I made a board with reference to SPF-28857, but I found that when NVCC_RGMII (pin is G18) is not supplied, NVCC_RGMII itself has a voltage of about 3V. Why?
Then I don't power NVCC_ENET and found that NVCC_ENET itself has a voltage of about 2.8V.
I don't understand why they have voltage.
In IMX6DQCEC, the voltage range of NVCC_RGMII is 1.15V to 2.625V.
