# RTLPlayground # RTLPlayground
A Playground for Firmware development for RTL8372/RTL8373 based 2.5GBit Switches 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,
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
keepLINK kp-9000-6hx-x (RTL8372 + RTL8221B 2.5GBit PHY: 5 x 2.5GBit + 1x 10GBit SFP+),
at present the system will provide switching capabilities between the 5 Ethernet ports.
The ports served by the RTL8372 will be 1G/2.5G auto-detect. Port 5 connected via the
RTL8221B, will only work in 2.5GBit mode. All configuration must be done via serial
connection (there is no web-interface), so soldering skills are required. Flashing
must be done via a SOIC-8 PatchClamp or by soldering a socket for the flash chip.
The SFP+ port does not work. There is no access to the CPU-port (NIC).
If you don't want to solder, you can use this to learn about the devices by looking at
the image using e.g. Ghidra.
