Hi community,


Our customer have a question about i.MX6DQ SABRE and Linux BSP.

Please see the schematics of i.MX6Q SABRE platform, VGEN5_2V8 is used for VDDHIGH_IN power supply.

And VGEN5 is changed the output voltage from 2.8V to 3.0V by u-boot.

Our customer want to know why it is changed to 3.0V.

We know the min voltage to i.MX6DQ VDDHIGH_IN has been changed to 2.7V, so we think 2.8V supply from VGEN5 is no problem.

Although, the voltage changing has been remained in u-boot of latest BSP.

Would you let me know the reason?
