Recently I was needed to make some project on Arduino. Unfortunately, given Arduino didn’t flash via UART using Bootloader properely (I don’t really know what happened with it), so I decided to flash it with ISP programmer.
I had AVR Dragon with me and didn’t want to buy another one (supported by Arduino IDE) because I don’t work with Atmel / Microchip MCUs. Thus, I started to search for the information about using AVR Dragon on Linux.
It was a little bit tricky to find anything useful about that, so I tried to merge all the given information and my own experience in this post.
Firstly, I used Arduino IDE to compile my code and export .hex file:
Exported file is located in the project / sketch folder.
Secondly, I connected my Arduino to AVR Dragon using ISP interface by the user guide recommendations. Of course, I also connected power supply to Arduino (I don’t recommend you to use AVR Dragon power pins because of high current value may be needed for your device).
Thirdly, I finally started flashing my device using this command in terminal:
avrdude -c dragon_isp -p atmega328p -U flash:w:your_file_name.hexWhere your_file_name should be replaced with the name of .hex file.
Wait until the end of writing and checking of the firmware. Then, the work is done!!!
As you can see, avrdude natively supports AVR Dragon, so you don’t need to have Atmel Studio installed to use it.
I also found some information about debugging Arduino with AVR Dragon using Avarice and AVR GDB, but I wasn’t needed to debug. Maybe I will try it when I use Arduino or Atmel / Microchip MCUs next time in any project (hope, it will never happen 🙂 ).
