FPGA jtag接口，TDI莫名与3.3V短接，与GND电阻仅有600-700K

FPGA jtag接口，TDI莫名与3.3V短接，与GND电阻仅有600-700R
提示错误：
Error: The TDI connection to the first detected device EP2C5 might be shorted to VCC or is an open circuit
Error: The TCK and TMS connections to the device before the first detected device EP2C5 might have a problem


而AS正常。
排查PCB都没问题。芯片应该是原装。

有没有办法救活？
