Shiji Yang c7059c56a8 ath79: improve support for Letv LBA-047-CH 
1. Convert wireless calibration data to NVMEM.
2. Enable control green status LED and change default LED behaviors.
   The three LEDs of LBA-047-CH are in the same position, and the green
   LED will be completely covered by the other two LEDs. So don's use
   green LED as WAN indicator to ensure that only one LED is on at a time.
   LED     Factory          OpenWrt
   blue    internet fail    failsafe && upgrade
   green   internet okay    run
   red     boot             boot
3. Reduce the SPI clock to 30 MHz because the ath79 target does not
   support 50 MHz SPI operation well. Keep the fast-read support to
   ensure the spi-mem feature (b3f9842330) is enabled.
4. Remove unused package "uboot-envtools".
5. Split the factory image into two parts: rootfs and kernel.
   This change can reduce the factory image size and allow users to
   upgrade the OpenWrt kernel loader uImage (OKLI) independently.

   The new installation method: First, rename "squashfs-kernel.bin" to
   "openwrt-ar71xx-generic-ap147-16M-kernel.bin" and rename "rootfs.bin"
   to "openwrt-ar71xx-generic-ap147-16M-rootfs-squashfs.bin". Then we
   can press reset button for about 5 seconds to enter tftp download mode.
   Finally, set IP address to 192.168.67.100 and upload the above two
   parts via tftp server.

Tested on Letv LBA-047-CH

README.md

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!

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 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).
