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?</P><P><STRONG>Question 2</STRONG></P><P>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?</P><P>Thanks!</P> Tue, 27 Jul 2021 07:14:48 GMT wayne_1 2021-07-27T07:14:48Z https://community.nxp.com/t5/i-MX-Processors/IMX6S-power-sequence/m-p/1313683#M177503 <P>Hi,</P><P>couple of questions related to IMX6S powering.</P><P><STRONG>Question 1</STRONG></P><P>In our design there is no coin battery and VDD_SNVS_IN is shorted to VDDHIGH_IN.
