SL-SG008W Sodola

Curious if this dirt cheap switch has OpenWRT support.

Realtek based. Metal case. Workable switch.

Weirdly short lead on the AC side of power supply, 9 inches (23cm). The DC side cord is 45 inches (114cm). Switch Weighs 266g (9.4 oz). It has a red power LED with blue LED port indicators. They are under the ports. The power LED is very close to the port 1 indicator. The web interface on this is very similar to TP-Link's TL-SG108E (compare screenshots in the two manuals). I think they might even use the same chip as the feature sets are also quite similar. The feature set seems complete, and the web interface is reasonable to get around. == Internals == This switch is a single chip switch solution with four NT36201D magnetics packages. The switch chip is a QFP-128 package, has a 25MHz crystal oscillator, and is supplied with 3.3V and 1.1V supplies. It uses an external flash chip to store the firmware. The chip has a heatsink, but it also has a thermal pad connecting it to the case behind the circuit board. Doesn't seem to need this much cooling, but it could be good in hot locations. There is a internal 3-pin unpopulated serial header. It operates at 57600 baud. You can interrupt the boot to access an SPI flash viewer, or to download a new kernel (unknown method). After booting, the switch provides a basic configuration menu. From here you can print the IP/Subnet/Gateway/MAC. You can modify the MAC, Model Name, Hardware Version, and change the factory default IP configuration. I dumped parts of the flash, and I did see the string "RTL8367N" in the flash dump. I couldn't find direct info about this chip, but there is also RTL8370N which seems very close and a datasheet is available if you need details.

Also I've seen someone modify a build somehow to get the RTL8361 going so while I'm sure it is possible.

When I search for it there is no information that comes up. This thing is very low budget it doesn't seem like a radical proposition that it could be made to function via OpenWRT.

IDK not entirely sure here but it is curious.





No, this device is not supported.

You can always check for support by visiting the firmware selector.

As asked could it be made to function with it?
I guess my real question is it impossible to support at the end of the day?
Is it a hardware issue where it "Can Not Be Supported" or that no one simply has taken the liberty to build something for it?

The rtl838x chipsets do have support in OpenWrt. I don't know about the rtl836x series.

Assuming that the Realtek chipset can be or is now supported, the next question is how much RAM and flash storage is onboard. The device would need to have 16MB minimum for flash storage, and 128MB of RAM (8MB flash + 64MB RAM is supported in 24.10, but this is expected to increase to 16/128 in future versions; it's unlikely that anyone would put in development efforts for a device that won't be compatible past 24.10).

Certainly this would apply, even if the device can be supported at the technical level. That's where you come in -- you have the device in hand and can begin the discovery and potential development efforts.

After some digging I discovered it is the RTL8370N for certain.

The RTL8370N Ethernet switch chip typically features a 16KB (16kbit) RAM and a 1024KB (1MB) Flash memory size. However, some implementations may use external RAM and Flash, such as 1Gb RAM and 128Mb Flash in some Wireless Access Gateways.

I am unsure what they include at the moment
