Hello folks. I am new to this forum, and in desperate need of pointers.<
Some background: I worked with an old avrdragon and Atmel (now Microchip) Studio the past several months. The chips: ATtiny 85 and ATMega328, with some other other types on deck. The dragon gave up the ghost last week.
I will miss the HVP, but I bought a new ATMEL ICE from the Microchip direct order site last week, and it arrived in the mail today. Microchip Studio recognizes the new unit, and upgraded the firmware the first time I plugged it in.
Now for the hair-puller. In Device Programming, MC Studio can't read the ATtiny85 (the only chip I've tried). I know the chip is good, and runs at 8MHz. The complaint is something to the effect that the chip power is out-of-range, with a subsequent "expected 0x00; got 00xC0" (or some such). I'm pretty sure that's a catch-all error, which I've often seen in the past, and have generally worked through.
But I can't work through it in this case. I've extensively re-researched ISP wiring basics, compared this wiring to the dragon's setup, etc., approaching the problem with increasing degrees of neurosis and paranoia.
All to no avail! Please do not assume that I skipped the User Manual; that's not to say I haven't missed something, of course.
So, advice, please! It is a new unit and the chip is known to be good (I have a USBtiny and USBasp, and used them repeatedly during testing). Have I overlooked something? Should I complain to Microchip. One other note: my multimeter shows 0.791V between Vcc and GND on the ICE ISP pins; the 'reported voltage' of the chip in Device Programming is 0.2V; I'm not sure whether any of that is meaningful.
Thanks in advance. -- Tarmin D.
