Hello,
I asked beforehand about imx6q's ability to use RGMII & MII peripheries in the same time (Can these peripheries be active in the same time)?
answer: IMX6Q has ENET module, which supports MII, RMII, RGMII interfaces Pins affected are described in Table 23-1 (ENET External Signals) of the i.MX6 RM (Rev. 3, 07/2015). Only single interface may be used at a time because of multiplexing.
what is the origin of multiplexing? is it pin mux or other kind?
please elaborate.
Regards,
Eli
Yes, the IOMUX multiplexing is meant here.
Moreover, i.MX6Q has only single Ethernet MAC core, so, only one PHY and only one Ethernet interface can be used at a time.
Have a great day,
Artur

As far as I can see RGMII doesn't use any of the pins of the MII, where does the multiplexing takes place?
Thanks
Eli
When the RGMII interface is selected, the MII signals become non-functional. So, as I told before, only one interface is functional at a time.
