AVRISP MK II - works with avrdude, but not with avr studio 4

[jkerns]

OK, I know, just use AVRDUDE. Thanks. But...

I wanted to change fuses to change the clock frequency - load up AVR studio, tell it I have the AVRISP MK II, ATMEGA32 chip, try to connect and I get "Connect failed, select AVR programmer".

The light is green, I get a green flash when I plug in the USB...

Now, I try avrdude to see what happens.

That seems to work. I get lights flashing and the following (as an example)

M:\>avrdude -p M32 -c avrispmkii -P usb -v

avrdude done.  Thank you.

So, it seems to me that the device is hooked up OK and capable of talking to yea olde chip.

Now, I could just use avrdude to change the fuses, but it makes me nervous to work with the raw hex - it's been 20 years since I used to do that stuff... And it's bugging me that I can't get the AVR studio to work.

Any guess about what I'm doing wrong?

Oh, and I've tried two different AVR ISP mk II programmers.

Have You tried AVR Studio 5 or Atmel Studio 6?

All AVRDUDE is telling you is that your computer can talk to the AVRISP. You've told it on the cmd line that its an ATMega32 chip, and it has found the programmer.
Don't think it proves that the programmer is talking to the chip.

Looks like you're using AVRDUDE on a PC - in which case it will have been compiled with its own libusb.dll support. It could be that AVRStudio can't find the libusb drivers or you have installed over the top of the ones that AVR Studio installs.

Thanks.

I tried installing AVR studio 6, uninstalling the driver for the AVRISP mkII, letting it re-install - no luck.  I assume that it must be that AVR is using a different driver that is not actually connected to the programmer.

I guess I'll just work with winavr / avrdude for now. That has worked for me before for programming this chip. I just need to track down the bit by bit data on the fuses...

Thanks for the suggestions.
