MMWAVEPOEEVM: MMWCAS-RF-EVM MATLAB issue

Part Number: MMWAVEPOEEVM
Other Parts Discussed in Thread: TDA2

Hi,

I hope this message finds you well. I have two questions:

  1. What is the fastest way to transfer captured data from the MMCAS-DSP-EVM to a PC?
    Is there any way to load capture data like streaming it directly to the machine via Ethernet or USB-C, rather than transferring it from the SSD card?

  2. I updated the paths in testList.txt and modified the dataFolder_calib_data path in cascade_MIMO_antennaCalib.m. However, when I run cascade_MIMO_signalProcessing.m, I get an error after a few seconds. Could you please help me with this issue?

  • Hi,

    1. What is the fastest way to transfer captured data from the MMCAS-DSP-EVM to a PC?
      Is there any way to load capture data like streaming it directly to the machine via Ethernet or USB-C, rather than transferring it from the SSD card?

    [Cesar] No, only transfer from SSD card is supported.

    2. I updated the paths in testList.txt and modified the dataFolder_calib_data path in cascade_MIMO_antennaCalib.m. However, when I run cascade_MIMO_signalProcessing.m, I get an error after a few seconds. Could you please help me with this issue?

    [Cesar] Were you able to perform the calibration? Usually the calibration is performed with a corner reflector placed at a short distance of about  3-5m

    Unfortunately the team that developed this matlab code is no longer available for support. So we can provide only limited support

    thank you

  • Hi Cesar,

    Thanks for your response.

    No, I used the default calibration file. My question is why the error appears after a few frameCountGlobal.

    I look forward to hearing from you.

  • Hi,

    Unfortunately the team that developed the matlab scripts is no longer available for support.

    Since the problem happens after a few seconds it is probably not an issue with the sensor. 

    Probably in this case the best way to debug is to check the matlab error.

    Thank you

    Cesar
