I blew-up my Dragon. No, it's not the stupidest thing I've ever done. Buying Borland over µSoft and turning down an offer to provide artwork for royalities for a card game by a group of gamers going by the name of Wizards of the Coast blow this away.

Does anyone know what a BDR66KCO8Y is ?

Well, turning down an offer from the Wizards of the Sword Coast really humbles this. :-(

Can you get a replacement? Is BDR66KCO8Y the name of the dead part? Isn't it a small rectangular chip? Which part on the board is it?

Since we are back on power hungry dragons. I have a question/observation on my phoenix dragon. This is the one that came back to life after I upgraded studio.

Now it has developed some sort of new lust for the power of gold. When it is powered on and VTG is jumpered to VTRef the yellow light blinks. Removing the link to VTRef and the dragon works. Even when jumper between VTRef is restored the dragon continues to work and indicates 5 volts on the target. My guess is something is causing an overcurrent when the jumper is first connected. Nothing seems overly warm.

So why the flashing yellow LED?

Hello Daqq. I don't have a reference number for the part, and I've done some searches on the numbers on the top. No luck.

Jporter. VTG to VTRef is what killed it. Thanks for the note that I can pull it quick and get past the VTRef hurdle (when I get it working again I'll try it =^))

Where do you find these? Is it the JTAG connector?

VTRef is pin 2 on the ISP. VTG is the voltage on the power ground header. I have the dragon configured to work with Tiny25 chips, these use debug wire. I am not using JTAG.

The Manual for the Dragon says that it needs around 500ma to operate properly. That could be a problem for a lot of computers because most USB ports are only rated for 200ma max. I ran into the problem with one of my dells and my dell laptop could not do it at all. My solution was to make a dongle that supplied the +5 separately Since then, no more problem

Ok I don't see VTG but VCC on mine, I guess you have wired it up as per the example shown on the Dragon help file under "Devicesheet: ATtiny25, ATtiny45, ATtiny85" (pins marked A in Red). Are you powering up the T25 from the Dragon or a separate PS?

Pin 2 of the ISP header (VTG) should not take any power and does not have to be connectet once you start DW as you may already know...but of course you need to get there first :?

Very discouraging, js--none of the pictured Dragons would recognize my Mega88 via debugWire, whether attempting to work on an ASM or FORTH program.

If you get rid of that lazy cat in your avatar, the pictured Dragons might not feel so intimidated and actually start working for you.

Oh! Have you tried using Duct Tape & Bailing Wire to make the proper comms connection?

jgmdesign, the USB port specification is for 500ma maximum current draw. Not implying that all computers adhere to that though.
Lee, perhaps you need to write in Cymry?

How about being blown up by a Dragon.
