Andreas Böhler 6ee3f80efb realtek: add support for XikeStor SKS7300-4X4T
The XikeStor SKS7300-4X4T is a 10GbE switch with 4x copper ports and
4x SFP slots. It has a built-in console port and is powered by a RTL9303
SoC.

Specifications:
---------------

  * Soc: RTL9303
  * Flash: 32 MiB SPI flash
  * RAM: 512 MiB
  * Ethernet: 8x 10/100/1000/2500/5000/10000 Mbps
  * Buttons: 1x Reset
  * UART: CISCO console ports on the front, 115200, 8n1
  * controllable fan, integrated temperature sensor

Not yet enabled:
----------------
  * Fan control: it's controlled via simple i2c registers, but no driver
                 has been written yet.

Installation:
-------------

This device uses an obfuscated bootloader and an obfuscated image. As such,
the installation can only be performed using the console ports.

1. Set the switch to boot from the first image.

2. Attach console cable and hold Ctrl+C while powering on the switch

3. After a few seconds, a very basic U-Boot menu appears. Wait for the user
   input to appear, then press "z" to get to the message "Please input auth
   code".

4. Type "jiangks" as the password, the RTL9300 prompt appears.

5. Load the OpenWrt initramfs image via TFTP:

   > setenv serverip 192.168.0.1
   > setenv ipaddr 192.168.0.2
   > tftpboot 0x83000000 openwrt.bin
   > bootm 0x83000000

6. Once OpenWrt has booted, use the "sysupgrade" image to perform the
   actual installation.

7. Reboot the switch and enjoy OpenWrt.

Recovery/return to stock:
-------------------------

Flash an OEM firmware upgrade file via sysupgrade.

OpenWrt logo

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Sunshine!

Download

Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.

If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.

An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:

Development

To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.

Requirements

You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. Run make to build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

The main repository uses multiple sub-repositories to manage packages of different categories. All packages are installed via the OpenWrt package manager called opkg. If you're looking to develop the web interface or port packages to OpenWrt, please find the fitting repository below.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
