Hi,

I used the mmwave demo to integrate the cascading of 2xAWR2243, I used following configuration and it fails when configuring the slave radar.

char* radarCmdString[MAX_RADAR_CMD] =
{
"sensorStop\n\r",
"flushCfg\n\r",
"dfeDataOutputMode 1\n\r",
"channelCfg 15 7 0\n\r",

"lowPower 0 1\n\r",
"dataPathClkCfg 1 1\n\r",
"profileCfg 0 77 267 7 57.14 0 0 70 1 256 5209 0 0 30\n\r",

"compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0\n\r",

"extendedMaxVelocity -1 0\n\r",
"calibData 0 0 0\n\r",
"sensorStart\n\r"
};

Could you please give me a correct configuration which works with the 2xAWR2243 ?

Thanks.

    Hi,

    Are you using any SW from Texas Instruments?

    Are you using a custom EVM?

    Thank you

    Hi Cesar,

    I am using the ti mmw demo provided within mcu plus sdk for am273x with our board based on TIDA-020047 reference design.

    I am using it as a starting point for my application , I am using the CLI BYPASS MODE to use a static configuration and trying to integrate the cascading of 2xawr2243 radars.

    The application fails when configuring the slave radar.

    could you help us with the correct configuration and the needed modifications in mss and des to support the cascading.

    Thanks.

    Hi Mohammed,

    Can you please give more details on the changes you have made and the fail case behavior that you are observing? Is there an mmwavelink error code generated or some other behavior when trying to configure the slave?

    Regards,

    Hi Gowda,

    I Integrated the configuration of AWR2243 from the cascade test into mmwave demo in mss code source and the configuration is done without error for the two radars.

    But I still need to update the dss part to support reading ADC samples from the slave radar and integrate them in the processing chain to check if the cascading is working correctly.

    Could you share with me the dss code source which should be update in mmwave demo to get the cloud points from 2*AWR2243, because the mmwave demo support only one AWR2243 radar ?

    Thanks.

    Hi Mohamed,

    We currently do not share any SW with respect to the any radar processing as this is only a TI reference design. You would have to understand the demo and make your own changes for the time being.
