eth0 disappears

[frm]

Hi all,
I just unboxed my shiny new A64, imaged with the "A64-OLinuXino-bullseye-base-20231106-081613.img" image (stored on SD card).
I do have also the MOD-WIFI-RTL8188EUS-ANT part, so I expect to have 2 ethernet interface: the wired RJ45 eth interface and the wireless one.

Surprisingly, the first one is what's giving me troubles (wired Eth interface).
On the first boot I actually did have "eth0". Then I think I rebooted after reading a message about the DTS tree initial setup being completed (IIRC).
After reboot eth0 was disappeared. I read some thread about Eth interface being multiplexed with the LCD display so I used the "olinuxino-display" utility to set LCD mode to DISABLED. Reboot. Eth0 was there.

Now after another reboot eth0 is gone again.
I tried again to set LCD to DISABLED with "olinuxino-display" and rebooted. Eth0 is still not there.
This is what I see in kernel log:

is this a known issue?

I can copy here also the boot log taken from UART:

I guess that "Could not get PHY for ethernet@1c30000: addr 1" might be a sign of an HW issue?
If that's the case I hope I can return the board and get a new one cause it's fresh new.

1. What is the state of the PHYRST1 PTH jumper? Is it closed or open? You also need to open that jumper in conjunction with running the script.

2. What exactly is the name and variant of the A64 board that you got (as printed on the box)? So I can test it myself.

It's open

This is an A64-Olinuxino-1G board, PN 88575


Thanks!

It behaves the similarly up to a point here. On first boot Ethernet works just fine, after a reboot settings for LCD output get loaded and Ethernet stops. However, here when I run "olinuxino-display" and select the bottom option - "DISABLE" and perform a reboot, the Ethernet starts working.

This is my bootlog after running "DISABLE" and rebooting:

That line is indeed different. Can you try a different LAN cable? Also try re-writing the card and check if it works again before rebooting.

Maybe also test with the Armbian image (root/1234) from our FTP: https://ftp.olimex.com/Allwinner_Images/a64-olinuxino/linux/1.latest_images/bionic/images/Armbian_5.92.1_Olinuxino-a64_Ubuntu_bionic_next_5.2.5_desktop_emmc_fix.img.7z
