Hi community,

 

I have a question about i.MX6QP BSP.

Please see around line 1000 of the u-boot source code <u-boot>/board/freescale/mx6sabresd/mx6sabresd.c in L4.1.15_1.0.0-ga.

It seems that VGEN3 and VGEN5 of MMPF0100 are changed its voltage regardless whether the chips is i.MX6QP or not.

However, as per the schematics of i.MX6QP SABRE, I feel these voltage changing are not needed.

Why these voltage changing are executed not only for i.MX6DQ SABRE but also for i.MX6QP SABRE also?

 

 

Best Regards,

Satoshi Shimoda
