You can plug it in as per usual and upload a Sketch in the Arduino software. Click Program then go to the Fuse Bits tab and set it to 0xCF and hit Program again.Īt this point your Arduino is ready. The correct settings for the ATmega168 chip are 0xF8, 0xDF, 0xFF but make sure to use the correct settings for the chip you are using. After you have loaded the correct one hit Program and then when complete move to the next tab. They can be found in your Arduino installation directory, check /hardware/arduino/bootloaders and you will find several variations there, more can be found online. Now move on to the Program tab and under the Flash section select your HEX file. I always hit Read Signature to make sure everything is connected properly. On the next screen select your device, in this case the ATmega168, and select ISP as your Programming Mode. Now select the AVR Dragon as your platform and the USB Port and then click Connect again. We will do neither so hit Cancel and then on the main menu select Tools -> Program AVR -> Connect….
Atmel dragon bootloader software#
AVR Studio 5 is now available, and is the recommended software for this task, but this guide will stand for all who have not yet chosen to update.Īfter loading the program you will be prompted to create a new project or load an old one.

Programming it in AVR Studio 4ĪVR Studio is a free program that only requires you register with AVR in order to download it. Once both boards have power and are connected via the ISP header you are ready to fire up AVR Studio and program the bootloader onto the chip. The AVR Dragon does provide power to the destination board via the VCC headers but I found it’s easier to power the Arduino by hooking it up to another USB cable or via a walwart adapter. The only “gotchya” is when hooking up the ISP cable make sure to align the cable so the wire with the red stripe matches the Pin 1 marker on each end. Unlike setting up the STK500 for HVSP programming the setup for the AVR Dragon in ISP mode is a breeze.
Atmel dragon bootloader how to#
See this Instructables Guide for instructions on how to do that. The AVR Dragon can do High Voltage Programming (HVSP) if you solder on a DIP or ZIF socket on the breadboard area to the right side. In this example I’ll be using the 6 pin ISP header which I will connect to my Arduino board.
Atmel dragon bootloader drivers#
Unfortunately I could not locate stand alone drivers and was forced to download all 600mb of AVR Studio for this purpose only, so I suggest starting that process first so you can get everything else ready while it downloads. Even if you’ll be burning your bootloader through the Arduino program you’ll still need AVR Studio for the drivers. The first thing you’re going to need is AVR Studio. I found this unit hiding in a dusty box on a shelf, seemingly forgotten as no one in knew what it was or why we had it, even though I already had an STK500 hooked up and ready to go as well as a USBTinyISP at home I thought I’d fire it up just for the experience. So if you’re going out to buy a programmer I’d recommend the USBTinyISP, however, if you’re lucky like me and have tons of gadgets like this lying around at work to play with then it’s certainly a viable option. The USBTinyISP is about $10, for comparison, and will get the job done just as easily - actually, it’s easier. They can ring in around $50 per unit, though they do come in a beautiful red box with a dragon painted on it. The AVR Dragon is a little more of an expensive route to go if you’re looking to burn Arduino Bootloaders.
