The kernel support necessary to use a console keyboard was not built on x86, affecting real and virtual machines alike. The console keyboard would function properly in GRUB, but would not work at all once Linux booted. It appeared that the console was intended to work because console video appeared on the display, including prompts to enter failsafe or select the debug log level from the keyboard, and the prompt to "Press Enter to activate this console", but there was no way to provide input to it. All keystrokes were ignored. This enables several kernel configuration options to enable HID and USB HID support (CONFIG_HID, CONFIG_HID_SUPPORT, CONFIG_HID_GENERIC, and CONFIG_USB_HID), making the keyboard functional. For alignment with armsr, CONFIG_USB_HIDDEV is also added, although not strictly necessary for keyboard support. Note that this change also causes CONFIG_HID_HYPERV_MOUSE to be enabled for x86/64 and x86/generic: it was already set in these subarchitectures' kernel configurations, but was ineffective due to CONFIG_HID being absent. The omission of keyboard support on x86 may not have been widely noticed because USB HID is not used on production OpenWrt x86 machines such as pc-engines,apu2 which only have a serial console, or with the default x86 configuration used by scripts/qemustart, which uses -nographic and does not configure a virtual physical console but instead uses a serial console. This configuration change results in, for x86_64, +40kB in kernel.bin and just over +40kB in gzip-compressed "combined" images. This should not be a problem for the non-storage-constrained x86 target. Until 2a86425de107, CONFIG_HID, CONFIG_USB_HID, and CONFIG_USB_HIDDEV were set in the target-level kernel configuration, and CONFIG_HID_GENERIC was set at the subtarget level. These are reintroduced strictly at the subtarget level by request. This applies to the 64, generic, and legacy subtargets, omitting geode.

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.

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
-
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.
