TI专家好
当前我们做了个两片级联的射频板，想搭载TDA2通过Studio做数据采集验证，但是在studio上下载固件时只有master芯片可以正常下载，如下，从芯片的SPI connect没有反应，无法下载固件，我们用示波器测量了下，好像从芯片的时钟信号没有同步过去，如下第二图红色链路，此处主芯片的OSC_CLKOUT没有测量到同步信号输出到从芯片，请问如果通过studio这样去下载固件还需要做其他的一些软件接口的配置使主从两芯片都能正常工作吗？
此外，我们修改了ti\mmwave_studio_02_01_01_00\mmWaveStudio\Scripts\Cascade里面Cascade_Configuration_MIMO.lua为两片级联的模式，通过lua脚本直接写入下载，但是在主芯片函数运行到ar1.ChanNAdcConfig_mult时会报未知错误，如下log，请问此处可能有何原因会导致Master : Channel & ADC Configuration Failed呢，此处报错之后Cascade_Configuration_MIMO.lua里面后续从芯片的初始化、SPI连接、固件下载就都不会运行了，麻烦帮忙看下此处Master : Channel & ADC Configuration Failed和上述OSC_CLKOUT同步时钟信号是否有啥关联，该如何配置解决此处的报错问题呢？

谢谢。
Chris Meng：
你好，
感觉芯片工作不是很正常。在RF power up后，你能否测量一下下面checklist提到的几个电压值，看是否正常？
AWR2243 Checklist for Schematic Review, Layout Review, Bringup/Wakeup (https://www.ti.com/lit/zip/sprr419)
你们硬件上TDA2复位AWR2243的号是否有保留？你们的硬件上除了去掉两片AWR2243，比较4片级联的参考设计还是否有其他裁剪？
