Furong Xu 1613e3340b uboot-mediatek: add support for Xiaomi Redmi Router AX6000 
U-Boot flash instructions:

0. OpenWrt U-Boot does not support stock layout, it comes with recovery
boot support, automatic tftp recovery and never blocks UART.

A new flash layout is introduced, we call it OpenWrt U-Boot layout,
stock flash layout and the old OpenWrt layout are not supported.

During the whole flash procedure, please do not reboot or power off
unless requested explicitly, or you will break your device.

1. Your device should already running OpenWrt.
If not, follow the instructions to flash OpenWrt:
https://github.com/openwrt/openwrt/pull/11115

2. Backup BL2 Nvram Bdata Factory and FIP in case you break something or
in case you want to go back to stock firmware one day.

cat /dev/mtdblock0 > /tmp/BL2.bin
cat /dev/mtdblock1 > /tmp/Nvram.bin
cat /dev/mtdblock2 > /tmp/Bdata.bin
cat /dev/mtdblock3 > /tmp/Factory.bin
cat /dev/mtdblock4 > /tmp/FIP.bin

And save all whose bin files to somewhere safe.

Then backup your configurations, since ubiformat for entire mtd device is
required to create new ubootenv volume for OpenWrt U-Boot.

3. Run the following cmd to boot into an initramfs with the new OpenWrt
U-Boot layout that expand ubi partion to the end of flash:

ubiformat /dev/mtd7 -y -f /tmp/ax6000-ubootmod-initramfs-factory.ubi

4. After boot into initramfs, check mtd partion info.
The ubi partion should be mtd5

root@OpenWrt:~# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00100000 00020000 BL2
mtd1: 00040000 00020000 Nvram
mtd2: 00040000 00020000 Bdata
mtd3: 00200000 00020000 Factory
mtd4: 00200000 00020000 FIP
mtd5: 07a80000 00020000 ubi

5. Load kmod-mtd-rw to temporarily make the bootloader partions writable.
The kmod-mtd-rw is from the feeds, it is not packed in initramfs-factory
by default.

To install kmod-mtd-rw via opkg:

opkg update && opkg install kmod-mtd-rw

Or, download kmod-mtd-rw.ipk from OpenWrt server and install it manually
e.g:
https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/kmods/
Select your OpenWrt release version and kernel version accordingly.

Load kmod-mtd-rw:
insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1

6. Run the following cmd to clean all pending crash dumps in pstore,
or OpenWrt U-Boot may boot into NAND recovery or tftp recovery.

rm -f /sys/fs/pstore/*

7. Format ubi and create new ubootenv volume:

ubidetach -p /dev/mtd5; ubiformat /dev/mtd5 -y; ubiattach -p /dev/mtd5
ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB

8. This is optional. Skip this if you do not want to have NAND recovery
boot feature offered by OpenWrt U-Boot. Don't worry, you always have
automatic tftp recovery feature enabled.

ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
ubiupdatevol /dev/ubi0_2 /tmp/ax6000-ubootmod-initramfs-recovery.itb

9. Now, flash new U-Boot. Bye-bye ugly stock U-Boot.

mtd write /tmp/ax6000-ubootmod-preloader.bin BL2
mtd write /tmp/ax6000-ubootmod-bl31-uboot.fip FIP

10. Flash the squashfs-sysupgrade.bin as usual:

sysupgrade -n /tmp/ax6000-ubootmod-squashfs-sysupgrade.itb

Enjoy!

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).
