IWR6843: Area scanner, long range people detection error

Part Number: IWR6843

We made the board using the IWR6843 chip on the AWR1843boost.

The Area Scanner example(mmwave_industrial_toolbox_4_0_0\labs\area_scanner\68xx_area_scanner) does not work.

The error message appears as shown in the picture.

The port and switch are correct.

Running the 'Long range people detection' example results in an error as shown in the figure below.

The output argument strPorts was not charged during call to setupget_com_ports. Other arguments may not have a value.

How do I fix the errors in the two examples?

Other examples such as 'vital signs' work well.

    Hello,

    As of Industrial Toolbox 4.0.0. all IWR6843 ISK labs including Area Scanner & Long Range People (except Vital Signs) run on ES2.0 silicon. The demo will not run on ES1.0.

    You can see a summary table of the supported devices here: 

    Reference this guide to confirm that your device is ES1.0

    ES2.0 IWR6843 devices are now shipping and can be ordered from the TI Store.

  • Q1. What is the difference between ES1.0 and ES2.0?

    Q2. Why aren't they compatible with each other?

    Q3. Is there any way to use the ES2.0 example in ES1.0?

    1)      The differences between the silicon revisions can be determined from the IWR6843 Device Errata. The updated document including ES2.0 will be available by next week

    2)      The latest version of the mmWave SDK 3.3.x.x only supports the latest IWR6843 device (ES2.0). Labs are released for support with the current SDK and device platform. Compatibility with previous ES1.0 devices is not maintained in the SDK nor in future lab updates for the mmWave Industrial Toolbox.

    3)      To use the latest labs users are encouraged to migrate to ES2.0 devices. However, users may refer to the release notes in the mmWave SDK and the Migration Guide to implement backwards support for ES1.0. Please note further support for migrating the labs back to ES1.0 will not be provided.
