New BCM4908 family based routers will use U-Boot bootloader. That will require using a totally different firmware format. Kernel has to be put in a FIT image. OpenWrt has some helpers for generating .its files but they don't fit BCM4908 requirements and there is no simple way of extending any of them. The best solution seems to be storing an .its template. BCM4908 bootfs may: 1. contain extra binaries (other than kernel & DTB) 2. include multiple DTB files 3. store device specific U-Boot configurations with custom properties Such setups are too complex to generate using shell script. Raw .its file on the other hand seems quire clean & reasonable. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> (cherry picked from commit a02c971dff934a11ddadf7ffd850dabcab5a3cdf)
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.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync 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.
