Original question:

IWR6843: IWR6843: Problem with BSS power up

IWR6843: Can't get any demo working with IWR6843ISK + MMWAVEBOOST

Part Number: IWR6843

I recently purchased these debug modules and haven't been able to get the OOB demo working, nor any of the labs in the SDK.  I was able to get the OOB demo building in CCS and am able to load the debug version onto the target but it seems to hang right after the data uart is initialized.   It seems like the next thing should be the mmWave control module initialization.

    Hi Billy,

    Please flash the mmw demo binary from the latest mmwave sdk 3.1.1.2 and select the same SDK when runnin the demo with mmWaveDemoVisualizer. There was a firmware issue in SDK 3.0.0.8 which could cause the power-up sequence to lock-up and this has been resolved in SDK 3.1.1.2.

    We have also updated the IWR6843 labs in Industrial Toolbox to use the latest SDK. These updates are available in Industrial Toolbox version 3.2.0

    Hi Billy,

    In order for us to debug the issue, could you please follow the instructions below and provide a CCS stack trace for the OOB demo at initialization?

    1. Follow the instructions provided in section 3.2.2: CCS development mode, to run the OOB demo in CCS mode. Please use the pre-compiled binary  Cortex R4F binary under C:\ti\mmwave_sdk_03_01_01_02\packages\ti\demo\xwr68xx\mmw\xwr68xx_mmw_demo_mss.xer4f. Please make sure that you flash the ccs_debug.bin from SDK 3.1.1.2 as well since the ccs_debug.bin from SDK 3.0.0.8 has the firmware issue

    Note that the 68xx SD OOB demo does not require the DSP so you can leave the DSP unconnected in CCS.

    You should see output similar to the following in the CCS console:

    2. Halt the R4F core using the pause button in the CCS toolbar and take a snapshot of the function call trace as shown below. Please provide the call trace snapshot from your EVM for the failure condition.

    Thanks

    For the record the only SDK I've ever used is the 3.1.1.2 (I just got this board last week)

    I re-ran through this taking some screen shots but its the same result, it never makes it to the mmWave Control Initialization.. is it possible this is a hardware issue?
