So, finally the problem is solved. It appears, that chip was somehow burnt, so simply dead and not responding. Solution: changed chip, and burnt bootloader. And now it works again. I would recommend, next avrdude command to identify burnt chip: ./avrdude -c usbasp -p atmega328p -C ../etc/avrdude.con...

Hi Stanley, I have bought USBasp, connected its pinouts (SCK/MISO/MOSI/RST/5V/GND) with the respective ones on Freematics board, but when I try to burn bootloader from Arduino, I get the error message: avrdude: auto set sck period (because given equals null) avrdude: warning: cannot set sck period. ...

Hello Stanley, Ok, I have bought USBasp, connected all six pinouts (5V, GND, SCK, MISO, MOSI, RST) and still no luck. When I try to run next command: ./avrdude -c usbasp -p m328 -C ../etc/avrdude.conf I get next: avrdude: warning: cannot set sck period. please check for usbasp firmware update. avrdu...

Hi Stanley.

Could you suggest the proper scheme of connection USBasp with pinouts, please? I have found several in internet, but not sure which one is right. I'm sure you have done this before, so would like to check with you.

With regards.

I have used default Arduino IDE, but then switched to Sloeber IDE, it's Eclipse-based IDE for Arduino development which is much more convenient. I didn't upload on it f...
