DP83822I: MDIO communication error

Hi Team,

An MDIO communication error occurs in DP83822I.

I tried MII communication with the MCU using DP83822EVM, but it will be successful.

Is there a difference in hard connection between DP83822HF and DP8322I?

In EVM, after RESET, RX_ER goes high and goes low, and RX_CLK starts outputting at the same time.

However, in the mounted DP83822I, RX_ER does not fall to Low and RX_CLK is not output.

Do you know what is the factor?

Best Regards,

Kenji
