My brand new, out of the box AVR Dragon is giving me a strange error.
I have installed the USB drivers it needs, and done a firmware upgrade of the Dragon from AVR Studio - all without a problem.
I can connect to it from AVR Studio 4 (Tools -> Program AVR -> Connect...). I select AVR Dragon over USB. The dragon flashes for a moment and then it's connected. This is just as it should be - I've been using a different Dragon elsewhere, without problems.
When I try to select the "board" tab it displays the following status information:
Getting revisions... OK! Reading target voltage .. OK! Getting ISP frequency parameters.. FAILED!
If I try reading or writing the ISP frequency it gives me the same error.
I don't have anything connected to the Dragon - not a single wire. Shouldn't it work anyway? I have seen it work before (with another dragon).
AVR Studio 4.13 build 528 on Win XP, Core 2 Duo machine.
Board tab reports Revision Hw: 0x0102, Sw: 0x0101 0x0109
I have uninstalled and reinstalled everything I can think of at least twice - no difference.
Any ideas on why it doesn't work?
