After applying the patches in this directory to the OpenWrt Build you can generate an image by doing the following:
Use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware.
For WRT1900AC: The "Target System" in make menuconfig should be set to "Marvell Armada XP/370"
The "Subtarget" in make menuconfig should be set to "Mamba"
In "Target Images" in make menuconfig you should enable "jffs2"
You need to have installed gcc, binutils, bzip2, flex, python, perl make, find, grep, diff, unzip, gawk, getopt, libz-dev and libc headers.
Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively
Run "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/.
Use "make menuconfig" to configure your image.
Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications.
After the build completes the firmware image for the WRT1900AC will be located at: ./bin/mvebu/openwrt-mvebu-mamba-jffs2-128k.img
How to update from Belkin/Linksys UI
Login into WRT1900AC local UI
Navigate to the Connectivity tab
Select Manual firmware update
Select image to load (e.g., openwrt-armadaxp--jffs2-128k.img)
Select Update firmware
After the firmware is updated, the unit will reboot, and the default ip address will be 192.168.200.1
The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it.
To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system.
