Every boot, a random MAC address.

[stolk]

The ethernet ports get a random MAC address, every time the system boots.

How can I get a stable MAC? I want my router to be able to identify the Lichee Pi.

Hello stolk,

it seems to be an u-boot issue: In the UART Ai see:

MMC: sdhci@ffe7080000: 0, sd@ffe7090000: 1 Loading Environment from MMC... OK Error reading output register Warning: cannot get lcd-en GPIO LCD panel cannot be found : -121 splash screen startup cost 16 ms In: serial Out: serial Err: serial Net:

Warning: ethernet@ffe7060000 (eth1) using random MAC address - ce:49:41:74:e5:5d , eth1: ethernet@ffe7060000 Hit any key to stop autoboot: 0

And in config from u-boot is CONFIG_NET_RANDOM_ETHADDR=y set.

I tried setting it with ifconfig in if-pre-up.d/ but that did not work. I remember it working on sipeed rv86, but it does not work for pi4a.

Yes, it was weird, try sudo ifconfig
