Hello,


Please submit IPS case if you need more support.


The possible root cause of your issue is :

  1. voltage drop
  2. Driver issue
  3. PCB design issue- decoupling capacitors not sufficient
  4. kernel issue
  5. timing issue


You need to monitor the voltage during power up and see if there is voltage drop during ramping up.

Please check the log file if there is error on driver or kernel integration issue.


regards,

Farabi
