Hi There,
I want to check for "MCIMX7D-SABRE Rev.D".
MCIMX7D-SABRE is connected to the PMIC_PWR to VLDO34IN.
PMIC_PWR is 3.7V supply power.
PMIC data sheet has the following description.
Document Number: PF3000 Rev. 7.0, 9/2016
Absolute maximum ratings of VLDO34IN is "-0.3 to 3.6V"
This will be the fact that in violation of the spec.
Is this the SABRE board right connection ?

Hi, igor
Thank you for your reply.
There is a power map in the PMIC data sheet.
Figure 5. PF3000 typical power map
Here, VIN is connected as a power source of VLDO3 / VLDO4.
(VIN is typical 4.5V?)
VLDO34IN is Will voltage range of 2.8-3.6V is correct?
However, VLDO1 is 2.8-4.5V becomes the input power supply in the same configuration.
