我用的是DM642的DSP，仿真器是XDS510，在debug中connect的时候，总是会出现下面的问题：

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

选Simulator是软件仿真，只在电脑上运行；选FET Debugger是硬件仿真，会刷到芯片中。

你好！ CCS 是正版的吗 仅代表个人观点，不喜勿喷，谢谢。
