Old ATMega 328
4 December, 2012 - 16:29
I have an old ATMega 328 with v2.4 firmware on it I think. I'd like to use it to make a breadboard arduino but I can't get it to accept any programming, presumably because it doesn't have the bootloader set up correctly. Is it possible to rehabilitate it (with out buying a £25 programmer) or should I just bin it and buy a new chip?

loading a bootloader

I found this while spending time stuck in a hotel not far from you ;)

This describes how to burn a bootloader to a virgin ATmega328 using two jeenodes. I haven't checked the schematics yet but presume this can be done with a couple of roomnodes or roomnode/basenode pair too. It also justifies you spending some pennies on a couple of roomnodes or maye a roomnadoe and a basenode.
None of the HAH 328s that we ship have a bootloader. The reason for this is that the startup serial traffic from the Livebox can confuse the serial bootloader. Of course, the HAHnode 328s have a bootloader.
Probably easier to buy a new AVR that has been configured with an Arduino bootloader.
