CCS/IWR6843AOPEVM: Demo for IWR6843AOPEVM

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVEICBOOST

Tool/software: Code Composer Studio

Hi,

I was trying to run some demos on the IWR6843AOPEVM we recently purchased. Following the guide, I don't have any problem running the out-of-box demo (include running the prebuilt code, the rebuilt code and entering the debug mode). But this demo is only based on the HWA.

So I was trying to try a demo with both dss and mss. I picked the multi gesture recognition aop demo. However, I was not able to enter the debug mode by loading the pre-built code. After I loaded the two code, the console gave me an error saying:

" [Cortex_R4_0] Error: SOC Module Initialization failed [Error code -2905]".

One thing I noticed in CCS is, the sdk version included under the imported dss and mss projects for multi_gesture_68xx_aop is "03_02_00_04". But for the out-of-box demo, the sdk version included in the project is "03_02_00_06_AOP". I am not sure if this important. I tried changing the version 03_02_00_04 to version "03_02_00_06_AOP" from the "show building system" then rebuilt the ".xe674" and ".xer4f" files. But the demo was still not working as expected. 

toolbox version I tired: 4.0.0 and 4.0.1;

CCS version: v8.3.1, v7.4, and v9.1;

Could someone help me on this?

Another thing I read on the forum is some one is able to run the vital signs demo under debug mode using 6843AOP + MMWaveICBoost. If I want to do this, which ccsdebug file I should use? Which xe674 and xer4f file should I use for debug mode? (the post I read: https://e2e.ti.com/support/sensors/f/1023/t/842652)

Thanks a lot!

    Hi Yiran,

    The multi-gesture demo is based on SDK 3.2.0.4 so you should not change the SDK to 3.2.0.6_AOP.

    1. Did you flash your AOP EVM with the ccs debug binary xwr68xx_ccsdebug.bin from SDK 3.2.0.4 before attempting to run the code in debug mode? The corresponding instructions are available in the user guide section 4. Execute the lab under "Expand for help with Debug mode on IWR6843AOPEVM:". You'll need to click on this item to open the debug instructions.
    2. Are you able to get CCS debug working with the pre-compiled AOP binaries, namely multi_gesture_68xx_aop_dss.xe674 and multi_gesture_68xx_aop_mss.xer4f"? Again, please follow the instructions pointed in item 1.
    3. Please use only CCS 8.3.1 as mentioned in the user guide to rebuild the project (get to this once you have the pre-compiled CCS debug binaries working).

    Thanks

    Yiran,

    Also note, that you will need the MMWAVEICBOOST carrier card to run the AOP demo in debug mode as detailed in the instructions pointed above.

    Thanks
