IWR1642BOOST: No figure can be viewed in the mmwave demo visualizer

IWR1642BOOST: No figure can be viewed in the mmwave demo visualizer

Part Number: IWR1642BOOST

When using the IWR1642boost and the mmWave Demo Visualizer, everything seems to go fine but I can't see any data on the PLOTS tab.

Below are screenshots of my setup and steps. Ports:

Configuration in mmWave Demo Visualizer (downloaded app, not browser):

Message after CONFIGURE:

After "SEND CONFIG" - It says Connected, there are acknowledges on the console and sensor is started:

But there is no data at all:

    Hi Juan,

    After "sensorStart", it should have a "Done".

    Could you please check the SDK version and the GUI version? it should match.

    Also, you can try both SDK1.1 and SDK1.2. The bin file is in C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr16xx\mmw\xwr16xx_mmw_demo.bin

    If you have any further questions, please let me know. Thanks.

    Regards,

    Wesley

    i finally managed to upgrade the board to SDK 1.2 but keeps doing the same, no done after the 'start' command and nothing is displayed.

    Hi Juan,

    Can you please check the hardware connection on the EVM? Pin: UART_TX, UART_RX, MSS_LOGGER
    You can refer this link: e2e.ti.com/.../611295
    Thanks.

    Regards,

    Resistor R136 in AR_MSS_LOGGER is not assembled, should it be?

    (Edit) Some colleague just told me he was getting data with that same board previously.

    Hi Juan,
    Yes, R136 should be mounted. Could you please try to probe the MSS_LOGGER using oscilloscope?
    Thanks.

    Sorry, the resistor was there (so small...). I check with a scope on R136, it's all the time at 3V3 when connected.

    I had R166 and R169 shorted to see the AR_RS232RX and AR_RS232TX signals in J6 and yes, I can see communication (both lines) when clicking on SEND CONFIG TO MM DEVICE, but after that there is no more activity

    when upgrading the board I just flashed xwr16xx_mmw_demo.bin, is that all is needed?

    Hi Juan,

    Yes, you can flashed this bin file. C:\ti\mmwave_sdk_01_02_00_05\packages\ti\demo\xwr16xx\mmw\xwr16xx_mmw_demo.bin
    Here's the setup guide, and you can try again. dev.ti.com/.../
    If it doesn't work, can you please use your colleague's PC to try it?

    Thanks.

    I tried on a separate computer allegedly without so many network restrictions, just in case.

    I followed these directions:  https://usermanual.wiki/Pdf/TImmWaveROSDriverSetupGuide.1805530920.pdf  

    But the result was about the same, it fails after no answer to the startSensor command:

  what():  SerialException device reports readiness to read but returned no data (device disconnected?) failed.

    So maybe the board is faulty, but why does it communicate?

    Any ideas?

    Ok, sorted... it was my power supply with the current limit just above the consumption before starting the RF
