新做的一块板子，芯片是6701，上电时钟正常，连接仿真器的时候报错，错误如下：
C6701_0:Error connecting to the target (Error -235@0xFFFFFF15),The data scan-path connot circulate bits,it may be broken. An attempt to scan the JTAG data registers has failed the target's JTAG data path appears to be broken with a stuck-at-one or stuck-at-zero fault (Emulation packge 5.1.237.0)
