Re: The TDO stuck at 0 problem

I got my Bus Blaster today, and I'm also experiencing this error.
I'd like to point out that whenever the wiki instructs you to install the modified urjtag exe, or to run a self-test .bat, it does not actually link to anything.
After some time I found these all on svn. Also xc2c32a.bdsl, which was well hidden in:
./manufacturing_resources/v4.1/Programming/bsdl/xc2c32a_vq44.bsd
(EDIT: after writing this I've found the main package with urjtag and .bsd, which is nice).
Anyways, in my case self-test was okay, so maybe the error is normal and there is something wrong with my target connection (LPC1769)

EDIT: after various voodoo rituals, it's now working (I think). So false alarm from me.
