IWR1642BOOST: Configuration generated by mmWaveSensingEstimator doesn't work

Part Number: IWR1642BOOST
Other Parts Discussed in Thread: IWR1642

Hi,

I used mmWaveSensingEstimator to design configuration for IWR1642 and generated a json file. The screen shot of the estimator is shown below:

Based on the results, I generated a configuration file below:

sensorStop
flushCfg
dfeDataOutputMode 1
channelCfg 15 3 0
adcCfg 2 1
adcbufCfg -1 0 0 1 0
profileCfg 0 77 7 7.7 27.89 0 0 65.95 1 64 3126 0 0 10
chirpCfg 0 0 0 0 0 0 0 1
chirpCfg 1 1 0 0 0 0 0 2
frameCfg 0 1 128 0 200.0 1 0
guiMonitor -1 1 1 0 0 1 0
cfarCfg -1 0 0 8 4 4 0 5000
cfarCfg -1 1 0 8 4 4 0 5000
peakGrouping -1 1 1 1 1 63
multiObjBeamForming -1 1 0.5
calibDcRangeSig -1 0 -5 8 256
clutterRemoval -1 0
extendedMaxVelocity -1 0
compRangeBiasAndRxChanPhase 0.0 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 0
measureRangeBiasAndRxChanPhase 0 1.5 0.2
sensorStart

However, the DSS throws errors "Error: MMWDemoMSS mmWave Configuration failed [Error code -203685678]". 

Could you check it and give me some suggestions?

Regards,

James

    Hi James,

    Unfortunately not all configurations are supported by the standard mmWave Visualizer since they are more sophisticated than is supported by the visualizer.

    Where are you receiving this error? It appears to be an MSS error instead of a DSS error?

    Dear Akash,

    Thank you for your help. I guess I already solved the issue. I need to make some small changes to make it work, such as set the number of samples and number of chirp loops to be power of 2, and adjust other variables accordingly.

    Thanks,
    James
