# 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,
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

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.
On the 4-Port Ethernet + 2 Port SFP+ devices, one of the SFP+ ports will not work.

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

UPDATE: The Code comes with a port of the [uIP](https://github.com/adamdunkels/uip)
TCP/IP stack and includes a minimal web-server that can be used to work with the switch,
so if you use a patch-clamp for updating the firmware (~3 USD/EUR), you can try this
out without the need to solder anything. See the instructions below.
Note that updating the firmware of a managed switch with the images created in this
project will not work, because it is currently unknown how to generate the require
checksum, see this
[issue](https://github.com/up-n-atom/SWTG118AS/issues/4).
If you don't want to open your device, you can use the project's code to learn about the
devices by looking at the image using e.g. Ghidra.
