using avrdude 6.3 for linux
mcu is attiny4
programmer is AVRISPMKII
Using avrdude 6.3 in linux...
I can clear any of the "configuration byte 0" fuse bits using avrdude, but I cannot set any bits...
example, I can write 0xFE, but then I cannot write 0xFF.
Tried in High Voltage and Normal Voltage programming modes.
Also tried clearing chip first, still no dice.
sudo avrdude -p attiny4 -c avrispmkII -B 50 -q -q -u -U fuse:w:"0xFE":m
//this does not work, cannot set bits, only clear them, returns mismatch error blah blah "0xFF does not equal 0xFE"
sudo avrdude -p attiny4 -c avrispmkII -B 50 -q -q -u -U fuse:w:"0xFF":m
Using AVRStudio everything works fine, I can clear and set bits.
Does anyone have any ideas? Maybe I am doing something wrong? or maybe a bug in avrdude?
