For a year ago I disambeled this pcb from a home product to reengineer the the IO ports on the UC. I then meantime i did a temporarily PCB with a Arduino nano. My plan was to write a new firmware on the original.
But time went and I didn't finalize the project... But now it should be, so started up again and have now clarified all the pins in this Atmega16. The problem is that I cannot get any communication to work. I cant even manage to get a device ID from it. I have tried with a USBASP and my Atmel ICE, nothing works. only get avrdue command:
As you can see there's a 10 pin ISP programming port which is the only one i have used.
Is there anything I should try before having someone to replace this Atmage16 from the board? a new control board is 150Euro..
the onboard krystal is a 8mhz and the Atmega is of type Atmega16 16AU, 0612J
