Mac + Uno + avrdude: stk500_recv(): programmer is not responding

I'm trying to upload .hex file to Arduino. I don't have any problems with uploading code through an IDE (like blink example or any other). The port and board are correct.

So, the problem appears when I try to upload

avrdude -pm328p -carduino -P/dev/tty.usbmodemfd121 -b57600 -D -Uflash:w:grbl_v0_8c_atmega328p_16mhz_9600.hex -v -v -v -v

What I tried:

  • I have 4 Uno's at the table (original + free versions), the same issue.
  • I have installed newest drivers from here, tried with and without them.
  • tried with avrdude which comes with Arduino IDE (1.0.5 and nightly builds) and newest avrdude v.6.1 brew install avrdude
  • different baud rates down to 9600
  • tried to press reset after bytes are sent like suggested here

What fixed it for me was:

  • Disconnect the USB cable from the Arduino
  • Try to upload your program
  • This will fail and the Arduino app will ask you which USB port to use.
  • I did this twice
  • Then plug in the USB cable to the Arduino
  • Upload you program... succes!

Note: Shortly before I installed the drivers mentioned by Mikhail.

Setup: Mac OS 10.9.5, Arduino.app 1.0.6, Arduino Duemilanove
