AWR2944EVM: Nothing happens when attempting to flash python code

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944

Tool/software:

I am following the mmwave_mcuplus_sdk_user_guide.pdf. On pages 40 and 41. once I get to the place to flash the python code nothing happens and the command line reopens. 

I believe the issue may be when I am changing the default.cfg path. although I open the txt file and change it to this 

I can still find the default file in the normal path. What should I try to complete flashing the radar.

    HI,

    Can you observe the COM XDS UART port in Device Manager?  Which path is default.cfg in?    You should see some progress information.

    regards,

    Ali

    Hi, I have managed to get passed this point. I am now attempting to flash the awr2944_mmw_demoTDM.appimage. the terminal claims that the flash was successful. So I then power cycle and switch to the SOP to 100 and open puTTy to check the see if the I am reading any data and nothing appears. I am reading COM13 which is the XDS110 Class Auxiliary Data port at a baud rate of 921600. Have I made a mistake or what are things I can do to attempt to read the data.

    HI,

    Please see terminal settings attached that work.  Also, the port to use is the XDS UART port.  Let me know if you still face issues.

    regards,

    With these being my ports

     

    I switched to COM 14 as you suggested and input the settings you have shown 

     

    The issue remains.

    When you setup the COM ports in putty, do you see a prompt on the screen?  If you hit enter, does the prompt refresh and give you a new line?  This is sign of a good connection. 

    When you 'boot' using. SOP '001' (that is SOP0=1, SOP1=0, SOP2=0) you should see some feedback in terminal upon boot - but that depends on the application image. 

    regards,

    Ali

    Thank you, I can now see what I am sending through the CLI port. However, I am having an issue reading the data from the data port. Is the baud rate the same as the CLI port or is it 921600?

     By CLI you mean the UART? Can you share what you see from 'CLI' port. 

    Are you trying to run the visualizer in the OoO Demo?  Is that when you don't see data?
