Specification: - MT7629 CPU - MT7531 switch - MT7761N and MT7762N wifi - 256 MB RAM - 128 MB NAND flash with dual-boot partitions - 2 buttons: WPS and reset - 1 WAN port (1G) - 4 LAN ports (1G) - 1 USB port Limitations (same as other MT7629/MT7761N/MT7762N devices): - Wifi is not working - Second core is not working (kernel error message "CPU1: failed to come online") Disassembly: - There are two screws under the front rubber feet and two under the label on the bottom (in the corners towards the back, you should be able to feel them). Serial Interface: - UART pin header is already soldered on the board. Pinning from front to back: 1 - VCC 2 - TX 3 - RX 4 - n/a 5 - GND GPIO: - 1 white LED, connected to GPIO 52 - 1 reset button, connected to GPIO 60 - 1 WPS button, connected to GPIO 58 MAC Adresses: - The MAC address printed on the device label is used for LAN and WAN - The MAC address is stored in the devinfo partition in ASCII format (hw_mac_addr=aa:bb:cc:dd:ee) - 2.4 GHz wifi uses MAC of the device label + 1 - 5 GHz wifi uses MAC of the device label + 2 Flashing: - OpenWrt is only runnig in the first partition of dual boot - To ensure to be able to go back to the factory image, flash the last OEM firmware via OEM web interface. This will ensure that the OEM firmware is present on both partitions - Because of dual boot partitions, flashing via OEM interface is not supported - Start a TFTP server and provide the initramfs image. Default settings: - Router IP: 192.168.1.1 - TFTP server IP: 192.168.1.100 - TFTP file name: 7531.bin - Open the device, connect UART and select " 1. System Load Linux to SDRAM via TFTP." during startup - Adapt the settings to your environment, if required - After initramfs is booted, flash the sysupgrade image Return to OEM firmware: - Run the following commands in OpenWrt to switch to the second partition fw_setenv boot_part 2 fw_setenv bootimage 2 - Reboot the device. OEM firmware will start up again Signed-off-by: Roland Reinl <reinlroland+github@gmail.com> Link: https://github.com/openwrt/openwrt/pull/16067 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de>
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.
