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...

Thanks arriacinq but this is fine in my design.

The QuartusII programmer gets to 95% and then reports:

--- Quote Start ---

Error (209040): Can't access JTAG chain

Error (209015): Can't configure device. Expected JTAG ID code 0x02B040DD for device 1, but found JTAG ID code 0x00000000.

Error (209012): Operation failed

--- Quote End ---

Interestingly if I connect an old USB Byte Blaster to the JTAG header on the demo board (this automatically disables the embedded USB-Blaster-II) it works :confused:
