Mac + Uno + avrdude: stk500_recv(): programmer is

Question

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

Answer 1

I had same problem with Ardunio Leonardo board. I notice that I forgot to set my board version from IDE. After selecting correct board (Tools --> Board --> Ardunio Leonardo) problem solved.

Answer 2

Successfully solved with Hex Uploader.

It is created for flashing .hex files to Arduino for Mac OS.

Options for other OS are described in the grbl documentation.

Answer 3

Had the same problem. But my fixed it by going to Tools->Serial Port, then selecting tty.ADR6300-SerialPort

Answer 4

I had the same error, and the problem was that I used pins TX/RX in my schema (you need them to be free when uploading).

Answer 5

I just bought an arduinomonkey nano board from Amazon and ran into this exact problem. I am running Arduino software version 1.0.5 and mac osx version 10.9.4.

I tried many different suggestions (like holding reset as you upload) and none of the worked reliably. In all the documents it states that for Mac no updated USB drivers are needed however, I just downloaded the updated drivers from: http://www.ftdichip.com/Drivers/VCP.htm (2.2.18)

after downloading and launching the FTDI..._10_4_.... file. After it installed, went back to the arduino IDE and uploaded a sketch...it worked perfectly!

Answer 6

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
