    Hi Xiaoqian, 

    Were you able to run the out of box demo?  This should be done before trying any ROS based demos:

    In this case, we use the parameters of using mmwaveicboost to connect iwr6843ods and ros to collect point cloud data under Ubuntu18.04. Burning is TI's official uniflash 7.0, can confirm what caused the problem?

    Hi Xiaoqian,

    It is important for me to know if you have run the out of box demo successfully on your setup so I may rule out any hardware associated issues.  Once I can rule those out, I can more accurately diagnose your problem.

    Regards,

    Univash alone can be burned out of box, but plug in mmwave ICboost is not even uniflash, and another piece 6843 can be burned and used normally

    Hi Xiaoqian, 

    This may be a hardware related issue if what you are telling me is that you have another 6843 device that works as intended after following the same setup steps.

    Please ensure that you are following ALL steps in the out of box demo for the IWR6843ISK-ODS setup guide.  Ensure that you are following the steps for the use of the demo in MMWAVEICBOOST mode:
