after soldering, most LEDs went on. With touching some pins of the attiny the on-LEDs change in a random way. May be, that touching the clock input of the serial->parallel latches causes this behavior.
I re-soldered all contacts, checked them more than twice... but no change.
So I assembled the serial programmer and tried to download the firmware (read from chip):
I think this worked fine.
Code: Select all

Now my question - can it be that my ATtiny2313V came without firmware?
Can I burn the firmware to it with this command?

avrdude -c dasa -p attiny2313 -P /dev/ttyS0 -U flash:w:spokepov.hex
