iMX6 Dual: Unused PCIe and SATA Power

See the table 2-21 in the "Hardware Development Guide for i.MX 6Dual/6Quad and i.MX 6Solo/6DualLite Applications Processors, Rev. 1"

Table 2-21. Recommended connections for unused analog interfaces

 

The "Recommendation if unused" column states to "Ground" the SATA and PCIE power pins.

However, Sheet 18 of the schematic Rev. C for the QWKS-SCMIMX6DQ Quick Start Board shows these pins to be not connected.

Can anyone describe the discrepancy, please?

For our design, which is the best way to go on these 5 pins?  For minimum excess power consumption.  If it makes a difference to the answer, we are designing with an SCM-i.MX6 Dual.

 

Regards,

Stephen
