From 0ab9f283f75ad8314ad4be7c70d1397e9dbbfe15 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Thu, 16 May 2019 15:09:07 +0800 Subject: [PATCH] ramips: add support for TOTOLINK LR1200 Specifications: - SoC: MT7628DAN (MT7628AN with 64MB built-in RAM) - Flash: 8M SPI NOR - Ethernet: 5x 10/100Mbps - WiFi: 2.4G: MT7628 built-in 5G: MT7612E - 1x miniPCIe slot for LTE modem (only USB pins connected) - 1x SIM slot Flash instruction: U-boot has a builtin web recovery page: 1. Hold the reset button while powering it up 2. Connect to the ethernet and set an IP in 192.168.1.0/24 range 3. Open your browser and upload firmware through http://192.168.1.1 Note about the LTE modem: If your router comes with an EC25 module and it doesn't show up as a QMI device, you should do the following to switch it to QMI mode: 1. Install kmod-usb-serial-option and a terminal software (e.g. minicom or screen). All 4 serial ports of the modem should be available now. 2. Open /dev/ttyUSB3 with the terminal software and type this AT command: AT+QCFG="usbnet",0 3. Power-cycle the router. You should now get a QMI device recognized.
