I have found that the wrong MSEL connections were causing this issue: "Error (209014): CONF_DONE pin failed to go high in device 1".

Cyclone IV E, MSEL[2..0] = 001 was not overwritten by JTAG connection. Therefore JTAG was unable to program the device. Maybe the datasheets should reflect this.

After correcting the MSEL[2..0] = 010, the JTAG became responsive.

James.
