IWR6843ISK: Visualizer error during IVM6843ISK demo test

IWR6843: I get errors when trying to run demo wave visualizer with IWR6843ISK

I can't find a 3.2 version of the demo program or a clear way to compile my own as a CCS project, but I did find a bin file for 3.1 that I can flash to my board and it seems to connect to demo wave.  But it seems no matter what config parameters I enter, I always get errors that keep it from being downloaded.   Here is a screen capture of as far as I got:

    I made copies of the 3.2.0.4 directory I had been using, used your link to install a new one and beyondCompare told me they are the same.

    You tried flashing below binary file on IWR6843ISK:

    ~\mmwave_sdk_03_02_00_04\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo.bin

    You are still getting the errors?

    Yes, I directed UniFlash to program that file.  Lately,   I can't get UniFlash to program it - I get an error "Image loading failed: Not able to connect to serial port. Recheck COM port selected and/or permissions."  I also power cycle between attempts and made sure I have no demo apps running in my browser.   I've tried disabling and reenabling the serial port.   I had that problem most of the early part of this week, for some reason, that problem went away for a while tomorrow afternoon.  I just tried to connect terraterm to the port but it said it was unavailable.  I tried bypassing my USB hub and the port still isn't available.  I have the jumpers for SOP 2 and 0 in.  My device manager calls my port XDS110 Class ApplicationUser UART (Com 82).  My port 81 - the Data port isn't available either.

    I did find that my UniFlash failure was fixed by restarting my PC.  Now I use teraterm first - if that can't connect to the data and cfg port, I need to restart the PC.  I did finally get that file programmed but now am back to a failure of Data Visualizer eternally just saying "Connecting to 2 of 2 targets".   I've had that problem most of this week, but there was one time where it worked, but afterwards the data wouldn't load.   I have a picture of what it says now:

    Hi Eric,

    After sending the config the data port should connect and you should start seeing the data.

    Thanks

    No, I've never seen data back yet.  Yesterday, it would eternally just say it was trying to connect with 2.   I did find a sequence that lets me get a little farther today:

    • start up the PC fresh with the eval board powered down and disconnected.
    • start up data visualizer but turn off the connection attempt
    • power up the eval board to let it start up and load its USB stack
    • plug in the USB connection
    • click the lower left icon to let the demo program try to connect.

    This sequence at least got it a little farther along. Below is an image of where it then eternally just waits for data.    If you could send me the embedded source code file that manages the dev board side USB connection, I could maybe make some free fixes for you folks.  I've seen a lot of times where higher level embedded code doesn't take enough time during transactions to allow a connection to really work.  That kind of problem can be difficult to track down for different PC's connecting.
