TDA3MV: TDA3MV串口Usecases配置问题

TI专家好，

当前我们在自己开发板上通过CCS或者QSPI方式均可以下载TDA3x固件，两种方式下启动串口的输出及配置选择还有一点问题想请教下：

1、Load From CCS

参考VisionSDK_UserGuide_TDA3xx.pdf，通过CCS方式，下载运行各核后，串口有输出及Usecases的配置选项如下图，但是我没有办法选择这几个选项，没有办法选择需要运行的use cases或者系统配置等，串口输出的Log如图片下的信息，Log中有出现“src/bsp_deviceI2c.c @ Line 667:
[IPU1-0] 41.161532 s: I2C0: DEV 0x20: ERROR !!!

等错误，请问是这些问题导致的串口不能进行选择配置吗，该如何进行修改呢？

2、Load From QSPI

参考VisionSDK_UserGuide_TDA3xx.pdf下载App image后，串口没有反馈，如下，看“VisionSDK_UserGuide_TDA3xx”里以IPU1_0为主启动核，其他的核需要连接吗，这种方式下怎么去选择需要进行的配置和usecases呢？

此外，这两种方式下每次运行都需要Load Program一次吗，是否可以Load一次，下次可以直接进行串口的配置选择呢？

谢谢。

您好我们已经收到您的问题并升级到英文论坛，如有答复将尽快回复您。谢谢！

Kun Wang：

谢谢，参考“DS90UB962-Q1: 關於 TDA2eg Error=> i2cMdSubmitChan: i2c transfer Timeout IRQ not received – 接口论坛 – 接口 – E2E 设计支持”这个帖子，问题1中的错误有可能是I2C寄存器的配置I2C pass through是不是得配置成disabled才行呢，板子上TDA3MV那块没有用到I2C0，但是还没看到这个I2C pass through配置的接口，并且不确定是不是I2C的错误引起的RADAR Usecases不能选择配置。

Cherry Zhou：

好的收到，已帮您催促工程师的回复，感谢理解！

Kun Wang：

您好，

我们通过SDK软件程序代码定位和硬件对比发现，如下I2C的错误导致设备选择错误可能由于下面硬件原理图差异，我们自己的开发板上没有TCA6416PW和TCA6424，从而没有I2C Data数据的输入，当初可能觉得有些扩展口没有用到，但是软件编译是基于TDA3x-15X15 EVM进行的，以致在Device Power on 和Device Select出错，这个有没有办法在SDK软件上做接口的配置调整或者避开这个地方的配置呢，谢谢。

您好，

请问如下AWR1243+TDA3x的硬件连接接口是所有必须的接口吗(ProcessorSDKRadar_UserGuide.pdf)，我们自己的硬件上如下GPIO4_15没有与射频板的SPI_Host_Intr1连接，现在SDK软件中没有中断信号的输入，中断寄存器标志位可能不对，这个有没有办法配置成其他的GPIO接口作SPI interrupt？

当前通过Tera Term发现软件运行到Bsp_ar12xxRadarDeviceOn（E:\PROCESSOR_SDK_RADAR_03_08_00_00\ti_components\drivers\pdk_01_10_04_05\packages\ti\drv\vps\src\devices\radar_ar12xx\src\bspdrv_ar12xxPriv.c）后，如下timeout(0xFFFFFFFF)函数陷入无限循环，Devicepower一直没成功，radarInitCompleteFlag没有变化，这个是由 "Bsp_ar12xxAsyncEvtHandlerCb()" （ bspdrv_ar12xxPriv.c ）控制的，请问这个地方如何控制实现DeviceOn的呢？

谢谢。

UInt32 timeout = BSP_AR12XX_TIMEOUT_MAX;

gBspAr12xxObj.radarInitCompleteFlag = 0U; /* Start the first device */ retVal = rlDevicePowerOn((rlUInt8_t)gBspAr12xxObj.devIdxMap, gBspAr12xxObj.rlApp_ClientCtx);

if (retVal == BSP_SOK) {    /* Wait for the device to complete its initializaton */   while ((gBspAr12xxObj.radarInitCompleteFlag != count)   && (timeout != 0U))   {     /* Sleep for 1 ms */     BspOsal_sleep(1U);     timeout–;    } }

我们当前是把问题1中的I2C中部分代码屏蔽掉了，因为很多接口都是接HDMI、摄像头等，对于我们雷达可能没用到，也想问下此处屏蔽是否影响整个雷达Demo的运行，如果不可行，是否可通过软件的修改避开I2C的接口配置，因为当前我们硬件结构上没有TCA6416PW和TCA6424，还是说一定需要修改硬件呢？

谢谢。
