AM2732: EDMA configs for cascading radar + AWR2243

Amine LTAIEF
Intellectual 545 points
Part Number: AM2732
Other Parts Discussed in Thread: AWR2243,

Hello

could you please help for these points :

1. Does the mcu_plus_sdk_am273x_08_05_00_24 support the cascading mode ?

2.Does the transfert between ADC row datas and HWA is done throught EDMA or directely.

3. in DPC_ObjDet_rangeConfig() I notice that you support only 3Tx and 4Tx (AWR2943), how is possible to configure it for 6Tx (case of cascading).

Regards

Amine

    For radar application support on the AM273x, please see the mmWave MCU PLUS SDK package: https://www.ti.com/tool/MMWAVE-MCUPLUS-SDK. The standard MCU PLUS SDK do not have radar application examples. Note: this is a bare-metal and TI-RTOS based SDK and not ported to FreeRTOS like our latest MCU PLUS SDK packages.

    In what context are you referring? Please refer to the HWA examples in the linked MMWAVE SDK.

    Is this something from the mmWave SDK or somewhere else? There should be a 2x AWR2243 use-case example for 6TX, 8RX in there. Let me know if you cannot find that. 

    Thank you,

    Hi 

    Thank you please guide me for this point. An additional question please, which example or demo advice to start with to develop my application based on 2 cascading AWR2243 + AM2732. I'am asking about row data processing part.

    Regards

    Amine

    Hi Amine, 

    1. Currently, it looks like the AM273x mmWave or MCU SDK do not have cascade radar support. 

    2. Check out the hardware accelerator and EDMA examples in the MCU SDK: 

    • C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_am273x_08_05_00_24\examples\drivers\edma
    • C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mcu_plus_sdk_am273x_08_05_00_24\examples\drivers\hwa 

    I am still not sure what SDK/example DPC_ObjDet_rangeConfig() refers to. Can you please tell me what that is referencing?
