IWR6843ISK: Reset

Hardware Engineer

Part Number: IWR6843ISK
Other Parts Discussed in Thread: IWR6843

I have IWR6843ISK. I would like to know if there is a way to reset the radar similar to the function of the hardware reset button on the board? Ideally, it would be done through sending a reset pulse to a pin on the board.

Hello User,

You could refer to the Technical reference manual (TRM) and schematics for details on the reset modes of the device.

Here is the link :

Looks like NRESET or WARM_RESET (Table 5.5 on page 298 in https://www.ti.com/lit/ug/swru520e/swru520e.pdf) will reset the radar. Does either of these pins have a header that I can access on IWR6843ISK PCB?

Also, Table 5.5 lists "16xx/14xx" under the "Devices" column. Is Table 5.5 applicable to IWR6843?

You can refer to the board schematics and look for these pins.

Yes, it is applicable to IWR6843 as well. I think I attached a wrong link by mistake earlier. We have a similar technical reference manual for IWR devices as well, here is the link : https://www.ti.com/lit/ug/swru522e/swru522e.pdf

Hope this clarifies your concerns.

Thank you. Looks like NRESET is connected to the 60-pin connector.
