From: Til Kaiser Date: Mon, 24 Nov 2025 14:50:33 +0000 (+0100) Subject: ramips: mt76x8: add Teltonika RUT976 support X-Git-Url: http://git.openwrt.org/?a=commitdiff_plain;h=5629e06cf211cffb19f370b5b098f3d46e1e80bb;p=openwrt%2Fopenwrt.git ramips: mt76x8: add Teltonika RUT976 support This commit adds support for the Teltonika RUT976, part of the RUTE series, which is very similar to the RUT956. The RUT976 now has a 5G modem and the flash size has doubled. Specification: - MediaTek MT7628AN SoC - 128 MB RAM - 32MB Flash - 4x 10/100 Mbps Ethernet, with passive PoE support on LAN1 - MediaTek MT7628AN 2.4 GHz 802.11n WiFi - Quectel RG255C 5G modem - GNSS - RS232, DB9 connector, Cypress ACM via USB, /dev/ttyACM0 - RS485 /dev/ttyS1 - microSD card slot - 2.0 USB Type-A HOST port - analog 0-24V input (MCP3221) - Relay - 2x Digital input - 2x Digital output - 2x SIM slot (can be swapped via GPIO) - eSIM (depends on hardware configuration, can be swapped via GPIO) GPIO: - 1 button (Reset) - 7 LEDs (power, status green/red, RSSI 1,2,3,4,5) - 5 Modem control (power button, reset, status, SIM select, eSIM select) - 2 Digital input - 2 Digital output - 1 Isolated input - 1 RS485 tx enable - 1 RS485 rx enable - 1 Relay - 1 Data Carrier Detect (DCD) Flashing via OEM WebUI: 1. Download the firmware image *-squashfs-factory.bin 2. Upload firmware image via OEM WebUI firmware update, do not keep settings To revert back to OEM firmware: https://wiki.teltonika-networks.com/view/Bootloader_menu Mobile data connection: Create proto qmi interface.
