Hello Team,

I am using IMX8QXP processor and PMIC MC33PF8200DEES in my custom board.

When board power ON test, i observed SW3 and SW4 output voltages are not getting from PMIC.

We know that DE otp report says it is disabled kindly let us know how to turn on the SW3 and SW4 voltages and power sequence
