Hi all,

We are using imx6solo custom board. In this we have MMPF100 - pmic IC. I configure this pmic in uboot and kernel also. i got the PMIC detecetion log in uboot and kernel also.

 

In u-boot log:

VGEN6: 1800 <--> 3300 mV at 3300 mV

Serial: IMX driver

 

 

From boot log i think PMIC configuration is proper. But we check in hardware the voltage is not reduced and also processor is heating.

How to fix it??
