关于仿真器找不到设备的问题(could not find device)

Other Parts Discussed in Thread: MSP430F5358

系统是win10 64bit IAR是7.10.1,仿真msp430f5358芯片,仿真器是 MSP-FET430UIF 提示“Fatal error: Could not find device (or device not supported)   Session aborted!”

还有一句警告Warning: The memory names defined in the device description files must be unique. 'RAM' is used more than once. This is not allowed.
