This is an industrial 4G router equipped with OpenWrt 14.07 OEM customized version WARNING: The original firmware device tree is common to multiple boards, and the device tree name is H9350. This submitted device tree is a modified version, which deletes the non-this-device parts and adds GPIO watchdog. Specification: - SoC: MediaTek MT7620A - Flash: 16 MB - RAM: 128 MB - Power: DC 5V-36V 1.5A - Ethernet: 1x WAN, 4x LAN (10/100 Mbps) - Wireless radio: 802.11n 2.4g-only - LED: System/Power (RUN): GPIO/26 active-low Ethernet: 1x WAN, 4x LAN Modem 1: GPIO/66 active-low RF 1 (Modem 1 Signal): GPIO/67 active-low Modem 2: GPIO 71 active-low RF 2 (Modem 2 Signal): GPIO/24 active-low WLAN: GPIO/72 active-low WPS: GPIO/12 active-low - Button: WPS / RESET: GPIO/34 active-low - UART: 1x UART on PCB - 115200 8N1 - GPIO Watchdog: GPIO/62 mode=toggle timeout=1s - PCIe: 2x miniPCIe for modem - SIM Slots: 2x SIM Slots Issue: - No factory partition, eeprom is located at /lib/firmware/mt7620a.eeprom Flash instruction: Using UART: 1. Configure PC with a static IP address and setup an TFTP server. 2. Put rootfs into the tftp directory. 3. Connect the UART line as described on the PCB. 4. Power up the device and press Ctrl+C to break auto boot. 5. Use `system 6` command and follow the instruction to set device and tftp server IP address and input the rootfs file name. U-boot will then load the rootfs and write it into the flash. 6. Use `system 1` command and follow the instruction to set device and tftp server IP address and input the firmware file name. U-boot will then load the firmware once. 7. Login to LuCI and use LuCI upgrade firmware.

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 -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
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.
