Installation
------------
OEM upgrade method:
* Log in to OEM management web interface
* Navigate to Maintenance > Firmware > Management
* If "Active Image" has the first option selected, OpenWrt will need to be
flashed to the "Active" partition. If the second option is selected,
OpenWrt will need to be flashed to the "Backup" partition.
* Navigate to Maintenance > Firmware > Upload
* Upload the openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin
file by your preferred method to the previously determined partition.
When prompted, select to boot from the newly flashed image, and reboot
the switch.
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin
U-Boot TFTP method:
* Configure your client with a static 192.168.1.x IP (e.g. 192.168.1.10).
* Set up a TFTP server on your client and make it serve the initramfs
image.
* Connect serial, power up the switch, interrupt U-boot by hitting the
space bar, and enable the network:
> rtk network on
> Since the GS1900-24 v1 is a dual-partition device, you want to keep the
OEM firmware on the backup partition for the time being. OpenWrt can
only be installed in the first partition anyway (hardcoded in the
DTS). To ensure we are set to boot from the first partition, issue the
following commands:
> setsys bootpartition 0
> savesys
* Download the image onto the device and boot from it:
> tftpboot 0x81f00000 192.168.1.10:openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-initramfs-kernel.bin
> bootm
* Once OpenWrt has booted, scp the sysupgrade image to /tmp and flash it:
> sysupgrade /tmp/openwrt-realtek-rtl838x-zyxel_gs1900-24-v1-squashfs-sysupgrade.bin

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!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX 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 python3.6+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo 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.
