BPI-R4 SFP guidance

[TheUnwiseOne]

Edit for anyone who comes across this: The Ipolex ASF-GE-T 1.25gb SFP does work. The issue seemed to end up being the OpenWRT snapshot was missing kmod-phy-realtek, once installed and rebooted it immediately detected it and worked.

I’m somewhat new to this and trying to get an SPF to work in my BPI-R4. I bought this one just to test out (https://www.amazon.com/dp/B01HDABJJA) (Ipolex ASF-GE-T 1.25gb SFP to RJ45) as it is a Marvell based one I could get quickly and cheaply from Amazon and had read on here that Marvell based SFPs tend to be compatible.

If this SFP isn’t compatible that’s fine, I just don’t know enough to determine that myself. If it is incompatible, can anyone recommend one (fast shipping on Amazon would be great, but AliExpress is okay too if need be) that works for 1gig but preferably also for 2.5gb/5gb? I don’t foresee a 10gig connection in the near future but may go for 2 or 5 so having those as an option without replacing the card would be great.

Below is what I’ve tried and as much diagnostics as I can think to provide:

I have it in Eth2, but cannot get it installed. When I insert it I get: 
> [ 4449.050740] sfp sfp1: module OEM              SFP-GE-T         rev      sn CSGE4NB5643      dc 23112801

> [ 4449.158185] sfp sfp1: sfp_add_phy failed: -EINVAL


If I try installing kmod_phy-marvell and kmod-phy-marvell-10g it says they are installed in root and up to date but also gives a "pkg_hash_check_unresolved... cannot find dependency kernel" error.

I had previously run 
>ethtool -s eth2 speed 1000 duplex full autoneg off

There is no output from that. 

dmesg | grep firmware just gives:

and dmesg | grep -i eth2 gives:

@TheUnwiseOne

gives a “pkg_hash_check_unresolved… cannot find dependency kernel” error.

That means you need to update to latest snapshot as the kernel installed no longer matches the version of the modules available for download.

You may auto-update to the most recent snapshot using

opkg update
opkg install owut
owut upgrade

That should solve it.

Much appreciated, thanks!

Your sfp module might has a broken eeprom data, more information related here:

SFP OEM SFP-2.5G-T kernel PHY?

I was looking into the SFP OEM SFP-2.5G-T, reading also about the patch to kernel… From Russel King: If its not ethtool, then there is only one other possibility which I thought had already been ruled out - and that is the PHY is actually accessible, but either we don’t have a driver for it, or when reading the PHY’s “features” we don’t know what it is. Therefore, as the PHY is accessible, we need to identify what it is and have a driver for it. From the command: [root@bpir3 ~]# i2cdete…

[BPI-R4] and SFP

For more info from kernel, do this before inserting sfp: echo "file drivers/net/phy/* +p" > /sys/kernel/debug/dynamic_debug/control Hopefully dynamic debugging is enabled… Then it shows more on how mac is configured… 1000Mbps sgmii leave autoneg on. It is only broken for 2500base-x. Disabling it may break it.

It would be better if you could provide ethtool -m output of your module(Please use full version of ethtool)
