I own a ARDUINO DIECIMILA but as i am a beginner i want the simple and best method to put my .hex file to arduino board ,without buying and hard ware or soldering the board plz help :slight_smile:

If you need to change fuses or locks you will need to get an ISP device.

If you just have a .hex file you want to load onto the Diecimila you can use the avrdude utility that comes with Arduino to upload the file through the bootloader:


Do you know anyone with an working Arduino board? You can program it to function as an ISP and use it to load a bootloader in your device.
