Cyclone V - JTAG ID Error - download failed

Hi, I meet JTAG error while downloading the .sof file to the FPGA via "Programmer". It says that the JTAG Id isn't what the Programmer was expecting for. I use Cyclone V devloppement kit...

I am seeing a similar problem with the Cyclone V GT demo board, annoyingly on the GT demo board you have to have the MAX V CPLD system controller in the JTAG chain with the FPGA which is not like the GX demo board.

When I scan the JTAG chain it automatically detects the FPGA and CPLD correctly but when I try and load a sof in the FPGA and bypass the CPLD it fails.

Does anyone know how to resolve this one?
