Problems with SFP module FS model SFP-FE-BX

Hi,
I already saw that there is a list of supported SFP modules, but unfortunately the one I received from my provider does not seam to work. Because I’m not completely sure if I have missed something i wanted to ask if somebody could give me some advice:

I tried to manually link to the correct .dtb file by ln -sf armada-385-turris-omnia-sfp.dtb /boot/dtb && reboot but the modules does not seam to work.

This is what I got:

root@turris:/tmp/log# dmesg | grep eth2
[    1.851447] mvneta f1034000.ethernet eth2: Using device tree mac address d8:58:d7:01:05:d5
[    8.437540] mvneta f1034000.ethernet eth2: initial validation with support 0000000,00000000,c0758cdc failed: -22
[   12.704390] mvneta f1034000.ethernet eth2: configuring for inband/sgmii link mode

root@turris:/tmp/log# dmesg | grep sfp
[    8.084766] sfp sfp: Host maximum power 3.0W
[    8.428186] sfp sfp: module FS               SFP-FE-BX        rev A    sn C1903025459      dc 190308  

Turris OS version	6.3.3
Kernel version	5.15.114

The module works fine if I use a media converter…

Is there something i can do or do I have to change the SFP module?

I may be missreading this - is your SFP listed in the list of supported modules or not?

Regarding the module itself - it has to be “universal compatible”. Several users made good experiences with FS.com-modules. So if the provider SFP does not work, they could tell you the specifications and you can order the respective module there.

Sorry, your right - my sentence does not make any sense :sweat_smile:. I meant that I found the list of supported modules, but mine is not in the list and it does not work out of the box when I connect it to my Omnia.

The module I received is already a fs.com one with model “SFP-FE-BX”…

In this case - does it have a generic firmware? Normally this is NOT the case for provider modules. You can find out via searching fs.com for your module’s ID.
