Problem when download FPGA SRAM OBJECTIVE FILE.

--- Quote Start ---

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.
