Hi All:
I am hardware newbie. We are design custom board with Marvell AQR113C like down pic

but Nvidia reference design is

Here is my question:
Is necessary WOL_POWER_ON_N?
If necessary, could it poll high 3.3V?

WOL_POWER_ON_N is to button MCU. If your design is using same Ethernet PHY and same button MCU to devkit, then please follow the reference design well.
