Damien Dejean 94607d6285 realtek: add support for Zyxel XMG1915-10E 
The XMG1915-10E is a switch with 8 copper ports and 2 SFP+ cages.

Specifications:
---------------
  * SoC: RTL9302C
  * Flash: 32 MiB SPI NOR flash
  * RAM: 256 MiB
  * Ethernet: 8x 10/100/1000/2500 Mbps (RTL8224)
  * SFP: 2x SFP+ cages
  * UART: 1x 4 pins serial header, 115200 bauds, 8n1, 3.3v logic levels,
          pinout: unused (top), TX, RX, GND (bottom)
  * Buttons: 1x "Reset" button

Works:
------
  - 2 SFP+ cages either 1G/10G or 2.5G
  - 8*2.5G Ethernet ports
  - Switch function
  - LEDs
  - Boot from flash
  - Assigning MAC addresses from flash

Ethernet ports:
---------------
The 8x 2.5Gbps ethernet ports are provided by two RTL8224 chips. The
ports are supported by the upstream realtek PHY driver plus a local
initialization patch for the 10g-qxgmii mode.

Installation:
-------------
This device uses ZyNOS instead of Linux which makes the installation a
bit cumbersome. OpenWRT will be installed on the slot of the second
firmware image, thus the switch original firmware can be booted with a
little change. The serial console is required.

1. Set the switch to boot from the first image. This is required to
   be sure not to be blocked in the middle of the installation
   procedure.

2. Connect to the switch using the serial adapter and interrupt the boot
   process by pressing "Enter" repeatedly.

3. Load the OpenWRT initramfs image using xmodem. From bootext console
   (use ATHE to get the list of commands):

   > ATUP 81800000,file_length
   > ATGO 81800000

4. Wait for OpenWRT to boot, once this is done transfer the loader
   binary and the sysupgrade image to /tmp using scp.

5. Install OpenWRT permanently by writing the images on the flash:

  > mtd write /tmp/loader.bin loader
  > mtd write /tmp/sysupgrade.bin firmware

6. Reboot the switch and from the stock firmware set the configuration
   to boot from the second image (Maintenance > Firmware upgrade > Boot
   image).

7. Reboot again and enjoy OpenWRT.

Recovery/Return to stock:
-------------------------
1. Connect the switch using the serial adapter and interrupt the boot
   process during the "DRAM POST: Testing:" sequence by pressing '$'
   until the "XMG1915$" prompt appears.

2. Start an ymodem upgrade using the following command and use an xmodem
   upload tool to send the .bin file provided in an OEM upgrade package.

   XMG1915$ upgradeY image2 81000000 115200
   ## Ready for binary (ymodem) download to 0x081000000 at 115200 bps...

3. Wait for the upgrade process to finish and reboot the switch.

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).
