Banana Pi BPI-R4 Ethernet ports died

evkogs · January 5, 2025, 1:44am

I have an issue with my Banana Pi BPI-R4 board, RJ-45 ports suddenly stopped working. Also 2 of the green LEDs are on for some reason. Issue occurred after flashing openwrt back and forth for some time.

I tried several images, including the banana original ubuntu image which worked before - same leds, no link on any port.

I’m attaching the boot logs of openwrt and ubuntu. In both logs this sequence is present:

I believe this is a hardware issue now :(( Extremely disappointed, as I was finishing building my tuned openwrt image…

Maybe I can figure it out on my own?

Thanks!

You can try to power it down for one minute by unplugging the cable.

Are the LEDs on from the start?

evkogs · January 5, 2025, 1:10pm

This won’t help unfortunately.

Originally everything worked both on ubuntu and openwrt.

I tried booting from sd, nand, this issue persist across 4 different OS images (3 different openwrts and one official ubuntu), ethernet switch can’t calibrate during boot.

Leds are turning on during boot at the specified moment - after kernel tries to initialize ethernet switch. LEDs are only symptom of the issue, none of rj-45 ports works.

I Have one ethernet port that only sync in 100Mbits

I have the same issue with lan2 and lan3 port. Were you able to fix it? Seems it is a HW issue?

This looks like there’s a hardware malfunction. If you’ve tried changing the image and the problem persists, please contact BPI to see if a replacement is possible.

Bogey · July 20, 2026, 2:15pm

I had used the same image for one year without an issue. Now also last lan1 broken, so the ports are degrading.

Upgraded version version to OpenWrt 25.12.5, r33051-f5dae5ece4 but that did not help.

I suspect it was broken by a surge, the cable was running to another building. Maybe replacing the magjack cluster would fix it.

@sinovoip what is the magjack model, can it be ordered from somewhere?

Now the cpu went dead, getting kernel oops, and new board is over 300€…

evkogs · August 7, 2026, 7:33pm

Hi,

No, my CPU died in 3-4 days after that. I bought the replacement, working fine since the original post basically. Likely banana has almostDeadOnArrival kind of issue and we are just unlucky.

Grigory.

I didn’t push hard on warranty, maybe you can push them on it
