This is probably something dumb I'm doing. I assume this is equivalent to powercycling the chip? Or is it needed for programming? Is there some way I can verify the connections? I haven't connected reset. ![]() Right? Maybe I need a resistor on DI? I'm really unfamiliar with AVR. I've tried using 3.3V as well, but I think because I'm using a 16Mhz oscillator that I need 5V. ![]() ![]() I've made some slight changes to the programmer source (attached) mostly just to move the SCK to pin 14 so I can see the LED blink. usr/local/CrossPack-AVR/bin/avrdude -c arduino -p m328p -P /dev/tty.usbmodem12341 -b 19200Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x14Īvrdude: stk500_getparm(): (a) protocol error, expect=0x14, resp=0x10Īvrdude: stk500_initialize(): (b) protocol error, expect=0x10, resp=0x01ĭouble check connections and try again, or use -F to overrideĪvrdude: stk500_disable(): protocol error, expect=0x14, resp=0x10
