We are having an issue on our boards with the SWBST boost output is coming up initially as 4.3V and not 5V.  When the kernal boots; we program the PMIC to 5.15V and this seems to happen correctly, but the initial turn at 4.3V is causing issues across our system.  Any thoughts what could cause this?
