IWR6843AOPEVM: People Counting 3D demo

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST, IWR6843AOP, UNIFLASH

Hi everyone,

I'm new to mmWave devices, I have recently acquired an IWR6843AOP EVM and a MMWAVEICBOOST. I have succesfully tested the Out-of-box demo on it and now I'd like to test, if possible, the 3D People Counting demo from the latest ToolBox (4.1.0) although the docs do not mention compatibility with the AOP (they do mention compatibility with IWR6843-ISK and ODS). I tried flashing the board with the "3D_people_count_68xx_demo.bin" and sending the ODS chirp config file (as from what I've understood it has a similar antenna pattern to the AOP) but after the configs are sent nothing happens. I remarked that the sensor replies to each config command with ' '  in the Python console (I'm not sure if it is relevant). It is possible to acheive what I'm trying to? If not, do you expect to release soon a 3D People Counting lab for the IWR6843AOP EVM? If it's possible, could you please guide me on what am I doing wrong?

I'd also like to express that I experienced some difficulties when trying to flash the board using UNIFLASH, the desktop app seems not to detect the mmwaveicboost device while the online version does. Does it seem normal to you?

Thank you for your time,

Best regards,

Pedro

    Hi Pedro,

    I've asked an expert to look into this and we should have an answer for you sometime next week.

    Hi Pedro,

    Unfortunately, the 3D People Counting demo will not natively run on the AOP device at this time. AOP is an ES1.0 device, which requires older firmware than the ES2.0 devices the demo is built for. However, you can still compile for ES1.0 devices. You will have to undo the migration steps in this guide. Essentially:

    1. Compile with SDK 3.2.0.6
    2. Fix the errors. Errors will appear indicating that a specific struct member does not exist - simply remove the line that sets a value to this.

    Once you are able to compile for ES1.0, post here if you need help with the configuration.

    Regards,

    Justin
