We are facing 2 issues in our IMX6solo customised board.
- Failure to resume from a Deep Sleep Mode
- High Current in Deep Sleep Mode (~60mA)
After we checked the PMIC power rails with Reference design,
we found VIN3 in our design used 3.3V as input which was generated SW2 of the PMIC. We are taking the VDDHIGH_IN O/P power from VGEN6. So this may cause the issue?
VIN3 also need to be power SYS_4V2 ??? as like all Switching regulator input?
Please find the snap shot of PMIC circuitry design of our project.
