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?
