I've installed bootloader (Optiboot) to my 1284P
I chose 'Mighty 1284p 16MHz using Optiboot' as board, 'AVRISP mkII' as Programmer
and I wiring breadboard as picture below but I can't upload a sketch
I got error message "Third-party platform.txt does not define compiler.path. Please report this to the third-party hardware maintainer."
Could you please advise? (I don't have FTDI cable)
