Hi
In our custom board design with i.MX8DualXPlus / i.MX8QuadXPlus, based on the MEK, we do not require the Ethernet functionality. The hardware developer guide does not mention about the i.MX8 QXP unused input/output guidance for ethernet signal IO's.
Can we leave them unconnected as shown below:
Please advise.
Regards

Hello,
According to i.MX8 QM/i.MX8 QXP Hardware Developer’s Guide, the following takes place for
Ethernet pins: digital I/O supplies can be left unconnected when the associated I/O balls are
not in use (left floating).
CAUTION:
Driving/connecting associated I/O balls is prohibited when the supply isn’t powered.
Also, the Ethernet pins can be configured as GPIO, in such case the supply voltages must be applied.
Regards,
Yuri.
