INAGAKI Hiroshi f7f9e6bd20 ramips: use parser_trx for Buffalo WCR-1166DS 
Buffalo WCR-1166DS uses trx-fomatted firmware and the custom magic
number (0x5C436F74, "\Cot") is required for OpenWrt installation from
OEM WebUI.
But the current mtdsplit_trx doesn't support the custom magic number and
fail to parse and split to kernel and rootfs when the factory image is
flashed. Then, the kernel fails to mount rootfs automatically and panics.

Before the commit fddc78bc11, mtdsplit_trx
was patched in ramips target and the device-specific magic number was
supported only for WCR-1166DS[1].
But the patch was not inherited to the later version of the kernel and
deleted by the above commit, then, the custom magic number support was
broken.

[1]: 05d6e92594/target/linux/ramips/patches-4.4/0400-mtd-mtdsplit-add-support-for-custom-trx-magic-for-Buffalo-WCR-1166DS.patch (L27)

This patch fixes this issue by using parser_trx with specifying custom
magic number in dts instead of mtdsplit_trx.

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!

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

  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).
