From 58e0673900ea585b03d3cc2f8917667faa3f977f Mon Sep 17 00:00:00 2001 From: Zoltan HERPAI Date: Wed, 6 Dec 2017 15:43:55 +0100 Subject: ramips: add support for Asus RT-N11P / RT-N12+ / RT-N12E b1 This is a variant of the MT7620N-based Asus routers. Specifications: - MT7620N (580 MHz) - 32 MB RAM - 8 MB Flash - 5x 10/100Mbps Ethernet (built-in switch) - 2.4 GHz WLAN - 2x external, non-detachable antennas - UART (J2) header on PCB (115200 8n1) Flash instructions: 1. Configure PC with static IP 192.168.1.75/24 2. Connect PC with one of LAN ports, press the reset button, power up the router and keep button pressed for around 6-7 seconds. All 4 LEDs will start to blink, which is when the router will accept firmware files via TFTP. No known limitations on firmware filenames, just send it with a TFTP client to 192.168.1.1. 3. Router will download file from server, write it to flash and reboot.
