Hello!
It's been now 10 hours trying to get my ATmega328P-PU chip to work. By work I mean that I can upload a project on it and use it as a standalone chip for my project ( So I don't have to buy a complete new board JUST for my project). My main board that I'm using is (Arduino UNO-Funduino with ATmega328P-PU). For my project (Dot matrix real time clock) I don't want to use my existing ATmega328P-PU chip that is already on my main board BUT instead I bought another atmega chip from ebay.
http://www.ebay.co.uk/itm/251597436422?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT
On ebay it says that this chip has bootloader already installed and it's ready to accept sketches.
So I folowed this tutorial, how to upload sketches to the external chip.
The problem is that I get this error:
Sketch uses 450 bytes (1%) of program storage space. Maximum is 30,720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2,039 bytes for local variables. Maximum is 2,048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I have tried every board and every procesor that is avaible in the IDE and it never worked.
I have searched a good 2 hours on google and youtube for a solution and I read somewere that the reason why I can't upload a simple sketch is because of the wrong bootloader versions or something like that. So I tried to rewrite the bootloader and this is probably the closest I got to make it work:
avrdude: Yikes! Invalid device signature.
Error while burning bootloader.
Double check connections and try again, or use -F to override
this check.
I'm stuck now and don't what else to do. Did I bought the wrong atmega328 chip? Do I have to buy an AVR programmer to fix the bootloader?
and if somebody knows a wesite that sells ATmega328P-PU chips that have a working bootloader for UNO board.
I'm new to the arduino world and I try to learn to use it to make awesome projects
Thanks for any advice in advance.
Best regards!! BoskoSLO
