AWR1243: 级联AWR1243+TDA2时钟同步及数据采集问题

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？

您好，

我们测试了下1.8V/1.2V/1V等电压值是正常的，当前在Studio（通过LUA脚本也是这样）上配置主芯片的ADC channel & configuration时，在output里面会提示未知错误，如下红色标记log，黄色标记为配置从芯片出现的错误，主芯片的固件可以下载，请问此处ADC config可能是由于软件配置的错误还是硬件芯片哪里异常才导致的错误呢？

此外，我们测试了下主芯片的OSC_CLK_OUT，没有时钟信号输出到从芯片，因而从芯片一直配置不成功，固件下载不进去，这个是不是主芯片上面的工作有异常导致从芯片没有时钟输入呢？如果单独接一个时钟给从芯片是否可行？

针对硬件的修改，当前都是基于四片级联的那个开发板去做的，去掉了AWR3和AWR4及相关接口，其他的没有做大的改动，但是我们射频板（Pin脚数和TDA2开发板连接器不太一样）有通过一个转接板接到TDA2开发板AWR1和AWR2的接口，这个应该不影响芯片的正常工作吧，射频板与处理板信号通信正常就可以把，麻烦帮忙看下上述问题，非常感谢。

 AWR2243 Checklist for Schematic Review, Layout Review, Bringup/Wakeup (https://www.ti.com/lit/zip/sprr419)

主芯片我提到的这些电压，你有测量过么？看表格里bringup里的相关信息。

Kun Wang 说：

作为测试是可以的，请参考数据手册了解输入时钟的要求。

对于级联工作，还是需要master提供时钟给slave，要保证一定的同步。

您好，

这些电压已经测过了，看着电压应该正常的，我们会再仔细对比下chick list里面各项是否正常；

当前的问题首先是下载完主芯片的固件之后，设置ADC config时会出现未知错误，这个除了电压还可能有其他哪些因素会影响此处的配置呢，芯片有可能没有正常工作是吗？

此外，这个ADC config的错误是导致主芯片OSC_CLKOUT没有检测到时钟信号的直接原因吗？

谢谢。

你好，

从ADC config的错误我只能看出AWR2243没有正确的相应，但无法判断错误的原因。

好的，谢谢，那这个ADC Config的配置有可能是发射或者接收链路哪里硬件的通信问题吗，固件下载是成功的，接下来ADC config设置的时候就会出现这个未知的错误，这个ar1.ChanNAdcConfig_mult函数里面的配置是通过硬件什么接口配置写进芯片的呢，看看是不是哪里接口通信异常，谢谢。

AWR2243和host通信的接口就是spi，你可以测量一下spi的相关信号，看是否良好。

你好，

注意量产版本的AWR1243是不支持级联的，AWR2243也只有后缀带P的支持级联。
