It turned out for the Ethernet port i wont use the SDIO interface but MIIG , i used the RTL8211F-CG and a ethernet port with includet magnetics . This time there were no reference designs , and as i didnt want to go back and forth searching for the pins of this interface on the rockchip , I used AI to search for them and made a quick check if the Ai is telling false statements by manual checking !
