

This is the command to upload. Your can try it from a .bat file or cmd prompt

Code
Select All
D:\Arduino\hardware\tools\avr\bin\avrdude "-CD:\Arduino\hardware\tools\avr/etc/avrdude.conf" -v -patmega2560 -cwiring "-PCOM28" -b115200 -D anoBot.ino.hex:i"



Check windows device manager to see which usb driver is installed.

Thanks, but when I run that command, here's what I get:

I checked Device Manager output and it lists Arduino Mega (COM28) and says "This device is working properly"

You are outside of Visual Micro when you run the command so can find help in more technical places for your toolchain.

The access denied error you are getting normally suggests the port is open in a serial monitor.

You should also check windows task manager to ensure the avrdude.exe process is not locked and hogging the port. It you see an avrdude process you should terminate it.
