IWR1443: Wrong measurements obtained when using MSP432P401R

Part Number: IWR1443
Other Parts Discussed in Thread: TIDEP-0091,

Hi,

We are trying to use the IWR1443 BOOST EVM to make low power measurements using MSP432P401R. But, we are getting wrong measurements zero or negative values or even extremely large negative values. We are using mmWave SDK 1.02.00.05 version and msp SDK 2.10.00.14 and CCS version 7.4.0.00015 to build the level sensing demo project. We also tried to use the prebuilt binaries and they do not work either.

When we enable the report time measurement in the code, we always have Measurement Timeout(Boot) error displayed.

Let us know if there are some additional changes to be made in the code or something else to be done.

Thanks and Regards,

Harsha.

Hello Harsha,

You are using TIDEP-0091 correct? Would you be able to post a screenshot of your serial output? We need more information in order to help you.

Cheers,
Akash

Hello again Harsha,

Can you confirm you've made the appropriate hardware modifications on your IWR1443BOOST? These are on pages 15 and 16 of the getting started guide (level_sensing_gsg.pdf).

Cheers,
Akash
