Hello,

Made a Ethernet interface with DP83867IRPAPR as attached schematic, but it doesn't work.

Could you check attached schematic and register setting, and let me know if there is any fault?

1. Schematic : K2E_1G_DP83867IRPAPR_SCH.PDF

2. Register setting with 100M LAN Hub connection : DP83867-B.png

3. RTX_CLK, GTX_CLK : 25MHz measured. & CLK_OUT : 125MHz( TX CH A ) measured.

Regards,

Nicky

Hi Nicky,

On PHY 1, status register indicates "796D" means link is up. Register 0xF indicate link speed is "1000Base-T".

Please be more specific on what's not working : Data transfer and which direction ?? DId you try adjusting the Clock and Data skew ?

Nicky,

What is that UKenDebug software you are using? Is it something available online? It looks nice.
