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.
