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? 芯片挂了
