  • we have no idea which of the hundreds of possible "evaluation boards" you have, so ... the answer is a pineapple – Jaromanda X Jan 9 at 9:54
  • I think I have seen Kuman boards with this, but you can trigger the same thing without the button. However, until we know which board this is, there's not much anyone can say. – goldilocks Jan 9 at 15:09
  • @JaromandaX fun part is I am not able to find the name of evaluation board ,this seems to be some Chinese board – Karthikeyan M V Jan 10 at 10:24
