Linux/AWR1443BOOST: Restart sensor without power cycling

PSA
Prodigy 30 points
Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443

Tool/software: Linux

Hi E2E Community,

Is it possible to sensorStop the AWR1443BOOST, flush/load an old/new configuration, and sensorStart the the AWR1443BOOST without a power cycle?

I am currently using the ttyACM0/1 ports to access the module; I can load the configuration and see data outputted on the first pass, but after I sensorStop, the module refuses to sensorStart on the second pass. A power cycle seems to be needed before the module can run again.

Is power cycling a requirement for loading a new configuration using the ttyACM0/1 ports? 

Thank you.

    PSA,

    Yes, it is possible to implement the following scenario:

    - Start the sensor with configuration #1
    - Let the sensor run for a period of time
    - Stop the sensor
    - Restart the sensor with configuration #2
    - Let the sensor run for a period of time
    - Stop the sensor

    Power cycling is not a requirement for loading a new configuration.

    I would recommend taking a look at the configuration files that are included in the SDK 1.2 release that supports AWR1443. You can find this directory here: C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr14xx\mmw\profiles

    All of these configuration files being by issuing the following two commands:
    sensorStop
    flushCfg

    This will stop the sensor and flush out any existing configuration before loading any new configurations.

    Please reply if you have any additional questions or if this response requires any clarification.

    Regards,
    Kyle
