this patch - JTAGBv3.patch - it goes on top of what urJTAG? V0.10 or the head from svn or ?

is this the cumulative patch? (does it contain all the changes from the "other" thread)?

After we patch it with this patch, will BBv2 be able to burn its own cpld? (interface=2?)

attm with 0.10 (no patches) if nothing is connected to the bbv2 I get

Code: [Select]
jtag> cable jtagkey
Connected to libftd2xx driver.
jtag> detect
Warning: TDO seems to be stuck at 0
jtag>

With latest trunk from SVN (UrJTAG 0.10 #1902) it works without a patch:

Code: [Select]
jtag> cable jtagkey interface=0
Connected to libftd2xx driver.
jtag> detect
discovery.c:117 urj_tap_detect_register_size() Warning: TDO seems to be stuck at 0

I just received it from seeed and I missed on the communication about it so it's being slow catch up

so the question is - should I svf the BBv2-JTAGkey-v1.1.svf.zip from this thread and is the JTAGBv3.patch still relevant as it seems that latest trunk knows how to parse interface ?

The latest version is 1.3 or so. There is a new BB download package here, the bitstreams are there:
http://code.google.com/p/dangerous-prot ... e.v2.0.zip

I'll clean up the forum shortly, sorry about the confusion.

Our patch is in the urJTAG SVN latest version now. Latest SVN should support the secondary interface no problem.

Technically the CPLD interface is FT2232 type, but the 4 important pins are the same so it shouldn't matter much.

donno how I missed the google code repository .. probably because it is 6am now .. will go there to pick up the slack .. and eventually look at the source of the cpld core :)

great that the patch is now in the svn .. hopefully they will release 0.11 soon :) but looking how good the darn thing work they might decide to go 1.0 :)

There is a schematic and VHDL version of the jtagkey buffer.

urJTAG is a great program.

For anyone who stumbles onto this thread later, here's the list of the latest cores:

I just bought the V3. I must say though the site and resources are pretty unorganized. Lots of links that bring you in circles.  I have a hard time trying to find the right version of the svf to load, and the proper version of UrJTAG to use. Getting kind of frustrated with this thing.
