ethtool replying MII

Hi All,

I am trying to connect ethernet driver with on our custom IMX6UL board with TI PHY DP83822 .

Once booted I get following log(filtered):

I can see the driver is registered. I have set RMII Phy mode in device tree.

But when I do ethtool eth0, it gives me the following output:

Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supported pause frame use: Symmetric
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Speed: 10Mb/s
Duplex: Half
Port: MII
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Link detected: no

Does it mean my device is not set in RMII mode, because I am not able to ping as well.

It gives me host unreachable?

Hello,

  is it possible to look at the RMII schematic between i.MX and the PHY?

How RMII REF_CLK is connected?

Regards,

Yuri.
