# RTLPlayground
A Playground for Firmware development for RTL8372/RTL8373 based 2.5GBit Switches.
It provides a minimal alternative firmware for the unmanaged switches. At this point,
For each hardware configuration of these devices, there is usually a managed and an
umanaged version sold, with mostly identical hardware. The aim is to provide management
features also for unmanaged devices with additional features such as Management VLAN,
dhcp servers, multi-language support, IPv6 and TLS-encrypted web-pages.
The playground currently provides a minimal alternative firmware for both the managed and unmanaged switches.
When used with unmanaged switches, it will provide some management features such as
setting up VLANs, mirroring ports and provide a Web-Server (currently no functions,
really), but will need to be configured via a serial connection. Installation on
managed devices only makes sense for developers, as plenty of features of the managed
switches are not supported, yet.
At this point,
the firmware can be installed on the hardware as given below, how much of the switch
will actually work as a switch, will vary. On the

To do meaningful debugging you will need to use a serial console, so soldering skills
are required. Flashing must be done via a SOIC-8 PatchClamp or by soldering a socket
