Routerstation not getting its MAC address #13299

Closed MarkTerMors closed 1 year ago

MarkTerMors commented 1 year ago

Describe the bug

When booting up 22.03.5 on Ubiquiti Routerstation (ath79) the device does not load its MAC address [ 0.997422] ag71xx 19000000.eth: invalid MAC address, using random address

OpenWrt version

OpenWrt 22.03.5, r20134-5f15225c1e

OpenWrt target/subtarget

ath79/generic

Device

Ubiquiti RouterStation

Image kind

Official downloaded image

Steps to reproduce

Happens at boot.

Actual behaviour

A random MAC is used.

Expected behaviour

The MAC stored in the device flash should be used.

Additional info

I can find the MAC by doing

fconfig -l -d /dev/mtd7 or hexdump -x -s 23 -n 6 /dev/mtd7

but have no idea how to go about making the kernel find it there.

Diffconfig

No response

The ag71xx has no capability to fetch MAC from that location (that's why the message in kernel log), therefore userspace fallback is in place. To see it run grep -A 4 'routerstation|' /etc/board.d/02_network on the router. This fallback sets the MAC for lan and wan interfaces, so You should have eth0 MAC set from ar7100_esa value while br-lan has ar7100_esa + 1. Is that not the case for Your device?

MarkTerMors commented 1 year ago

No, that doesn't seem to work. It looks like I'm getting random MAC addresses. Probably because I don't have "lan" and "wan" interfaces. Changing "br-lan" to "wan" doesn't provide a solution.

I assume You've never reset the devices settings on sysupgrade, which is mandatory when going from ar71xx to ath79, because /etc/board.d/02_network is only sourced when /etc/config/network is created. Try to reset the board running firstboot -y && reboot (backup Your setting), and check MAC address after reboot. If You don't want to reset settings, set macaddr option in device section for each ethX, it should look like this in Your case:

config device
        option name 'eth0'
        option macaddr '00:15:6d:c1:2c:a5'

Not sure about the reset. I tried many things which involved reset and force. Regardless, it fine now. Many thanks.

tmn505 commented 1 year ago

So I guess You can close the issue, as this is more of an support question rather than a bug.
