DCA1000EVM采集数据时报错Unable to read GAFF Version.

你好，我在使用AWR1642+DCA1000采集数据的时候，出现错误。使用mmWave Studio02_01_01_00，connection选项没有问题，都能正确连接，Static Config、Date Config也没有问题，在Sensor Config里点击Set Up DCA1000时报错

错误代码

一个月前用过这块DCA1000采集数据，没有任何问题，fpga版本号是2.7。这次使用的时候报错，同一个电脑同样环境换了另外一块DCA1000可以正常采集数据。请问这个问题有可能是什么原因导致的？要怎么解决这个问题？谢谢
