    Unfortunately, the JTAG buffers I'm referring to are in the Cyclone II device. If the board no longer auto-detects (but previously did) then one or more of the four JTAG pin input/output buffers is likely to have failed. This is most likely due to static damage or accidentally over-driving them.

    Cheers,
    Alex

    Oky, if JTAG is faulty. Is their any other way I can program the board? Means any other interface other than JTAG for flashing the processor.

    See the "PS Configuration Using a Download Cable" section in the "Configuring Cyclone II Devices" chapter of the handbook - page 13-48 and refer to figure 13-19.
