I have a broblem with programming fusebits... when I program fusebits on chip I cant't anymore re-program chip.
command line is;
avrdude -pm8 -Plpt2 -cstk200 -u -U lfuse:w:0xEF:m
only low fuse byte chanced (0xEF)
so there is no chance to program SPIEN (Enable Serial Program and Data Downloading), because it is in high fuse byte bit, 5.
Everything works fine, but re-programming flash is not possible.
avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
How I can re-program flash??
