IWR6843AOP: Soft sensor restart

pikopro developer

Part Number: IWR6843AOP

Tool/software:

Hi,

I’m currently working on a fall detection application using the following reference project:
C:\ti\radar_toolbox_3_10_00_05\source\ti\examples\Industrial_and_Personal_Electronics\People_Tracking\Overhead_3D_People_Tracking.

One of our key requirements is to stop the sensor while it's actively sensing, update the configuration, and then restart it — all without powering down the board. However, after doing this, we no longer receive any TLV packets.

Additionally, we need the ability to remotely restart the sensor without a full power cycle. To achieve this, we attempted a soft reset of the MSS core using the following steps. While the MSS core does restart, TLV packets still do not appear. The system works as expected after power reset.

Note: The .cfg file is hardcoded into the firmware

Soft reset sequence:

Do you have any idea about this? that is the most important one of our requirement.

Thanks

You could do this with a GPIO instead of a CLI. When the GPIO goes high, you can run the code in the CLI shown at the link.

Best,

Hi Nathan Block ,

Couldn't able to find it out. Kindly guide. Our requirement is to update the config file while the sensor is already started and detecting objects.

Hi,

Are you actually changing the chirping parameters? Or just the detection parameters? If you don't change the chirping parameters then no update is needed.

Best,

Nate
