错误信息如下：
!Error: JTAG chain problem detected
!Error: TDI connection to the first detected device EP3C(10|5)/EP4CE(10|6) might be shorted to GND
!Error: The TCK and TMS connections to the device before the first detected device EP3C(10|5)/EP4CE(10|6) might have a problem
!Info: Detected 1 device(s)
!Info: Device 1: EP3C(10|5)/EP4CE(10|6)

有没有碰到过这种错误的？
