IWRL6432BOOST: Unable to complete the CCS Debug with IWRL6432 demo

Halldor Laxdal
Prodigy 40 points
Part Number: IWRL6432BOOST

Executing the demo as instructed goes well until the very last step.

When pressing resume, the console reads as follows and does not progress further than that until I either disconnect or manually stop the demo, but still the console remains unchanged.

- [Cortex_M4_0] Calibration Validated for restore

The switches on the device are as follows and are copied directly from both the image in the document and the description on the same page:

S1: 110010

S4: 0001

I am unable to communicate with the device over UART via the USB link included and a super simple python script using the Serial package but running all Visualizer demos works as intended.

    Hi,

    Can you describe the problem a little more to me or provide some screenshots of what you're seeing? Are you able to set any breakpoints in the code to see where the program is failing?

    I am not sure what you mean by this, and when this is happening. Any more details would be appreciated and I will better be able to assist.

    Regards,

    Tim

    The issue is that the last slide in the guide states that the console should say

    [Cortex_M4_0] Calibration Validated for restore
    Debug: CLI is operational

    but it never gets to the second line, it just hangs there after the first one, still running and nothing changes. No errors are reported after the program and the memory are loaded on in accordance with the guide, but I am unable to see any other errors or indicators that anything went wrong.

    The CCS version I have is 12.3.0, the demo code I run is located at <Workspace>\motion_and_presence_detection_demo_xwrL64xx-evm_m4fss0-0_freertos_ti-arm-clang\Debug\motion_and_presence_detection_demo_xwrL64xx-evm_m4fss0-0_freertos_ti-arm-clang.out.

    Running the wake up gel yields the following console output:
    CS_DAP_0: GEL Output: Starting FEC Memory Init
    CS_DAP_0: GEL Output: FEC RAM Memory Init Completed
    CS_DAP_0: GEL Output: FEC Shared RAM Memory Init Completed
    CS_DAP_0: GEL Output: FEC Patch / Data RAM configuration Done
    CS_DAP_0: GEL Output: APP RAM1
    CS_DAP_0: GEL Output: APP RAM2
    CS_DAP_0: GEL Output: APP RAM3
    CS_DAP_0: GEL Output: APPSS RAM configuration
    CS_DAP_0: GEL Output: HWASS SHRD RAM0
    CS_DAP_0: GEL Output: HWASS SHRD RAM1
    CS_DAP_0: GEL Output: HWASS SHRD RAM0 configuration
    CS_DAP_0: GEL Output: device_wakeup in application mode done
    CS_DAP_0: GEL Output: M4 reset released

    The following screenshot is what I see after having loaded and resumed the demo as instructed in the file:


    Cheers.

    Hi,

    Try the following sequence:

    1. Hit pause

    2. Hit the "Reset" button (Black Computer chip logo)

    3. Hit the "Restart" button (back arrow just to the right of the Reset Button)

    This will reset the CPU and should put you back at the beginning of main. Sometimes this is necessary when you enter into debug mode.

    Regards,
    Tim
