Support for RTL838x based managed switches

plappermaul · 2025-03-19T18:32:34.395Z

This is closest I see https://github.com/plappermaul/realtek-doc/blob/main/RTL8261N.pdf

Do you have anything for RTL8264 too?

plappermaul · 2025-03-19T20:36:46.171Z

OpenWRT already has an offical driver for both chips in main https://git.openwrt.org/?p=openwrt/openwrt.git;a=tree;f=target/linux/generic/files/drivers/net/phy/rtl8261n;h=f714ed37d5e73d48ea2decb3c535f6fb2b847bd5;hb=refs/heads/main

Any idea of how to make use of it for ZyXEL XGS1250-12 Rev. B1?

luckylinux · 2025-03-21T16:00:36.810Z

Does anybody know if the mixed 2.5G RJ45 and 10G SFP+ such as are supported ?

ONTI ONT-S207CW-62TS
ONTI ONT-S207CW-61TS
ONTI ONT-S207CW-91TS

janh · 2025-03-22T13:48:30.745Z

The port combination and price range of the ONT-S207CW series smells like RTL837x. If that guess is correct, then OpenWrt support is impossible, because the CPU is just a 8051.

Only the ONT-S207CW-72TS is likely RTL930x: Hasivo switches - #174 by Whiterat

Borromini · 2025-03-23T12:22:04.744Z

@janh I have pulled your rt930x patches to test on my XGS1210-12 v2 with RTL8221 2,5 GbE PHYs.

The Broadcom based ones rated for 80 or 100 meters used to be very expensive, but can now be found on AliExpress for reasonable prices from a few brands.

Xicom (select the 80 m model):

aliexpress.

ZYOPM (select the 80 m model):

aliexpress.

10GBase-T SFP+ zu RJ-45 Transceiver, 10Gbe SFP+ Kupfer Ethernet CAT6a Modul,...

Smarter Shopping, Better Living! Aliexpress.com

I have personally tested the Xicom 80 m transceiver and can confirm that it reports temperature readings. It reports itself as as 10GBASE-SR fiber transceiver for compatibility reasons, and is something that seems to be standard practice. @bmork

Xicom claims that it uses the BCM84891LB in the 80 m model, and Aquantia 113C in the 30 m model.

howels · 2025-03-23T13:21:26.379Z

The ZYOPM 80m one also supports temperature and power readings. Been running it without many problems although my SFP+ modules seem to have issues with a reboot and only work properly once re-seated or swapped between slots after a reboot. Probably some hangover of the bootloader initialisation routine interfering with the driver.

blunden · 2025-03-23T13:51:44.847Z

Ok, good. When I wrote that reply, I had not read the latest posts of the thread yet so I missed that there had already been a lot of additional discussions about these different AliExpress modules.

You can try setting the link speed and duplex manually instead of relying on auto-negotiation. That solved the behaviour you describe on the stock firmware of my Hasivo RTL9301 based switch.

howels · 2025-03-23T21:34:07.917Z

I can't locate where interface speed is set in UCI, so much advice is "don't disable auto negotiation" which is fine for 1G devices with integrated phy but less helpful for 10G SFP+ devices.
Assuming this doesn't require falling back to ethtool commands?

luckylinux:

Something like this PD USB-C Female to 5.5x2.5mm Adapter ?

I wouldn't use an adapter in that sort of all-in-one formfactor, because I think it is a questionable mechanical design (too much leverage on the jack). Instead use a small "pigtail" style one with a bit of cable between the USB socket / trigger module and the barrel jack. Before such things were available as pre-built adapters, I used PD trigger modules from WeAct Studio - https://www.aliexpress.com/item/1005003336833794.html and just cut+soldered on the original cable from whatever power supply I didn't trust (with a bit of large size heatshrink tube around the PCB).

Alternatively 12v with 5.5 x 2.1 is a pretty common standard AC->DC adapter size, so you might be able to find a good brand name one in your local e-waste bin ;-).

For general diagnosing of PD stuff (e.g. listing what voltages and currents a power supply reports) as well as a very accurate voltage and current meter (using a Texas Instruments measurement IC), and bluetooth+USB data logging of voltage/current/power etc., I recommend the Ruideng TC66C (TC66 is the non-bluetooth version) - https://www.aliexpress.com/item/32968303350.html beware knock-offs sold elsewhere, both WeAct and Ruideng are trustworthy manufacturers and sell directly. For the TC66C, the YT channel TheHWcave has a great tutorial as well as pointers to open source logging software.

luckylinux · 2025-03-24T18:49:07.412Z

I already bought them (both the "questionable" Adapter as well as the Cables e.g. https://www.aliexpress.com/item/1005006018729093.html and https://www.aliexpress.com/item/1005006058252700.html).

Not sure what you mean exactly by "Leverage". Do you mean a "Loose Fit" or a Lack of Strain Relief rather ?

It was also not very clear if it was 5.5x2.5mm or 5.5x2.1mm so I bought both of them again ...

For the TC66C, did you give me the link to the Official Store ? RD = Ruideng ?

Should I also get the HD35 Electronic Load or no need for that ?

Borromini · 2025-03-24T20:20:51.552Z

@janh I have no baseline here, since last OpenWrt build I tried was main with 5.15 and olliver's patches for the XGS1210-12, slightly adapted for my B1 revision. But that did boot. I assume your tree is still booting for you on your XGS1010-12? I have pulled these commits into my tree, on top of main:

064cd9c7d4 realtek: add support for 10GBase-LR
762c1c3580 realtek: enable 2500Base-X interface mode
d2a45732c7 realtek: consider auto-negotiation state in rtl8226_set_eee
e36adccd08 realtek: improve RTL8226 support
91852fd7c2 realtek: call rtl9300_serdes_setup for additional PHY interface modes
a4f4363618 realtek: fix HSGMII PHY mode
f6e2a1a5e6 realtek: refactor RTL930x MAC config to fix PHY ports

Then a basic patch on top for the XGS1210-12 support:

https://dpaste.com/292V9SNNK.txt

I'm addressing this question to anyone knowledgeable of course. The 5.15 log would show the device booting through all the way to a prompt, but the 6.6 boot hangs here:

[    0.773224] Probing RTL838X eth device pdev: 820a8400, dev: 820a8410
[    0.799573] Found SoC ID: 9302: RTL9302B, family 9300

I noticed the 5.15 log would show a different identifier (?) for the 'eth device pdev', not sure if that's relevant?

[    0.519562] Probing RTL838X eth device pdev: 82085a00, dev: 82085a10
[    0.546175] Found SoC ID: 9302: RTL9302B, family 9300

It looks like what could be a PCI ID, but I'm not sure it actually is something like that.

For adapters which are "all in one" i.e. are rigid and incorporate both the USB type C socket, and also the the barrel jack plug, then the rigid part acts as a lever so that small movements in the cable get translated into large turning forces in the jack plug, so can easily damage both the jack plug and the jack socket. For the TC66C (not essential, but a useful bit of kit for your toolbox), the HD35 is useful if you want to test the performance of USB power supplies (e.g. AC adapters or power banks - particularly with power banks it's useful to measure actual vs. claimed capacity in conjunction with the TC66C). "RD" is the official store, their western friendly name is "RD Tech".
As you said - many supplies don't support 12v - a lot of supplies intended for phones are 5v and 9v only, and many laptop supplies also skip 12v e.g. a Dell USB-PD supply that I have here does 5v, 18v, 20v only. The attached shows powering an access point with a PD trigger to barrel jack adapter, with the TC66 showing instantaneous voltage+power and cumulative energy. The third white USB cable is optional and can be used for non-BLE data logging and to power the TC66C independently of the supply under test.

I think it's too late now to get the TC66C for this Test. It would take at least a couple extra Weeks to arrive here.

I bought some DC Jack to Terminal Blocks Adapters which should be sufficient to test with a DC Multimeter, just to make sure I got the right Voltage.

Or, worst Case, I can plug that into an Oscilloscope with a Differential Voltage Probe.

USB PD 12V is unfortunately not a long term solution. For some reason the 12V option was dropped from rev2 of the USB PD spec so it's only mandated for rev1 chargers. Chargers supplying 12V will become scarcer in favour of 5V, 9V, 15V and 20V.

On another Subject, are there known 25gbps Switches working / soon working with OpenWRT ?

Something like (but cheaper):

Mikrotik CRS504-4XQ-IN - 4 x QSFP28 (4 x 100gbps) also breakable into 16xSFP28 (16 x 25gbps)
Mikrotik CRS518-16XS-2XQ-RM - 2 x QSFP28 (2 x 100gbps) + 16 x SFP28 (16 x 25gbps)
Mikrotik CRS510-8XS-2XQ-IN - 2 x QSFP28 (2 x 100gbps) + 8 x SFP28 (8 x 25gbps)
Probably overkill ... Mikrotik CRS520-4XS-16XQ-RM - 16 x QSFP28 (16 x 100gbps) + 4 x SFP28 (4 x 25gbps)

RTL83xx/RTL93xx are the only dedicated switch platforms supported by OpenWrt. Those switches you link to, supportability depends on their internals. With QSFP and the likes I think you're looking at Broadcom/Marvell and the likes.
