BPI-R3 2.5GB Ethernet not working for me

Banana Pi BPI-R2/BPI-R64/BPI-R3/BPI-R3 Mini/BPI-R4

Hello,

Do I have to enable something to make the Ethernet ports 2.5GB ? Doesn’t seem to work for me. I have verified cables, and switch port. I am using image, openwrt-23.05.0-rc3-92a7d087de39-mediatek-filogic-bananapi_bpi-r3-sdcard.img

Everything seems to work, though, haven’t tested the 10GB Ethernet ports, yet…

From menu item, Status, System Log,

  • Mon Sep 11 15:09:28 2023 kern.info kernel: [ 1645.894856] mt7530-mdio mdio-bus:1f lan1: Link is Up - 1Gbps/Full - flow control rx/tx

There are no 2.5g “ports”…the sfp cages have 2.5g backend. Here should be noted that right one is connected to switch which also serves the 5 rj45 ports (1g) and also connected with 2.5g to cpu. So having traffic on the rj45 ports will reduce traffic on lan-sfp.

10gbit/s? Upcoming bpi-r4 will have 10g sfp+ ports,but on r3 these are max 2.5g

Ahh, there’s my “problem”, rushing into things again. Thank you for the clarification!

Okay, time to read the SFP threads…

i bought this one : https://www.aliexpress.com/item/1005003922625830.html

but unfortunately it doesn’t seem to support 1G, But TP-Link says it should work at 2.5/1G

i’m wondering if it is not a counterfeit ?

Yes and there are some patches from @ericwoud to get them completely working. Current linux only works in 2.5g mode only…lower speed is not detected,and will cause retransmitts

For tplink version it seems to need special handling

8

the patch is in the snapshot ? or do we have to compile our own firmware with this patch ? if yes then where can we find it ?

i move the discussion about the TL-SM410U here

9

No,not yet merged anywhere…SFP OEM SFP-2.5G-T kernel PHY?

I only have a patched mainline kernel here:

You can use it with debian.

Pre-build archlinux package:

ftp://ftp.woudstra.mywire.org/test-builds/aarch64/linux-bpir64-git-6.5.0.rc6.bpi-1-aarch64.pkg.tar.xz

If you know how, can use the binairies inside.

Hmm, I just bought the TL-SM410U from eBay yesterday. Shrug, I want to use it at 2.5GB anyways…
