您好,我的开发板型号是MSP-EXP430G2,在我将开发板与电脑连接之后没有COM4程序下载的串口,如下图所示,是怎么回事?
在我的电脑重启之后在CCS里面可以识别到,但是一会儿之后就识别不到了

您好,
正确识别结果是评估板用户手册“Figure 7”中所示,如果只有"MSP Application UART1",
由于eZ-FET是完全独立于MCU,请检查USB口供电能力是否足够(Figure 6)。
板上的LED灯状态如下:The green power and yellow LDO LEDs should illuminate.(1.4.1 Connecting to the Computer)
