In any case the > number after @ in the node name should match the reg value. Hi，Emil，which board are you using? (v1.2a or v1.3b?). I have tested it on v1.2a and 1.3b, all network ports work normally when the phy address is set to 0. Maybe your eth1 doesn't work for other reasons? General, the phy address is fixed when the bord is designed. (For example,the phy address of YT8512 depends on the hardware resistance pull-up or pull-down. However, some phy addresses can be configured through software, but not yt8512.) The phy address is a borad-related attribute, and I will follow Andrew's suggestion and put the phy address in borad*.dts Best regards, Samin > >> + }; >> + }; >> + }; >> }; >> }; >> -- >> 2.17.1 >> >> >> _______________________________________________ >> linux-riscv mailing list >> linux-riscv@lists.infradead.org >> http://lists.infradead.org/mailman/listinfo/linux-riscv
