Hello - I built a simple ATTINY841 board with a 14.7456MHz crystal (bypassed by 39pF caps). The processor is a virgin out of the package from Digikey, so I assume there are no fuses set yet. I'm powering the processor from a 3.3V supply. I'm running AS 7.0, using an genuine Atmel ICE programmer over 6-pin ISP. I have a 10k pullup on the RESET line.
When I try to either erase the processor or program fuses, I get "Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool"
I tried to see the oscillator running with an o'scope, but pins 2 & 3 are deader than Julius Caesar. The 1st 2 LEDs are lit on the programmer, but not the 3rd (guess that means "Target is stopped").
I checked the pinout of the 6-pin ISP connector, it matches a board I bought that works.
Anybody got any ideas? much thanks, paul
