ATMega328P-UP bootloader

Other Hardware 3rd Party Boards
1

I had 5 microcontrollers ATMega328P-UP and I started reading this tutorial for creating a bootloader on them: Gammon Forum : Electronics : Microprocessors : How to make an Arduino-compatible minimal board

Now I have two problems.
1 - I was trying to achieve the 16MHz version, so I've pressed "U" then "G" then it got stuck and my Arduino UNO could not find that microcontroller anymore.
2 - It successfully worked for 8MHz (with another microcontroller) but now I have the question: How to program it using Arduino ISP ?

Thanks

PS. I've attached the log from 8MHz version

By selecting the right chip in Tools > Board and then "Upload with programmer".

Read this: http://arduino.cc/en/Tutorial/ArduinoISP.
BTW: Did you mean ATmega328P-PU? Please, correct this to avoid confusion (I had to look if -UP really exist, some new package). :wink:
