Hello!
I have try to update the Koryuu with an Atmel Avr ISP MKII but I failed 🙁 (AVRDUDESS didn’t see the controller inside the Koryuu )
Perhaps a voltage problem with the jumpers at the down left part of the programmer?
May I used Microschip studio software (Programming tool module) instead ? It’s seams to see the correct controller inside the Koryuu but I’m afraid to lost the internal firmware in case of failure so I prefer to ask you before I try. Can I try directly without any modification of the PCB/connectors or should I made something before ?
Thanks a lot.
Regards
