Jonas Jelonek 81b148fd38 realtek: add support for XikeStor SKS8300-12X V1 
Hardware:
  - SoC: RTL9313
  - Memory: 512MB
  - Flash: SPI-NOR 32MB (GigaDevice GD25Q256EFIR)
  - Ethernet: 12x 1/2.5/10 Gbps (SFP+)
  - LED/Keys (GPIO): 1x/1x
  - UART: "Console" port on the front panel
    - type: RS-232C
    - connector: RJ-45
    - settings: 9600n8 / 115200n8
  - Watchdog: Diodes PT7A7514WE
  - Monitoring: LM75A
  - Power: 100-240 VAC 50/60 Hz C13/C14

Important notes:
---------------

* the device uses 9600 Baud by default but this extremely slows down the
  device when using the serial console. OpenWrt is configured to use
  115200 Baud. If you need to enter the bootloader, you need to use 9600
  Baud.

* PT7A7514WE watchdog is fed through hardware-assisted SYS_LED. However,
  the bootloader seems to deactivate that again during autoboot. There's
  a quirk in early arch setup for this.

* a kernel binary "nos.img" needs to be stored into JFFS2 filesystem
  using 4KiB erase block instead of 64KiB.

* V1 is the version with the 19"-sized case. As of 2026, there's a newer
  version with a narrow case.

Flash instructions using initramfs image:
-----------------------------------------

(mostly taken from 0dc0b98295)

 1. Prepare TFTP server with an IP address in 192.168.2.0/24.
 2. Connect your PC to Port 1 on SKS8300-12X.
 3. Power on SKS8300-12X and interrupt autoboot by Ctrl + B.
 4. Login to the vendor CLI by Ctrl + F and "diagshell_unipoe_env" as password.
 5. Switch baudrate to 115200 by running a command and then reconnect
    with different settings:

    baudrate 115200

 6. Switch to U-Boot CLI by "debug_unish_env".
 7. Enable Port 1 with the following commands:

    rtk 10g 0 fiber1g	# (or fiber10g if 10GBase-*R)
    rtk ext-devInit 0	# init RTL8231 that holds SFP GPIOs
    rtk ext-pinSet 2 0	# set tx-disable of port 1 to LOW

 8. Transfer initramfs image via TFTP and boot it:

    tftpboot 0x82000000 <serverip>:<image name>
    bootm 0x82000000

 9. On the initramfs image, backup the stock firmware if needed.
10. Upload (or download) sysupgrade image to the device.
11. Erase "firmware" partition to cleanup JFFS2 of stock FW:

    mtd erase firmware

12. Perform sysupgrade with the sysupgrade image.
13. Wait until the flash completes and the system reboots into OpenWrt.

Reverting to stock firmware:
----------------------------

(taken from 0dc0b98295)

1. Prepare OpenWrt SDK to use the mkfs.jffs2 tool contained in it

   Note: the official mkfs.jffs2 tool in mtd-utils doesn't support 4KiB
         erase size and not usable for SKS8300-8X

2. Create a directory for working
3. Download official firmware for SKS8300-8X from XikeStor's official
   website
4. Rename the downloaded firmware to "nos.img" and place it to the
   working directory
5. Create a JFFS2 filesystem binary with the working directory

   /path/to/mkfs.jffs2 -p -b -U -v -e 4KiB -x lzma \
       -o nos.img.jffs2 -d /path/to/working/dir/

6. Upload the created JFFS2 filesystem binary to the device
7. Erase the "firmware" partition

   mtd erase firmware

8. Write the JFFS2 filesystem binary to the "firmware" partition

   mtd write /path/to/nos.img.jffs2 firmware

9. After writing, reboot the device by power cycle

README.md

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.

Related Repositories

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).
