使用例子里的程序测试，全部按照指导进行了配置，但是debug会有错误，无法进行下载：
Error connecting to the target:
Error 0x00001200/-1041
Error during: OCS, Target,
Device driver: Problem with the Emulation Controller.
It is recommended to RESET EMULATOR. This will disconnect each
target from the emulator. The targets should then be power cycled
or hard reset followed by an emureset and reconnect to each target.
我该如何做？
