How to programm Arduino 2560 using Arduino UNO as ISP

Googmorning,

please, is there a way to programm my Arduino Mega 2560 (and change its default bootloader) using an Arduino UNO as ISP? I had to insert watchdog feature, so a I recompiled bootloader and now I've to burn it but I've not any external programmer!
Searching in google, I've found lots of link and web page but no clear guides or tutorial...

Thans in advance :slight_smile:

Try this one: Gammon Forum : Electronics : Microprocessors : Atmega bootloader programmer
It's from Nick Gammon, a mod here on the forum. It's very clear and well written. (and it works well too..)

Thank you very much ReSiStAnCe, I'll try it :wink:
