IWR6843ISK-ODS: People Counting ES2.0

Thanks for your reply.

We have a need for a ceiling mounted application. Is there any way to recompile the Area Scanner Project or the 3D people counting in order to support a ceiling mounted IWR6843?

What code should be changed in order to acheive this?

Thanks

Also, I wasn't able to sucessfully run the application compiled for IWR6843 ES 2.0.

When building ods_pplcount_dss_68xx I get the following warnings, although it finishes building:

If I try to run the GUI it outputs an error:

Hello,

It appears that you have not followed some/all of the instructions provided in the migration guide for porting the application from IWR1642 to IWR6843. This is shown by your build log which still shows the 16xx libraries being linked .

Thank you for the fast reply.

Well I though the previous project didn't link IWR16xx libs, so I followed the 6843 ES 1.0 to 2.0 Migration Guide.

After following the guide for porting IWR1642 application code to IWR6843 ES2.0 I am still getting some errors.

I tried to follow all applicable steps in the guide, but something must still be wrongly configured.

Is TI planning to release an updated vesion of this lab?

And from the MSS project there is a include that path that is incorrect:

Invalid project path: Include path not found (C:\ti\mmwave_industrial_toolbox_4_1_0\radarDemo).	ods_pplcount_mss_68xx		pathentry	Path Entry Problem

Which should be related to the error in DSS, am I correct?

Thanks in advance

It seems there is some confusion. To port the 6843 ODS people counting lab from ES1.0 to ES2.0 silicon, you need to follow the instructions in the IWR6843 ES1.0 to ES2.0 migration section as I indicated originally. However, I saw the xWR16xx libs being linked in your build log, so thought you were working with IWR1642. Something doesn't seem right in your build environment or projects.

Could you please create a new CCS workspace, start with a fresh install of mmWave Industrial Toolbox 4.1.0 and follow the migration steps to move from 6843 ES1.0 to 6843 ES2.0 and provide your build log?

Regards

Hi,

I have reinstalled TI's Industrial Toolbok 4.0.1,started a new Workspace on another folder and re-imported the ods_pplcount_dss_68xx and ods_pplcount_,mss_68xx projects.

First of all, when importing two DSS projects showup, I tested with both without noticing any difference.

As said in the previous comment, these projects are effectively linking iwr16xx libraries, which is strange.

First I changed the versions of mmWaveSDK and SYS/BYOS to versions 3.0.3.03 and 6.73.1.01, respectively.

Even if I proceed to change the libraries to point to xwr68xx libs,it still outputs:

Most of the other steps in the guide do not seem to apply.

Can you confirm this or replicate the error,I think the DSS project is still linking to IWR1642 devices.

Thanks

Any updates?

Thanks

Hello,

You are correct, the existing 68xx overhead people counting projects seem to be linking xwr16xx libraries which is incorrect and needs to be fixed. However, it still works on 6843 ES1.0 as the two devices are compatible on the ARM and DSP side.

However, for ES2.0, you must link the xwr68xx libs to be compatible with the ES2.0 device.

Thanks for bringing this to our attention, we will correct this in a future update.

Please list the changes, referring to the corresponding items from the 6843 ES1.0 to ES2.0 migration guide. List all changes, the ones you've made as well as the ones you feel are not applicable.

Thanks

However, for ES2.0, you must link the xwr68xx libs to be compatible with the ES2.0 device.

Sorry, but can you describe how to properly do it?

Thanks
