I'm trying to program an atxmega32a4u. I have a dapa cable, RS-232 to TTL serial converter, and an atmega328p.

Is there any way I can program this atxmega32a4u using what I have available? I do not have an AVRISP-MKII/avrasp however it seems like I could use an atmega328p and the RS-232 serial port instead of USB. Has anyone maybe created a version of the LUFA PDI firmware (AVRISP-MKII clone) that works with an atmega328 over the serial port?

No.

Why not just buy a real AVRISP-2 ?

Or a Dragon / JTAGICE-3. In which case, you could debug as well as program.

Incidentally, have you checked whether the atxmega32a4u contains a DFU bootloader?

In which case, you could upload your software via FLIP.

David.

Well obviously a "proper" programmer would work but then I would have to pay for a proper programmer and wait forever for it to get here. ;) I believe I already have everything I need to get the job done. I'm just wondering if I need to write the tools to do this myself or if someone already has.

Yes I checked and the chip is completely blank as far as I can tell. :(
