cpu是stm32f103rbt6,软件mdk,之前仿真一直可以，最近频频出错，不是连不上目标板就是DEBUG运行过程中自己退出DEBUG模式

3.
Err Emulator has been changed or re-enumerated! 接下来错误Err No Cortex-M device found in jtag chain.please check the jtag cable and the connected devices.在接下来 Err flash download failed .target dll has been cancelled. 连接不上器件的时候进行仿真会出现以上错误
