U-boot doesn't set dpmac.1?

NXP LX2160

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:

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.

4

just add something like the below?

&dpmac1 {
status = “okay”;
phy-connection-type = “xgmii”;
};

5

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

thanks!
