我用的是xds510仿真器，板子买了一个多月了，之前仿真的时候一直没有出现问题，可以连接仿真，今天就不能连接，报错信息为
rror connecting to the target:
Error 0x80002240/-121
Fatal Error during: Initialization, OCS, Control,
This error was generated by TI's USCIF driver.

SC_ERR_CMD_HANDLE &lt;-121&gt;
A bad controller handle has been given to a function,
either before attempting to open the controller, or after
having opened the controller and ignored its error status.
Valid controller handles are generated when attempts
to open the controller return a clean error status.

Error Code: -121
Error Class: 0x80002240

百度了一下，说是仿真驱动有问题，但是设备管理器显示的都已经安装好了，哪位知道的帮忙解答一下，我学的是C5509，这个问题不解决，后面的学习就没法进行了，多谢各位了
