U-boot probe emac correctly but, kernel does not. There were two issues. 1. U-boot specified compatible for RTL8211 in dts, but kernel. -. https://patchwork.ozlabs.org/project/uboot/patch/20230711003957.658805-2-retpolanne@posteo.net/#3148293 2. Kernel require reset pin for it and controlling. -. Add reset pin gpio PD14 and its delays.

Subject: [PATCH] dts orange pi one plus Add Enable Ethernet
|
|
|
|
1. Add compatible to specifiy RTL8211.
|
|
This was fixed in U-boot.

|
2. Add reset pin definition(PD14) for RTL8211.
|
|
reset pin is required for if up/down function.
