AWR2944PEVM: Connection Error with DDM Demo AWR2944PEVM

Part Number: AWR2944PEVM

Tool/software:

Hey,

We're using a AWR2944PEVM and all of the compilation works well with the DDM demo, but once we've flashed it to the AWR and tried to connect to the demo viszualizer we get no connection. But the TDM demo connects without any problems. We're using mmwave_mcuplus_sdk_04_07_01_04, we've tried to downgrade the sdk but then we just get compilation errors.

    Hi Emil,

    Can you use a terminal emulator like Tera Term and check if you see the below logs when connected to Application/User UART? Ensure that the COM port is not utilized by any other application. For example, if you are connected to Tera Term, you cannot establish connection in the visualizer.

    Hey,

    When using tera term to connect to the AWR2944PEVM flashed with the mmw_ddm enet demo, we see the output like in your screenshot. However, when flashing the radar with the awr2x44P_ccsdebug.appimage appimage and load the mmw_ddm enet demo using CCS 20.2.0, tera term only displays an empty terminal and does accept any input. This prevents us from configurating and starting the sensor. The debug output in CCS from the R5 Cortex is the following:

    Hi Emil,

    I suggest you to run mmw_ddm demo without ENET first. Ensure that you perform CPU reset followed by loading program on each of the core. Click on "Run" to run application on each core one after the other i.e do not group the cores and run.

    Hey Samhitha,

    Thanks for the quick response. We've already tried without ENET when doing the initial debugging.
