when use Quartus II software and select Tools > Programmer to download .sof instance file .

coming:

Info (209060): Started Programmer operation at Wed Nov 06 17:58:42 2013

Error (209031): Device chain in Chain Description File does not match physical device chain -- expected 1 device(s) but found 2 device(s).

Error (209012): Operation failed

Info (209061): Ended Programmer operation at Wed Nov 06 17:58:42 2013

the device is auto detected .

where is the problem？

As I see you are using Arrow SocKIT dev. board.

- Configure FPGA board properly ! (SOCVHPS is missed from your actually detected chain)

- Reset FPGA (try warm, hard, and FPGA reset)

- Hardware Setup -> CV_SOCKIT

- Auto detect chain

- Change file -> browse for .sof (which contains the same FPGA device as 5CSXFC6D6)

- Finally, Program FPGA

alternatively, try

Quartus -> Tools -> JTAG chain debugger -> Test JTAG chain

thank you so much!

i set jtag clock speed at 16M, the follow:

- Auto detect chain

- Change file -> browse for .sof (which contains the same FPGA device as 5CSXFC6D6)

- Finally, Program FPGA

it works.
