Original question:

AWR2944EVM: mmwave demo visualizer data port CANNOT connect

AWR2544LOPEVM: I am trying to connect to port with demo visualizer and it keeps getting stuck trying to connect to

Part Number: AWR2544LOPEVM
Other Parts Discussed in Thread: AWR2544, UNIFLASH

Tool/software:

I have just purchased the AWR2544LOPEVM and I am trying to use the demo visualizer to start streaming data on my board. For some reason, It connect immediately to the CLI port, but never is able to connect to the data port, and it just stalls out saying "waiting for data" forever. Currently the radar is in 001 (SOP mode 4) = Functional mode, and I am using mmwave SDK 4_07_00_01, I have both ports in my device manager set to 115200 bps, and I am trying to connect to the ports in the demo visualizer with the specification that can be seen in the image. When I click "send config to mmwave device" it conects to the first port but never completes a connection to the second. I have triple checked com port and versions, what can I do?

thanks,

Rahul

    Hi Rahul,

    There is a separate demo visualizer for AWR2544. The object data is transmitted over Ethernet and not over UART. So, you won't receive any data over Data port.

    You can check the user guide at the path mentioned below for AWR2544 demo visualizer - "C:\ti\mmwave_mcuplus_sdk_04_07_00_01\mmwave_mcuplus_sdk_04_07_00_01\docs\mmWave_Demo_Visualizer_UserGuide.pdf".

    Regards,

    Samhitha

    The issue is the AWR2544LOPEVM hardware wont fully connect to the demo visualizer because the data port never connects. The sdk user guide says I need to connect to the demo visualizer to run the ethernet demo, but I cannot get the data port connected to proceed with this.

    Also, I am using a windows laptop and I see that the demo visualizer is for linux. Is there another way I can connect to the port using my windows laptop so I can run the ethernet demo?

    I have resolved my issue. For future guidance for any other having a similar problem and trying to operate the AWR2544LOPEVM and a windows computer:

    If you are using a windows computer and are having trouble using this board with the demo visualizer (my issue was data port connectivity problems), and your goal is to stream over ethernet and collect with your computer, there is a way to go from out of box to packets streaming without the demo visualizer. If you have python 3.7.4 installed you can flash the required images for demo appimage and the sbl using the uart_uniflash.py script in the sdk, and from there you can use putty or a python script that opens the CLI port connection to the board ("mmwDemo:/>" terminal) and you can send the config requirements line by line following the cli commands documentation and this notation:

    channelCfg 15 7 0 1 1

    sensorStop

    etc. etc., but to get the ethernet demo running, you have to send the commands in the "autoPhy_OSCCLK_ETH.cfg" config file, but the only way to get the packets on a windows computer is to port forward from windows port to a wsl port, and then within wsl you need to build and run a udp listener to collect the packets, because the AWR demo is built for a linux host system. Hope this helps.
