For VLDO_1V8 voltage on MX6UL-EVKB board

Dear all,

 

We want to test eMMC Boot on MX6UL-EVKB board.

We attached 1.8V eMMC to MX6UL-EVKB board.

And the R701 was removed and attached 0hom register to the R702.

 

Please see the SPF-28617_C2.pdf

VLDO_1V8 voltage for MX6ULEVKB.png

 

However, the output voltage of VLDO_1V8 was 2.1V

We cannot use this power supply source for eMMC because the input voltage of VCCQ of eMMC is 1.8V(1.65V to 1.95V).

 

We checked RT9169-18GVL(U705) which made VLDO_1V8.

But, BG=307 is listed on the U705 parts.

 

Is this U705 a correct part?

 

Best Regards,

Yuuki
