Good day.
The EG512R-EA module in the documentation for AT commands indicates that RGMII can operate with a voltage of both 1.8 and 2.5V.
Command: AT+QETH=“rgmii”

But in the documentation “Quectel_EG512R-EA_Hardware_Design_V1.0” it is indicated that the voltage of the RGMII is determined by the RGMII_PWR_IN pin. This pin does not support a voltage of 2.5V.

Tell me, is it possible to use a voltage of 2.5 for the RGMII and MDIO?
