AWR6843AOP: Unable to run people counting demo on 6843AOP

Part Number: AWR6843AOP
Other Parts Discussed in Thread: SYSBIOS

Hello TI Team,

We are running 68xx_people_counting demo project from tool box mmwave_industrial_toolbox_4_1_0. We are specifically interested in this project, as we are looking for a example with 6843_AOP+DSM. In other examples, hardware accelerator is used. We need a example where DSM is used for range, heatmap calculation.

We are able to compile the MSS and DSS code. After executing the codes, we are able to get to a point where CLI gets operational but after that the code crashes. We are getting below log. We can confirm that DSS is still in running stage and mss goes in to suspended state.

Can you please let us know if there is any obvious reason for this failure. We have not made any change to the lab code and we have not sent the configuration file yet. The crash happens before that.

    Hello Rohan,

    Have you tried using a more recent version of the toolbox? ITB_4_1_0 is very old. Please also confirm if you are using the TI AOP EVM and if you are able to flash and run the prebuilt binary?

    Did you make any modifications to the code? Also what do you mean by DSM?

    Regards,

    Jackson

    Hello Jackson,

    Thanks for reply. I have mis-spelled DSS to DSM. We need a AOP example, for object/people detection, where DSS is used for data processing. In the latest version of ITB, all the example of people detection or area scanner are based on MSS and Hardware Accelerator. Thus I decided to work with ITB_4_1_0.

    The people counting demo in ITB_4_1_0 is based on SDK_3.3.0.2. As this sdk does not have support for 6843AOP, we have migrated the lab to SDK_3.5.0.4. After migration we are able to building the code. The DSS is initialising without any error, but the MSS is crashing during initialisation. 

    We are unable to run the prebuild binary, as those binaries are with sdk_3.3.0.2. As we are running the lab on 6843_AOP, the prebuild binaries are not suitable. Thus we are building new binary with sdk_3.5.0.4.

    Thanks,

    Rohan

    Can you be more specific about what you need the DSS to perform with processing? The OOB demo for AOP does only use the MSS, you are correct. But the people counting demo (compatible with AOP) performs most of the pointcloud processing on the DSS side. Only the range profile is calculated in the HWA, the rest of the processing is done with the DSP. Is there something else you are looking for?
