ATmega32U4 Mod

Postby MuazSalah » Mon Feb 27, 2012 9:22 am

Hi,


After I started playing with the ATmega32U4 Breakout Board, I realized that the bootloader will not work except on the beginning of the code, which mean that I need to hard-reset the board for each programming.


My planned project requires that I am able to reprogram without touching the board, so I thought if it would be possible to modify the code and add it to my code such that the board will achieve normal functionality plus being able to reprogram it without resetting the board.


Is this possible? Any hints?

Thanks!

The LUFA documentation describes how to drop to the bootloader via software. I have not tried this so I don't know if it works with the Bootloader on the breakout board.
