I forgot to paste the debug logs: ------------------------------ tap state is RUN/IDLE DRSCAN type:1 start=RUN/IDLE goal=DRSHIFT in field 0/1 1 bits DR scan, 1 bits, end in DRSHIFT ------------------------------ tap state is DRSHIFT DRSCAN type:1 in field 0/1 1 bits DR scan, 1 bits, end in DRSHIFT Franck. ------------------------------------------------------------------------------ Monitor your physical, virtual and cloud infrastructure from a single web console.
