Thank you very much for your super fast reply! My dongle uses an 'oocdlink' compatible pin out by now (I added some ultra high speed level shifters to support targets from 1.2V to 3.6V with TCK speeds greater than 30MHz). But at the moment I don't use the RTCK signal from the target. You said I'd have to set jtag clock speed to zero, to enable adaptive clocking, ok, but my problem is how to tell OpenOCD what the current target speed is.
