You can check this by looking in the serial port menu of the Arduino software. Your board should be ready and up to date. If your board has an atmega8u2 type atmega8u2 instead of atmega16u2 in the command lines above. Sudo dfu-programmer atmega16u2 flash Arduino-usbserial-uno.hex When this command is done and you get a command prompt again, type If you saved the firmware in your downloads folder on OSX, then you might type Mac & Linux: from a terminal window, change directories to get into the folder with the firmware. Windows: use flip to upload the hex file to your board The serial port for your board should no longer show up.
To verify you have reset the 8u2 or 16u2 chip: In the Arduino programming environment, check the list of serial ports. You'll need to solder a 10k resistor (Brown-Black-Orange) at the back of your board in the same location as this picture.
On OSX, right-click or command-click on the Arduino application and select "show package contents" to find this folder. The firmware is also located with the Arduino software in the /hardware/arduino/firmwares/arduino-usbserial folder. sudo allows you to run commands as the administrator of the computerĬhoose the version that is suitable for your board, either arduino-usbserial/Arduino-usbserial-uno.hex or arduino-usbserial/Arduino-usbserial-mega.hex Use the password you login to your Mac with. NB: If you've never used sudo before, it will ask for your password. Once MacPorts is installed, in a Terminal window, type
#Atmel usb driver arduino install#
Mac: Install MacPorts following these instructions: Windows: Download Atmel's flip programmer from here This is the software that will update the code : The firmware version is listed as "version" (e.g. by selecting "About This Mac" from the Apple menu and clicking the "More Info." button) go to the USB sheet and click on the item for the Arduino board.

Mac OS X: run the System Profiler application (e.g.In one of the properties, you should the VID, PID, and the revision number. Windows (before 7): locate the board in the Device Manager (it should be under Ports), right click on it and select "Properties" in the resulting dialog, click on "driver details" in the "Driver" tab ("Details" in Windows 7).To check which version of the firmware is on your board, connect it to your computer and follow the directions for your operating system: The Arduino Uno and Mega 2560 have been shipping with the updated version of the ATmega16u2 firmware.

Here's how to update the firmware on your 16u2 in a few steps.Ĭheck whether you need to update the firmware It runs software called firmware (so named because you couldn't change it once it had been programmed in the chip) that can be updated through a special USB protocol called DFU (Device Firmware Update).
Previous versions of the Uno and Mega2560 had an Atmega8U2. The ATmega16U2 chip on your Arduino board acts as a bridge between the computer's USB port and the main processor's serial port. Updating the Atmega8U2 and 16U2 on an Uno or Mega2560 using DFU
