尊敬的TI工程师和论坛的朋友们：
我们在配置MMWAVCAS-RF-EVM级联板过程中，遇到了SPI connect（3）无法通过的问题。具体地说，我们运行了Cascade_Configuration_MIMO.lua来自动配置，device1 和device2 均能顺利完成配置，当进行到device3时出现下面的报错：

尝试过手动配置，也出现了同样的错误。查阅了网络上各种论坛的资料，没能找到合适的解决方法，因此来求助各位，十分感谢！
Chris Meng：
你好，
请问你们使用的12V电源电流是否能支持5V？或者你们是否有尝试使用台式电源？请也确认两块连接紧密。

Zhongxing Wang：
感谢您的回复，我们使用的是简易学生电源，设定输出电压为12V，工作时电源上显示的电压为12V，电流在0.9A左右。不能确定您说的是否支持5V，另外您说的台式电源是否为手册上推荐的研华电源？
,
Chris Meng：
你好，
台式电源品牌不重要，台式电源通常提供的电流会比较大，你找一个有12V输出的台式电源试试。
,
Chris Meng：
Zhongxing Wang 说：电流在0.9A左右
毫米波对于峰值电流有比较高的要求
