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...

Hi guys,

Actually, my former problem is solved.

JTAG ID Error occured because of unconstrained in/out of my design.

To avoid it, make sure that all your in/out have a pin_location assigned.

regards,
