hi, 

we got issue when design new iMX6ULL.

Board can boot via usb and can working but i detected issue with pin (ball pin number : p12, pin nam: VDD_SNVS_IN)

   - follow spec that pin is input power 

   - but i checked this pin may be out put and always 4.4 V. 

   - my design used PF3001 for PMU, ( 4.4v come out before 5V go through mostfet and supply for PF3001)

   - Checked and no sorted 4v4 with VDD_SNVS_IN, but so stranger 

anybody have same issue 

plz advise 

Thanks
