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

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 From: Bram Stolk ***@***.*** Sent: Monday, May 22, 2023 8:38 PM To: sipeed/LicheePi4A ***@***.***> Cc: Subscribed ***@***.***> Subject: Re: [sipeed/LicheePi4A] Every boot, a random MAC address.
