Topic: Unable to upload sketch (Read 1 time) previous topic - next topic



I am new to arduino, i am trying to upload a sketch and getting following error.

open nul: the system cannot find the file specified.
error compiling for board arduino/genuino uno.

OS: Windows 10
Arduino Ide : 1.8.5

Please help


I think you may want to read this post first and add some extra information.

Also make sure you are not using a USB 3.0 port and that you have selected the correct COM port as listed in windows device manager for the board (you failed to mention type).

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google (who would have thunk it ! ) or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

I have some problem while uploading arduinoisp to new atmega328P-PU it shows invalid library and bootloader while click this message shows...

avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

Error while burning bootloader.



If you want, try out this post, Error conpiling to Arduino Uno-SOLVED!


Hi... I am also new to Arduino and I can't seem to upload a sketch. Any help would be greatly appreciated.

Arduino: 1.6.11 (Windows 8.1), Board: "IntelĀ® Edison"

Sketch uses 76,331 bytes (0%) of program storage space. Maximum is 10,000,000 bytes.

Are you certain your Edison board is on COM5?

Try this:
  • With the Arduino board unplugged from the USB open the Tools > Port menu and note the listed ports. If the Port menu is gray and disabled then that means there are no ports available.
  • Close the Tools > Port menu.
  • Plug in the USB cable on the Arduino board
  • Wait a little while for the Arduino board to connect
  • Open Tools > Port, the new port on the list is your Arduino board. In some cases it will have the name of the board next to the port name but this doesn't happen with all boards. If the Port menu is gray and disabled then that means your Arduino board didn't install correctly. You may need to install a driver.
  • Select your Arduino's port from the menu.

If the COM5 port is correct, try restarting your computer. Sometimes COM ports can get stuck and cause this sort of problem.
