Bus Blaster JTAG debugger / Re: Bus Blaster V3 TDO stuck at 1 Continued...
I just wanted to chime in on this and first of all thank you for figuring out the UrJTAG driver problem (jtagkey instead of ft2232) and then of course providing the modified JTAGkey buffer logic.
It seems like I got lucky to download and reupload the modified bitstream to my server as it does have some uses.
I originally got my BB in order to program a Lattice MachXO CPLD I've got on a dev board. As it turns out the dev board also had an FT2232 on it before I accidentally made it release the magic smoke (oops).
Long story short, the modified buffer logic makes the BB work with the Lattice Diamond design software programming solution, i.e. you can program Lattice CPLDs directly from Lattice's official software.
I presume I could've just used the unbuffered 3.3V JTAG connector on the side instead of reprogramming the buffer? Anyway with the modified buffer logic I could also have a 1.8V JTAG interface working with the Lattice software directly.
Unfortunately I can't link to my blog post as it complains about me as a new user being a spammer.
EDIT: I just saw that you've uploaded a new bundle with the bbv3-passthrough.svf which also works together with the Lattice design tools.
I am already linking to the thread, may I reupload that .zip to my server so that I can link to a known good version (preventing dead link problem)? Of course I will attribute you for making those changes ;)
Cheers,
