各位TI技术支持社区工作人员你们好！最近我在使用MMWCAS-DSP-EVM以及MMWCAS-RF-EVM两块开发板利用mmwave studio在级联模式下进行雷达数据采集时，遇到了如下问题：
向开发板下载配置时，使用的是官方提供的Cascade_Configuration_MIMO_Test.lua脚本进行配置，Device1、2、4均配置成功，MMWCAS-RF-EVM上的对应指示灯也依次亮起：

[11:47:30] Status: Failed, Error Type: RESP TIMEOUT

[11:47:34] ***Script completed successfully.***
请问这是开发板的什么地方出现了问题呢？或者说需要检测开发板的哪一部分电路的功能来确认检查上是否出现了问题？
