To get the bootloader onto the ATmega you need to connect an flashing tool (like USBasp) to the 6-pin ISP connector on the board.

Simply flash the .hex file to get the bootloader on the chip, and change the high fuse at the same time.

There are many different options to upload a .hex firmware file to the MULTI-Module and to set the correct fuses. This document outlines an approach that uses a USBASP programmer and which is equally compatible with OSX, Windows and Linux operating systems.

1. Make sure to write down the location of your installation since you need to know where avrdude is installed to configure the AVR8 Burn-O-Mat. For example on a default windows installation, avrdude.exe is located in "C:\Program Files (x86)\Arduino\hardware\tools\avr\bin" where "C:\Program Files (x86)\Arduino" is the installation path.

- off: program not running or a protocol selected with the associated module not installed.
|

- flash(on=0.1s,off=1s): invalid protocol selected (excluded from compilation or invalid protocol number)
|
||||
- slow blink(on=0.5s,off=0.5s): serial has been selected but no valid signal has been seen on the RX pin.

- fast blink(on=0.1s,off=0.1s): bind in progress.

###Bind

### Bind
|
||||
Make sure to follow this procedure: press the bind button, apply power and then release it after 1sec. The LED should be blinking fast indicating a bind status and then fixed on when the bind period is over. It's normal that the LED turns off when you press the bind button, this behavior is not controlled by the Atmega328.

||||
For serial, the preffered method is to bind via the GUI protocol page.
