IWR1642BOOST: Ppl count demo CLI hangs

Part Number: IWR1642BOOST

Hi,

we have been using the mmwave_industrial_toolbox_3_6_2 for testing the device. From there, we have used the precompiled binaries for lab 11, the people counting demo. However, now we noticed that after issuing a sensorStop command, the CLI hangs up or gives Error -1 error message on certain configuration commands.

The usual culprit is adcbufCfg command which hangs up the device or produces Error -1 message. Other command which may produce Error -1 message is adcCfg.

If the device has just been rebooted, the same configuration goes through without any problems, so it seems to be related to the state of the device after sensorStop command. Also, issuing the same configuration without sensorStop, just flushCfg, command does not give any indication of any errors, but of course not all parameters are updated.

Best regards,

Marko Leppänen

  • Hi Marko,

    Lab0011 does not support sensorStop.  To enable the signal chain on this device, we can only configure once due to memory requirements. Data structures used for initialization/control are overwritten for data processing during the configuration process, meaning we must restart the device to get back to a state where configuration is possible.
