From 25964ba233e474091e841a37cfb937b678ab4446 Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Fri, 31 Dec 2021 12:51:45 +0100 Subject: [PATCH] realtek: Add support for ZyXEL GS1900-48 Switch The GS1900-48 is a 48 + 2 port Gigabit L2 switch with 48 gigabit ports. Hardware: RTL8393M SoC Macronix MX25l12805D (16MB flash) 128MB RAM 6 * RTL8218B external PHY 2 * RTL8231 GPIO extenders to control the port LEDs, system LED and Reset button 2 Uplink ports are SFP cages which support 1000 Base-X mini GBIC modules. Power is supplied via a 230 volt mains connector. The board has a hard reset switch SW1, which is is not reachable from the outside. J4 provides a 12V RS232 serial connector which is connected through U8 to the 3.3V UART of the RTL8393. Conversion is done by U8, a SIPEX 3232EC. To connect to the UART, wires can be soldered to R603 (TX) and R602 (RX). Installation: Install the squashfs image via Realtek's original Web-Interface.
