how do I set the address of dpmac.1? Even if I use 17 entries in tlv\_eeprom: Base MAC Address 0x24 6 FA:00:E7:00:00:00 MAC Addresses 0x2A 2 17 I don’t see any u-boot configuration of dpmac1: Net: eth0: DPMAC3@xgmii, eth1: DPMAC4@xgmii, eth2: DPMAC5@xgmii, eth3: DPMAC6@xgmii, eth4: DPMAC7@xgmii, eth5: DPMAC8@xgmii, eth6: DPMAC9@xgmii, eth7: DPMAC10@xgmii, eth8: DPMAC17@rgmii-id [PRIME] And indeed if I bring up eth1 (bound to dpmac.1) its mac address is random: # dmesg | grep mac [3.553631] fsl\_mac: fsl\_mac: FSL FMan MAC API based driver [5.374262] fsl\_dpaa2\_mac dpmac.17: Adding to iommu group 3 [5.381445] fsl\_dpaa2\_mac dpmac.1: Adding to iommu group 3 # ls-addni dpmac.1 [44.132557] fsl\_mc\_allocator dpbp.1: Adding to iommu group 3 [44.140511] fsl\_mc\_allocator dpmcp.53: Adding to iommu group 3 [44.148359] fsl\_mc\_allocator dpcon.31: Adding to iommu group 3 [44.155740] fsl\_mc\_allocator dpcon.30: Adding to iommu group 3 [44.163464] fsl\_mc\_allocator dpcon.29: Adding to iommu group 3 [44.170983] fsl\_mc\_allocator dpcon.28: Adding to iommu group 3 [44.178377] fsl\_mc\_allocator dpcon.27: Adding to iommu group 3 [44.186084] fsl\_mc\_allocator dpcon.26: Adding to iommu group 3 [44.192935] fsl\_mc\_allocator dpcon.25: Adding to iommu group 3 [44.199596] fsl\_mc\_allocator dpcon.24: Adding to iommu group 3 [44.207119] fsl\_mc\_allocator dpcon.23: Adding to iommu group 3 [44.213937] fsl\_mc\_allocator dpcon.22: Adding to iommu group 3 [44.221549] fsl\_mc\_allocator dpcon.21: Adding to iommu group 3 [44.228344] fsl\_mc\_allocator dpcon.20: Adding to iommu group 3 [44.235607] fsl\_mc\_allocator dpcon.19: Adding to iommu group 3 [44.243123] fsl\_mc\_allocator dpcon.18: Adding to iommu group 3 [44.249939] fsl\_mc\_allocator dpcon.17: Adding to iommu group 3 [44.257625] fsl\_mc\_allocator dpcon.16: Adding to iommu group 3 [44.264715] fsl\_dpaa2\_eth dpni.1: Adding to iommu group 3 [44.458785] fsl\_dpaa2\_eth dpni.1: Probed interface eth1 Created interface: eth1 (object:dpni.1, endpoint: dpmac.1) # ip a … 4: eth0: \ mtu 1500 qdisc mq state UP group default qlen 1000 link/ether fa:00:e7:00:00:08 brd ff:ff:ff:ff:ff:ff inet 192.168.68.64/22 metric 1024 brd 192.168.71.255 scope global dynamic eth0 valid\_lft 7158sec preferred\_lft 7158sec inet6 fe80::f800:e7ff:fe00:8/64 scope link valid\_lft forever preferred\_lft forever 5: eth1: \ mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether ce:89:2a:a8:0f:92 brd ff:ff:ff:ff:ff:ff ---

it seems u-boot/arch/arm/dts/fsl-lx2160a-cex7-8-x-x.dts sets only dpmac3 - dpmac10 and dpmac17: &dpmac3 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac4 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac5 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac6 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac7 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac8 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac9 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac10 { status = “okay”; phy-connection-type = “xgmii”; }; &dpmac17 { status = “okay”; phy-handle = \<&rgmii\_phy1\>; phy-connection-type = “rgmii-id”; }; ---

Yes, this will need to be adjusted for different networking configurations. ---

just add something like the below? &dpmac1 { status = “okay”; phy-connection-type = “xgmii”; }; ---

and remove the interfaces that it will replace. These can be referenced in the LX2610a reference manual in the SERDES configuration section. ---
