How to Enable TI DP83867 Ethernet PHY in U-Boot for i.MX8MP Custom Board

[Ramkumar_Somesthree]

Hello NXP Team,

I’m working on a custom i.MX8M Plus (i.MX8MP) board (not an EVK) and trying to bring up Ethernet in U-Boot using a TI DP83867 PHY connected over RGMII interface to the on-chip FEC (Fast Ethernet Controller).

I’m currently using U-Boot version: u-boot-imx-2020.04_2.3.2-phy6.
The Linux side of Ethernet is already configured and functional, but in U-Boot, I’m seeing the following message:

Could not get PHY for FEC0: addr 0
No ethernet found.

Hello,

Please make sure that the phy is correctly configured on the uboot level, either on device tree or driver may not be loaded.

I would suggest to reach your vendor for more information on how to do this.

Best regards/Saludos,
