RTOS/AWR1642BOOST: DSS Exception when trying to configure 0 transmitters

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: MMWAVE-SDK, MMWAVE-STUDIO, AWR1642

Tool/software: TI-RTOS

I am trying to write a configuration file that does not activate the transmitters. I've inserted the code to this thread. Every time I try to run it, the console produces an error message stating:

mmwDemo:/>sensorStart
Debug: Init Calibration Status = 0x7fe

DSS Exception: dss/dss_main.c, line 2246.

Even though every command in the file compiled just fine. The SDK version is 1.2. Would there be any reason why this version of SDK would not support 0 transmitters? How else am I supposed to get a reading of the noise floor?

  • Hi Samuel,
    mmWave-SDK is not meant for this kind of test, it has checks for each CLI parameters. So, it's ASSERTing for chirpConfig parameter where TX selection is not given.

    For this type of test I would recommend to use mmWave-Studio with DCA1000/TSW1400 where disable Tx selection in ChannelConfig and chirpConfig commands and capture the raw data and process at mmWave-Studio.
    Else modify the mmw demo application to achieve your goal.

  • So just to clarify, you suggest purchasing the DCA1000 so that I can read ADC data and do the all of the signal processing on my computer?
  • Yes, for long-term and doing much more performance test with AWR1642, DCA1000 will be a good option where you can fetch out raw data from the device over LVDS and store at PC, further do the processing as required.

    For the above-mentioned usercase where you need to check noise floor with Tx off, you can either modify the mmw demo application to obtain the required output.
