AWR2243: CQ Question Regarding 2243

Gary Lu

Part Number: AWR2243

Hello，

We have configured the CQ1 register of AWR2243 as follows

Then we observed the CQ1 data output as follows:

The problem is as follows
1. Why did I set 16 slices, but only 8 valid data outputs were missing? (Note: The first two zeros and 16 are information for 0 and N)
2. How can I calculate the signal power back from the above data? My CQ configuration is 16bit, and the entire data format configuration is as follows:

Regards，

    Hi Gary,

    Please provide the below information below.

    1) What SDK version you are using.

    2) Which board are you using. What is your test setup. 

    3) Are you suing a custom code or any of the TI examples.

    4) Can you share the memory dump (1 KB) form the device form this address 0xA5010000

    Thanks,

    Pradipta.

    Hello，

    1) The SDK version is V2.2.2.1;

    2) AWR2243, the hardware is 1.1, we have clearly stated the settings of the CQ1 register and the datapath above;

    3) I don't understand what you mean, but about the setting of CQ1, we complete it by calling two interface functions:

    //Set CQ1 register

    int MMWL_setRxSigImgMonConfig(unsigned char deviceMap)
    {
    int32_t retVal; /* initialization return value */
    rlSigImgMonConf_t RxSigImgMonCfg = { 0 }; /* Initialize signal and image band energy */

    RxSigImgMonCfg.profileIndx = 0;
    RxSigImgMonCfg.numSlices = 16;
    RxSigImgMonCfg.timeSliceNumSamples = 8;

    retVal = rlRfRxSigImgMonConfig(deviceMap, &RxSigImgMonCfg);
    return retVal;
    }

    rlRfAnaMonConfig() This interface function enables the corresponding bit and turns on RX_SIG_IMG_BAND_MONITOR (CQ1).

    4) What is the address 0xA5010000? Our AWR2243 is connected to the FPGA through lvds, so we don’t know what address you mentioned

    Regards，

    Gary

    Hi,

    For AWR2243, can you please move to using the latest SDK and DFP version. Meanwhile i will check this on the bench and let you know of my observations.

    Thanks,

    Pradipta.
