so i followed this tutorial EXACTLY: http://arduino.cc/en/Tutorial/ArduinoToBreadboard
at first I had the wrong crystals but then Lefty in the forums here helped me out and I got the right ones...I have 6 atmega328p-pu chips...I put the arduino bootloader on all of them no problem. Then I started putting some blink sketches on the atmegas while they were in the breadboard (no chip on arduino board)following the second part of the tutorial...that worked fine too for awhile. I got to the 4th chip, and I got the error message that you get when the board can't find/recognize the chip:
avrdude: stk500_getsync(): not in sync: resp=0x00
avrdude: stk500_disable(): protocol error, expect=0x14, resp=0x51
5th chip did that too, 6th chip the sketch uploaded.
So I thought I had some bad chips.
But then I was playing around a little more, uploading different sketches to different chips and slowly I was getting that error message more and more and now I get it on all the chips. Even on the ones that previously took the blink sketch just fine....(I did not change any wiring...everything was exactly the same as it had been before)
when I plug the atmegas directly into the arduino board I can upload sketches to them fine.
So this isn't a huge problem as I can do what I need to do...I'm just popping out and placing the chips more than I'd like to...it's just a weird problem. I see that some people are having similar issues here...
Is this a common problem?
I'm on windows 7 64x using arduino 0021 on a duemilanove
thanks for any input!
