Hi Mathias K.,
You have this command buffer
4b 02 01 39 02 00 00 c0 04 3b 06 80 6b 01 81 4b 02 03
4b 02 01 / TMS shift no read
39 02 00 00 c0 04 / IN OUT 3 bytes read
3b 06 80 / IN OUT 1 byte read
6b 01 81 / TMS shift 1 byte read
4b 02 03 / TMS shift no read
This command buffer should return 5 bytes data.
There are no reason here the Amontec JTAGkey-2 do not send back the 5 bytes,
except if you have RTCK return clock enabled !!!
But a bad previous command buffer could corrupt the JTAGkey-2 ft2232 mpsse
interface.
Please send me the complet debug file .
Also, could you please try the same with Amontec JTAGkey D22X WHQL certified driver you found at
http://www.amontec.com/download/amontec-jtagkey-driver-d2xx-20091124.zip

Hello,
the send buffer looks okay. Maybe this is a timeout problem. Do you use the
d2xx or ftdi library?
