I am trying to burn a simple blink sketch on 3 different mini pro without luck. This is the error I get:
avrdude -c usbtiny -P usb -p m328p avrdude: initialization failed, rc=-1 Double check connections and try again, or use -F to override this check. avrdude done. Thank you.
I tried it on nano ICSP with the same microcontroller and works just fine.
For the record, this is the wiring I use right now:
GND → GND
VCC → VCC
SCK → 13
MISO → 12
MOSI → 11
RST → RST
I also tried reversing MISO with MOSI.
Any ideas what could go wrong?
