Bus Blaster JTAG debugger / Can Bus Blaster v3 emulate Xilinx USB jtag?
Hi,

I've gotten my v3 to work with urJTAG under Windows, but I think it would be more productive to use it directly with the Xilinx tools (impact, etc.).  I know there is some open source driver for Linux, but is there any solution for Windows?

Thanks,
Crawford

Project logs / Nixie Tube Thing - Dirty PCB to the rescue!
[attachment=0]Folks,

I have been lusting over the Nixie Tube Driver that Ian brought to the 2012 World Maker Faire.  When I met him there I asked about board production, but he explained it was a one-time thing.  Fair enough.

Well it's 2014 now and DirtyPCB exists.  I grabbed the design off the forum, and shot it off to DirtyPCB for fabbing.  Attached you'll see the first build driving some old nixies I had in the vintage drawer.

I dropped the PCB design in the DirtyPCB store.  (Of course, I take no credit for the design - it's all Ian).  If you want some, go buy some!

Thanks Ian! Thanks Open Source Hardware! Thanks DirtyPCB!

Happy New Year All !

Bus Pirate Support / Another Motherboard bios save (BusPirate + Flashrom = FTW!)
Folks,

(I know this has been done before, just wanted to report success if anyone else wants to do this).

I was able to save a motherboard using Buspirate and Flashrom!

Background:

A friend gave me a Gigabyte EP35C-DS3R motherboard, that had succumbed to the dread 'infinite reboot' issue.  The Interwebs reported this was usually a bad bios, so I decided to re-flash the bios using the great write-up here: http://www.freneticrapport.com/2010/10/how-to-restore-bios-after-bad-flash.html

I tried to do the flash directly on the mobo with no luck, but the bios was on a SOIC 8-pin, so I desoldered it and did a quick nest-of-wires like so:

After re-soldering the bios chip back in, it booted up right away:

I'm really happy with the results (and saving the cost of a new motherboard). 

Thanks Dangerous Prototypes and Flashrom teams!

General discussion / Anyone going to Maker Faire NYC?
Dangerous Prototypers,

Are any of you going to make it to Maker Faire NYC this Sat/Sun Sept 25-26?

I know that Ian mentioned he *might* go to the Open Hardware Summit, and MF/NYC is just a couple of days later.

Bus Pirate Development / JTAG Support - gone?
Folks,

A while ago, I tried to get JTAG working on my BusPirate with OpenOCD in Windows.  I got as far as realizing that I really needed to use Linux for it all to work and put it aside.

Now, after several firmware updates, I can't find JTAG menus at all, unless I'm being really stupid (quite possible).

Is JTAG gone?  Is it gone for good, pending the BusBlaster that seems to have JTAG as a primary function?
