Other Parts Discussed in Thread: IWR1642
Well!
Something strange discovered. I had many IWR1642Boost and I was testing with only one board. Surprisingly, It's working without any problem with other boards. So I am assuming that there is something wrong in the IWR1642Boost itself.
And people count demo is working fine with this board.
So the question is here that why Vital is not working and People Count is working if the board is defective? If the board is not defective then it should run both examples. Another board is running both examples fine.
