[AWR1843BOOST] The MRR lab of AWR1843 don't work

Other Parts Discussed in Thread: AWR1843

Hello,

I change the value of  MAX_NUM_DET_PER_RANGE_GATE of  MRR lab of AWR1843 to 10.

I execute the MRR GUI , then the GUI have no object.

And i use the debug mode of CCS to debug, and i find the error  at "MmwDemo_dssAssert(dataPathObj->chirpCount != 0)" of dss_main.c

How can i solve this problem?

In the other hand, there is a bug at line 61 of "dss_mrr_linker.cmd" .

thank you.

    Hi,

    If I understand correctly, the MRR lab works out of the box, but it does not work after you modify the value of MAX_NUM_DET_PER_RANGE_GATE.

    The MRR lab is a highly optimized implementation of a specific processing chain. The optimization is constraint by memory requirements and processing cycles.

    When increasing the "MAX_NUM_DET_PER_RANGE_GATE", the memory requirements and processing requirements change and are no longer compatible with the rest of the configuration.

    You would need to analyze the code and understand the impact of increasing "MAX_NUM_DET_PER_RANGE_GATE"

    We can help with that.

    What is the reason you would like to increase "MAX_NUM_DET_PER_RANGE_GATE"?

    Thank you

    Hello, Cesar

    The number of object's point is too few, so we can't  observe the shape of a person's body.

    Then, we want to increase "MAX_NUM_DET_PER_RANGE_GATE".

    Thanks you

    Hi,

    Can you please provide more details about the application you are trying to achieve with this demo.



    The MAX_NUM_DET_PER_RANGE_GATE is used for performing maximum velocity enhancement which is useful for mid range velocity measurement.

    if (obj->processingPath == MAX_VEL_ENH_PROCESSING)


    The MRR demo supports 2 modes: MRR and USRR.

    It seems to me that you would be more interested in USRR mode since USRR mode uses MIMO for better angular resolution and is configured for a range up to 20m.

    Thank you
