DCA1000EVM: 采集ADC原始数据,文件大小只有8KB

Part Number: DCA1000EVM
Other Parts Discussed in Thread: TIDA-020047,

你好,

硬件平台:TIDA-020047

我使用DCA1000,采集原始数据,

我使用的说明步骤如下:

DCA1000EVM_CLI_Control.exe fpga AM273X_Capture.json


DCA1000EVM_CLI_Control.exe start_record AM273X_Capture.json

执行完之后,采集到的原始数据大小只有8KB,这8KB 数据看起来就是obj->staticCfg.ADCBufData.dataSize/2的大小,也就是说,看起来是只发送了一次数据,请问这是什么原因?

 if (MmwDemo_LVDSStreamSwConfig((uint32_t) gConfigCsirx0ContextConfig[0].pingPongConfig.pingAddress,
                                     (uint32_t) gConfigCsirx1ContextConfig[0].pingPongConfig.pingAddress,
                                     (uint32_t) obj->staticCfg.ADCBufData.dataSize/2) < 0)
        {
            test_print("Failed LVDS stream SW configuration\n");
            DebugP_assert(0);
        }
        
        
    
    staticCfg->ADCBufData.dataSize = RFparserOutParams.numRxAntennas * RFparserOutParams.numAdcSamples * sizeof(cmplx16ImRe_t);
