IWR6843ISK:IWR6843ISK

Part Number: IWR6843ISK

I am using IWR6843ISK board and the 68xx_mmwave_sdk_dsp of out_of_box_demo as project code.
I have three question.

First,

I know that DPM has three mode. (DPM_Domain_DISTRIBUTED, DPM_Domain_LOCALIZED, DPM_Domain_REMOTE)Currently,

The 68xx_mmwave_sdk_dsp of out_of_box_demo is DPM_Domain_DISTRIBUTED.

I want to use DPM_Domain_REMOTE, but there is no sample project.

I installed mmwave_industrial_toolbox_4_5_1 and mmwave_sdk_03_05_00_04.

I tried to find the sample project of DPM_Domain_REMOTE mode. But I didn’t find.

How can I get the sample project of DPM_Domain_REMOTE mode?

Otherwise, How must I modify at current project code?

Second,
currently, I am using the RangFFT of HWA and the LVDS at the same time.

Is it possible using only LVDS without RangeFFT operation of HWA?

As another question, Is it possible using LVDS with RangeFFT operation of DSP?

Third,
I want to modify C:\ti\mmwave_sdk_03_05_00_04\packages\ti\datapath\dpu\rangeproc\src\rangeprochwa.c,

But project is including as library file (librangeproc_hwa_xwr68xx.aer4f).

So I can not modify that file. How can I do?

thank you.

    Hello,

    You can look at the xwr18xx mmw demo which configures DPM in remote domain mode:

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\demo\xwr18xx\mmw\

    Additionally. you can also look at DPM unit tests in the following directory 

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\control\dpm\test\remote

    Regarding modifying and re-building the rangeDPU code (or any other DPU), please refer to the following training, slide-43

    Thanks

    Hi Nitin Sakhuja

    thank for answering above question.

    please answer for above second question.


    and I have another question for above third question.
    I understood that I should remove –O3 option of R4F_CFLAGS & C674_CFLAGS at the mmwave_sdk.mak of C:\ti\mmwave_sdk_03_05_00_04\packages\ti\common.for rebuilding of pre-compiled libs.

    so, I removed –O3 option at the mmwave_sdk.mak of C:\ti\mmwave_sdk_03_05_00_04\packages\ti\common.
    How can I rebuild with what tool?
    please explain for rebuilding method in detail.

    thank you.

    Hi Lim,

    This is described in the SDK user guide in the following section.

    Basically, to re-build any SDK components (drivers, DPUs, pre-compiled libs, or even the demos using the SDK makefile), you need to follow the below steps:

    1. Open a command prompt and cd to C:\ti\mmwave_sdk_03_05_00_04\packages\scripts\windows

    2. Run setenv.bat in the command prompt to setup the build environment

    3. cd to the desired component directory IN THE SAME command prompt (where the component top level makefile resides). 

    4. run gmake clean all

    Thanks
