Hi, We are trying to set the mac address but it seems the kernel does not see it: Setting in eeprom works fine: => tlv_eeprom set 0x24 00:23:45:67:89:AB => tlv_eeprom set 0x2A 2 => tlv_eeprom write Programming passed. After boot u-boot seems to see this fine too: => tlv_eeprom TLV: 0 TlvIn…

The general consensus from the developer working on u-boot for the lx2160a is that the fdt_fixup does matching of MAC → address, so the device-tree is not updated properly with the MAC for the onboard NIC as it is MAC 17 and you only have 2 MACs setup. You can verify this by dumping the device-tree …

Inside u-boot/board/freescale/lx2160a/lx2160a.c I do see this function: void fdt_fixup_board_enet(void *fdt) { int offset; offset = fdt_path_offset(fdt, "/soc/fsl-mc"); if (offset < 0) offset = fdt_path_offset(fdt, "/fsl-mc"); if (offset < 0) { printf("%s: fsl-mc node not found in device…

Thanks! Checking this, I have set: => tlv_eeprom set 0x24 00:23:45:67:89:00 => tlv_eeprom set 0x2A 17 => tlv_eeprom write Programming passed. => tlv_eeprom TLV: 0 TlvInfo Header: Id String: TlvInfo Version: 1 Total Length: 18 TLV Name Code Len Value -------------------…

[image] joema: fdt_fixup_board_enet There is not way to do this via the existing mechanisms. You could create a custom function for u-boot that specifically patches the rgmii node to use the first MAC address and then start from MAC + 1 for the other interfaces.

ok it’s a bit awkward, but if I want eth0 to have 00:23:45:67:8a:00 then I need to set: => tlv_eeprom set 0x24 00:23:45:67:89:F8 => tlv_eeprom set 0x2A 9 then eth0 will get the 9th entry after F8 which is 00. hope i’m not missing some other more elegant way. thanks for the help!

Without patching the existing u-boot code, then yes that is the only way.
