Hank Moretti 54dc1cde48 mediatek: filogic: add support for Xiaomi WR30U 
Hardware specification:
  SoC: MediaTek MT7981B 2x A53
  Flash: ESMT F50L1G41LB 128MB
  RAM: NT52B128M16JR-FL 256MB
  Ethernet: 4x 10/100/1000 Mbps
  Switch: MediaTek MT7531AE
  WiFi: MediaTek MT7976C
  Button: Reset, Mesh
  Power: DC 12V 1A

Flash instructions:

1. Get ssh access
   Check this link: https://forum.openwrt.org/t/openwrt-support-for-xiaomi-ax3000ne/153769/22

2. Backup import partitions
   ```
   dev:    size   erasesize  name
   mtd1: 00100000 00020000 "BL2"
   mtd2: 00040000 00020000 "Nvram"
   mtd3: 00040000 00020000 "Bdata"
   mtd4: 00200000 00020000 "Factory"
   mtd5: 00200000 00020000 "FIP"
   mtd8: 02200000 00020000 "ubi"
   mtd9: 02200000 00020000 "ubi1"
   mtd12: 00040000 00020000 "KF"

   ```

   Use these commands blow to backup your stock partitions.
   ```
   nanddump -f /tmp/BL2.bin /dev/mtd1
   nanddump -f /tmp/Nvram.bin /dev/mtd2
   nanddump -f /tmp/Bdata.bin /dev/mtd3
   nanddump -f /tmp/Factory.bin /dev/mtd4
   nanddump -f /tmp/FIP.bin /dev/mtd5
   nanddump -f /tmp/ubi.bin /dev/mtd8
   nanddump -f /tmp/KF.bin /dev/mtd12
   ```
   Then, transfer them to your computer via scp, netcat, tftp
   or others and keep them in a safe place.

3. Setup Nvram
   Get the current stock: `cat /proc/cmdline`

   If you find `firmware=0` or `mtd=ubi`, use these commands:
   ```
   nvram set boot_wait=on
   nvram set uart_en=1
   nvram set flag_boot_rootfs=1
   nvram set flag_last_success=1
   nvram set flag_boot_success=1
   nvram set flag_try_sys1_failed=0
   nvram set flag_try_sys2_failed=0
   nvram commit
   ```

   If you find `firmware=1` or `mtd=ubi1`, use these commands:
   ```
   nvram set boot_wait=on
   nvram set uart_en=1
   nvram set flag_boot_rootfs=0
   nvram set flag_last_success=0
   nvram set flag_boot_success=1
   nvram set flag_try_sys1_failed=0
   nvram set flag_try_sys2_failed=0
   nvram commit
   ```

4. Flash stock-initramfs-factory.ubi
   If you find `firmware=0` or `mtd=ubi`:
   `ubiformat /dev/mtd9 -y -f /tmp/stock-initramfs-factory.ubi`

   If you find `firmware=1` or `mtd=ubi1`:
   `ubiformat /dev/mtd8 -y -f /tmp/stock-initramfs-factory.ubi`

   Then reboot your router, it should boot to the openwrt
   initramfs system now.

5. Setup uboot-env
   Now it will be setup automatically in upgrade process,
   you can skip this step.

   If your `fw_setenv` did not work, you need run this command:
   `echo "/dev/mtd1 0x0 0x10000 0x20000" > /etc/fw_env.config`

   Then setup uboot-env:
   ```
   fw_setenv boot_wait on
   fw_setenv uart_en 1
   fw_setenv flag_boot_rootfs 0
   fw_setenv flag_last_success 1
   fw_setenv flag_boot_success 1
   fw_setenv flag_try_sys1_failed 8
   fw_setenv flag_try_sys2_failed 8
   fw_setenv mtdparts "nmbm0:1024k(bl2),256k(Nvram),256k(Bdata),
   2048k(factory),2048k(fip),256k(crash),256k(crash_log),
   34816k(ubi),34816k(ubi1),32768k(overlay),12288k(data),256k(KF)"
   ```

6. Flash stock-squashfs-sysupgrade.bin
   Use shell command:
   `sysupgrade -n /tmp/stock-squashfs-sysupgrade.bin`
   Or go to luci web.

If you need to change to Openwrt U-Boot layout, do next. If you
do not need, please ignore it.

Change to OpenWrt U-Boot:

1. Flash ubootmod-initramfs-factory.ubi
   Check mtd partitions: `cat /proc/mtd`
   ```
   mtd7: 00040000 00020000 "KF"
   mtd8: 02200000 00020000 "ubi_kernel"
   mtd9: 04e00000 00020000 "ubi"
   ```

   Run following command:
   `ubiformat /dev/mtd8 -y -f /tmp/ubootmod-initramfs-factory.ubi`
   Then reboot your router, it should boot to the openwrt initramfs
   system now.

2. Check mtd again
   ```
   mtd7: 00040000 00020000 "KF"
   mtd8: 07000000 00020000 "ubi"
   ```
   Make sure mtd8 is ubi.

3. Install kmod-mtd-rw
   Run command: `opkg update && opkg install kmod-mtd-rw`
   Or get it in openwrt server, or build it yourself, then install
   it manually

   Then run this command:
   `insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`

4. Clean up pstore
   Run Command: `rm -f /sys/fs/pstore/*`

5. Format ubi and create new ubootenv volume
   ```
   ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
   ubimkvol /dev/ubi0 -n 0 -N ubootenv -s 128KiB
   ubimkvol /dev/ubi0 -n 1 -N ubootenv2 -s 128KiB
   ```

6. (Optional) Add recovery boot feature.
   ```
   ubimkvol /dev/ubi0 -n 2 -N recovery -s 10MiB
   ubiupdatevol /dev/ubi0_2 /tmp/ubootmod-initramfs-recovery.itb
   ```

7. Flash Openwrt U-Boot
   ```
   mtd write /tmp/ubootmod-preloader.bin BL2
   mtd write /tmp/ubootmod-bl31-uboot.fip FIP
   ```

6. Flash ubootmod-squashfs-sysupgrade.itb
   Use shell command:
   `sysupgrade -n /tmp/ubootmod-squashfs-sysupgrade.itb`
   Or go to luci web.

Now everything is done, Enjoy!

Go Back to stock from Openwrt U-Boot:

1. Force flash ubootmod-initramfs-recovery.itb
   Use shell command:
   `sysupgrade -F -n /tmp/ubootmod-initramfs-recovery.itb`
   Or go to luci web.
   Then it should boot to the openwrt initramfs system now.

2. Format ubi and Nvram
   ```
   ubidetach -p /dev/mtd8; ubiformat /dev/mtd8 -y; ubiattach -p /dev/mtd8
   mtd erase Nvram
   ```

3. Install kmod-mtd-rw
   Run command: `opkg update && opkg install kmod-mtd-rw`
   Or get it in openwrt server, or build it yourself, then install
   it manually

   Then run this command:
   `insmod /lib/modules/$(uname -r)/mtd-rw.ko i_want_a_brick=1`

4. Flash stock U-Boot and ubi
   ```
   mtd write /tmp/BL2.bin BL2
   mtd write /tmp/FIP.bin FIP
   mtd write /tmp/ubi.bin ubi
   ```
   Then reboot your router, waiting it finished rollback in minutes.

Go Back to stock from stock layout Openwrt:
   Just run command: `ubiformat /dev/mtd8 -y -f /tmp/ubi.bin`
   Then reboot your router, waiting it finished rollback in minutes.

Notes:
1. Openwrt U-Boot and ubootmod openwrt did not enable NMBM.
   Please make your backup safe.

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 python3.7+ 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).
