If you find this pin, its okay. On design I use GPIOL3 ;) The PCB of the
OOCDLink with RTCK support is laying in front of me, but I ran out of
FT2232Hs to assemble it, so I have to wait until I get the ic from the
dis

That is obviously true.. but you really helped to make things more clear.

So the JTAG-debugger needs an input pin attached to RTCK. OpenOCD has to
monitor the state of this pin an wait for a falling

Thank you Duane for your super fast reply!
My dongle is pin compatible to openocd by now (I just added high speed level
shifters to support targets from 1.2V to 3.3V with TCK speed greater than
30MHz). You said I'd have to set jtag clock speed to zero to enable adaptive
clocking, ok, but as I am

FYI - the XVERVE -signalyzer has this "built in", as does many of the
SEGGER dongles, do check, you can screw up a target board easily enough.

The "FT2232H" is already supported :-)
See the configure option:
--enable-ftd2xx-highspeed
Enable building support for FT2232H and
FT4232H-
This is my first posting to this mailing list, so I friendly say 'hello' to
everyone :-)
I am working on a OpenOCD dongle based on the FT2232H. I want to support
adaptive clocking, but I don't know how to accomplish this task. AFAIK there
are no FT2232 based designs with this feature available.
