PMIC power on issue during start-up

Hi, 

 

  we have designed a system by using iMX 6 solo processor with PMIC MMPF0100.

  which gives an issue during power up.. while giving power to the system for the first time it doesn't booting.

 

if you give power again within some few seconds it starts booting and functioning properly.

while checking power on sequence during first plug-in we found VDD_HIGH_IN not generated which gets power from PMICs VGEN 6.

 

Could anyone suggest me what is the issue and relevant workaround.

 

thanks.

Santhakumar.
