AWR2944EVM: out of the box 2944 demo TDM not working with example profile config

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944, UNIFLASH

Tool/software:

Dear Expert,

I am attempting to set up the out-of-the-box 2944 demo in TDM mode.

I have defined the MMWDEMO_TDM symbol in the environment and built the project accordingly. Then, I sent the TDM configuration files from the following path to the mmWave Demo Visualizer:

C:\ti\mmwave_mcuplus_sdk_04_04_01_02\mmwave_mcuplus_sdk_04_04_01_02\ti\demo\awr294x\mmw\profiles\tdm_awr2944

I have tested all the provided files, but I keep encountering the warning:
"Debug: Init Calibration Status = 0xffe"
Additionally, there is no serial traffic (I also verified this using PuTTY).

Could you please advise on what might be going wrong?

Best regards,
Francesco

    Hello,

    For reference that is not a warning, just a status update. Also, I want to verify two things, where did you get the projectspec files you are developing on (so I can recreate the environment as closely as possible) and did you check the data port (not the application UART port) for the serial traffic?

    Best,

    Gabriel

    Please highlight what you changed in the project as well to build as TDM demo.

    Dear Gabriel, thank you for your very fast response.

    I downloaded the example out_of_box_example_2994 from the Online Resource Explorer of CCS 12.4.0 (both mss and dss projects)

    Then I changed on mss project properties, under the Predefined Symbols the MMWDEMO_DDM variable to MMWDEMO_TDM.

    I then built the project and run the application loading the config file as I previously described. (I tried both debug from CCS and standalone with uniflash).

    I can read from application port (e.g if I send "version" I can read that ProcChain: TDM)  while I don't see any data on the data port (after the sensorStart command).

    For the projectspec request, could you help me to understand where is located?

    Thank you again,

    Francesco

    Hello,

    Yes, it does appear there is a problem with the TDM demo. For context imported projectspecs from this location in the radar toolbox and I added defines in order to run the TDM demo (it is originally a DDM demo).

    C:\ti\radar_toolbox_3_00_00_05\source\ti\examples\Out_Of_Box_Demo\src\awr294x

    So, I would like to ask further insight on your application and offer two options.

    1) If you just need the TDM demo running then you can flash the app image at the following location and run the demo with a profile from the same folder you used. (I verified it is working)

    "C:\ti\mmwave_mcuplus_sdk_04_07_00_01\mmwave_mcuplus_sdk_04_07_00_01\ti\demo\awr294x\mmw\awr2944_mmw_demoTDM.appimage"

    2) If you want to develop and don't specifically need the TDM demo then I recommend using the projectspec at the location in the radar toolbox I said at first. It is for the DDM demo which is more widely supported throughout the radar devices. I tested it and verified it is working correctly. If you have any issues building refer to our last E2E
