I also recommend you get the ATMega328 data sheet.

Inspect memory, single-step through code, set break-points (at which execution will stop), inspect registers and input/output port values etc.
#Atmel dragon how to#
The previous post describes how to get started with using the Atmel Studio simulator, which is a good introduction to the activities required during on-chip debugging (OCD) without needing to fiddle quite so much and without wondering whether the hardware is playing nicely. This really notes for myself for next time, when I’m bound to have forgotten the recipe, but I hope someone else will find it useful. There are quite a few brief comments on the forums and people asking how to do it but nothing really good, with the possible exception of a post by Steve Cogswell which refers to an old version of Arduino and an old version of Atmel Studio. The following related articles show how to connect a programmer (AVR Dragon and AVR ISP mkII) to an Arduino board and restore the bootloader using Atmel Studio 7 on an Arduino Uno and Arduino MEGA 2560.This post is motivated by the lack of information about using debugWire with an Arduino (or similar) on the web. load the Blink sketch to flash the on-board LED Related Articles Start the Arduino IDE and load a sketch to test that the bootloader is working, e.g. Click the Program button Arduino Uno Fuse Setting - click for a bigger imageġ4. After programming has finished, click Fuses in the left paneġ2. Click the Program button Burning the Arduino Uno Bootloader - click for a bigger imageġ0. Browse to the bootloader hex file using the. Click Memories in the left pane of the dialog boxĨ. You can click the Read button under Device signature to make sure that you can connect to the ATMEGA328P microcontrollerħ. In the Device Programming dialog box, select AVRISP mkII in the Tool drop-down box, ATmega328P in the Device drop-down box and ISP in the Interface drop-down box Atmel Studio Interface Settings - click for a bigger imageĦ. In Atmel Studio, click Tools → Device ProgrammingĤ. Connect the hardware as described aboveģ. The bootloader in this folder that must be loaded to the Arduino Uno is optiboot_atmega328.hex Steps to Burn the Bootloaderġ. In version 1.0.1 of the Arduino software, you will find the bootloader in the Arduino folder:Īrduino-1.0.1\hardware\arduino\bootloaders\optiboot\ The bootloader is included with the Arduino IDE software.

Power up the Arduino either from the PC via a USB cable or by an external power supply. Pin 1 is marked on the AVRISP connector and on the Arduino header. Make sure that you connect it the right way around. Plug the AVRISP ribbon cable connector into the 3 by 2 header on the Arduino board. Plug the AVRISP mkII USB connection into a spare USB port on the PC.

The best solution to this problem is to use Atmel Studio to burn the bootloader, rather than removing Atmel Studio and its drivers. The Arduino IDE displays the error message:Īvrdude: usbdev_open(): did not find any USB device "usb"
#Atmel dragon driver#
If you have loaded Atmel Studio on your PC and you try to burn the bootloader to the Arduino using the Arduino IDE, you will get an error message in the Arduino IDE because of a driver clash between Atmel Studio and the Arduino IDE drivers.
