IWR1443BOOST: how do I use the csi_stream to see raw ADC data?

Colleen Josephson1

Part Number: IWR1443BOOST

In the mmWave SDK v1.2 the release notes say, "CSI stream (IWR14xx) application within mmWave SDK that showcases how to stream ADC data over CSI-2 interface".

I have successfully loaded and run this unit test using CCS, but I don't see any ADC data. Where should I see it? Are additional steps needed to see/capture the ADC data? If so, what are they?

This is what I see in my console after loading and running xwr14xx_csi_stream_mss.xer4f:

Before running the unit test, I flashed the device using xwr12xx_xwr14xx_radarss.bin for the RadarSS image and xwr14xx_ccsdebug_mss.bin for the MSS image.

Hi Colleen,

I've sent your inquiry to our expert. In the meantime, did you hook up the IWR14xx EVM with a receiver through CSI2 interface or use it by itself?

Thanks and Regards,

Michelle

Hi Michelle,

I have connected the IWR1443BOOST to a mmWave-DevPack using the samtec connector, and both the devpack and the boost are connected via USB to my computer. Do I need a separate CSI2 interface to receive CSI2 data on my computer?

Hi Colleen,

You can check the ADC output data in L3 (gDataCube 0x51020000) from the memory browser. But to verify CSI2 streaming, you will need a receiver which support CSI2 interface to connect to Boost/DevPack. I don't think your PC has CSI2 interface.

Michelle
