I bought a pair of the AVR 28 Pin 20MHz 32K 6A/D - ATMega328 processors, not really paying attention to the fact that they were 20Mhz, more is better, right? Well, once I realized they are not supported arduino processors, I have been attempting to use them with 16MHZ crystals. I thought this should work, and I could use an arduino in Arduino as ISP. I have checked the voltage on the processor and that seems correct.
All I can get is the message: avrdude: stk500_getsync(): not in sync: resp=0x00 and no diagnostic.
I have tried with 16MHz crystal and with a 16MHz ceramic resonator and I always get the same result.
Is there a way to find out what is going wrong?
Or am I wasting my time and should just go and buy the 16MHz processor?
