Hi igorpadykov

Thank you!

But.. 10Base-T hulf ping test faild in my custom i.mx6Q board.

I was examined.

I had good result in the setting below.

Register 18[14bit] 10BT HD Loopback Disable = 1 (Disable).

1. i.MX6 unsupported "10base-T hulf loopback" ?

2. i.MX6 need Loopback mode disable in PHY?

>i.MX6 need Loopback mode disable in PHY

I believe yes, however better if you would consult with

phy datasheet.
