Mega 4808 and Optiboot bootloader

Posted on

The Mega 4808 can normally programmed over UPDI. The UPDI Interface is great, you need only one data wire and ground, but in some cases you wanna program the microcontroller at your board and you don´t want to make a UPDI Programmer on this board. In this cases you can use a bootloader for programming.
