Thank you all for your helpful advises.

I have checked out the schematic of the header and it turned out there were 12V power supply pins aligned right next to the normal I/O pins.

Obviously I have touched this pin with some normal pins and it have destroyed the I/O pins.

But luckily enough, I could still program the FPGA through JTAG. And I found a solution by substituting the former used pins with others.

But anyhow, some part of the development kit seems broken, with the error LED still flashing.

Thank you all again for the help that I really appreciate. Have a nice one!
