avrdude: stk500_getsync(): not in sync: resp=0x00

Hey all
I have been trying to load code onto a Arduino MEGA 2560 using the command line rather than the ino. I keep getting the error message "avrdude: stk500_getsync(): not in sync: resp=0x00". I have seen this error message on the forums quite frequently and nothing I seem to try works. I attached a picture of the error also.

  • I have tried unplugging and plugging the USB.
  • I have tried a new board
  • I have made sure that I have the right syntax for selecting the board
  • I have checked the COM port on the devices manager (even after changing boards)
  • I have tried hitting the reset button at the correct time
  • I have tired loading different exampls
  • I have tried different baud rates

If I try to lead the examples through the Arduino IDE then everything works perfectly. Not sure really what else to try. I just wanted to be able to program the Arduino from the command line using the binary file. Also, does the compiler produce a binary file that can be located? or is there a temp folder that the binary file is loaded into once compiled?

Thanks!

You could try to posting the text in the window, rather than a picture of it.

Also, does the compiler produce a binary file that can be located?

Of course it does, and it is the full path to that hex file the you should be specifying.

Use File + Preferences and enable verbose mode for compiling and linking to find where the hex file is created.
