JTAG Communication error

Hi,

I am programming my Stratix V FPGA board and using the 'In system memory content editor' to change the parameters of my design in real time. But as I try to write the parameter values in the memory I see JTAG communication error. Please see the screenshot. Any help will be appreciated.

Thank you.

    From the error message, seems like the device selected is not correct. Can you try to select the correct device with correct part number?

      Hi,

      I checked for the device name but it is correct. Also the error does not come up every time.

        Is this intermittent issue? As in the JTAG communication passed and failed between intervals.
        Or is there any specific action that you execute that could cause JTAG communication error?

        The possible causes that this error pop up is that the communications cable, such as the ByteBlasterMV or ByteBlaster II cable, is no long configured or connected. Or you specified a device that does not match the device on the circuit board. As a result, this tool cannot conduct any JTAG communication with the device.

        I am suspecting this could be hardware issue. Have you try to program using different cable or device?
