Board not booting up

Hello ,

I would also like to share one of my observation,

  1. If we do not connect SoM to our carrier board and power-up the board , their is no power glitch in POWER_EN line of SoM.

  1. But , whenever we connect the SoM in carrier board and Power Up it , we observe a ver very small glitch (the power get low for 4.3 usec, pls see in image power_glitch_while_SOM_is connected.jpeg) in power squencing at pin POWER_EN ,
    Is this the reason that Our SoM is not booting.
