So flash requires modifying the uboot variable `boot_from=ubi` to ensure that it only starts from Ubi. - The Product and Custom partitions are original and only exist to align with the original layout; they are not used by OpenWrt. - id: 0, kernel - id: 1, rootfs - id: 2, rootfs_data - **USB-to-TTL Serial Adapter** (e.g., CH340 or CP2102). - **Dupont Wires** (male-to-male, 3 wires). - **PC/Laptop** with a serial communication tool. - Screwdriver (to open the router case). 1. **OpenWrt Firmware**: - Download the appropriate `wr3000k-<build_time>-mediatek-filogic-tenbay_wr3000k-squashfs-sysupgrade.bin` firmware file for your router from the [OpenWrt website](https://openwrt.org/). 2. **Serial Communication Tool**: - Windows: PuTTY, Tera Term. - Linux/Mac: Minicom, screen. 3. (Optional) **TFTP Server**: - Install a TFTP server like Tftpd64 or tftp-hpa. --- 1. Open the router casing and locate the **TX, RX, and GND** pins. 2. Connect the router pins to the USB-to-TTL adapter as follows: - **TX (router)** → **RX (adapter)** - **RX (router)** → **TX (adapter)** - **GND (router)** → **GND (adapter)** 3. Do **not** connect the VCC pin to avoid damage. - **Baud rate**: 115200 - **Data bits**: 8 - **Stop bits**: 1 - **Parity**: None - **Flow control**: None --- 1. Power on the router and observe the serial terminal output. 2. When prompted (e.g., `Hit any key to stop autoboot: 3`), press the '/' key quickly to interrupt the boot process. 3. You will see the U-Boot Boot Menu: ```plaintext *** U-Boot Boot Menu *** 1. Factory mode 2. Startup system (Default) 3. Upgrade firmware 4. Upgrade ATF BL2 5. Upgrade ATF FIP 6. Upgrade single image 7. Load image 0. U-Boot console Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit ``` 4. Select Option 0 by typing 0 and pressing Enter. 5. Input into ```plaintext MT7981> setenv boot_from ubi MT7981> saveenv Saving Environment to MTD... Erasing on MTD device 'nmbm0'... OK Writing to MTD device 'nmbm0'... OK OK MT7981> printenv baudrate=115200 boot_from=ubi ... ``` the above indicates system will start from *ubi*. and then type ```plaintext MT7981> reset ``` will boot from *ubi* 1. Power on the router and observe the serial terminal output. 2. When prompted (e.g., `Hit any key to stop autoboot: 3`), press the '/' key quickly to interrupt the boot process. 3. You will see the U-Boot Boot Menu: ```plaintext *** U-Boot Boot Menu *** 1. Factory mode 2. Startup system (Default) 3. Upgrade firmware 4. Upgrade ATF BL2 5. Upgrade ATF FIP 6. Upgrade single image 7. Load image 0. U-Boot console Press UP/DOWN to move, ENTER to select, ESC/CTRL+C to quit ``` 4. Choose Option 3: Upgrade Firmware Enter Upgrade Mode Select Option 3 by typing 3 and pressing Enter. Upgrade Methods You will be prompted to choose between: ```plaintext *** Upgrading Firmware *** Run image after upgrading? (Y/n): y Available load methods: 0 - TFTP client (Default) 1 - Xmodem 2 - Ymodem 3 - Kermit 4 - S-Record 5 - RAM Select (enter for default): 0 Input U-Boot's IP address: 192.168.1.1 Input TFTP server's IP address: 192.168.1.10 Input IP netmask: 255.255.255.0 Input file name: wr3000k-<build_time>-mediatek-filogic-tenbay_wr3000k-squashfs-sysupgrade.bin ``` Type Enter to proceed. The router will erase the old firmware and write the new one. Signed-off-by: Jianyu Zhuang <xzjianyu@gmail.com> |

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 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.
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.
