Hi,

couple of questions related to IMX6S powering.

Question 1

In our design there is no coin battery and VDD_SNVS_IN is shorted to VDDHIGH_IN. This supply (3V0) is the first in the power-up sequence. To simplify power supply would it be ok to connect also NVCC_GPIO (and other 3V3 level NVCC pins) to this same supply and use voltage level of 3.3V?

Question 2

RGMII mode is not used but as instructed by datasheet NVCC_RGMII is connected to voltage regulator. According to measurement current is negligible. Probably ok to supply NVCC_RGMII using resistor divider?

Thanks!
