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 <-121>
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.


Sequence ID: 0
Error Code: -121
Error Class: 0x80002240
I/O Port = 240

Board Name: C5509A XDS510 Emulator
Cpu Name: CPU_1

Abort:                Close Code Composer Studio.
Retry:                Try to connect to the target again.
Cancel:                Remain disconnected from the target
Diagnostic:        Run diagnostic utility.
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
