From 73e8f23579bcb87764dae9ed0aefe28be3183d3e Mon Sep 17 00:00:00 2001 From: "Mateus B. Cassiano" Date: Wed, 15 Jul 2020 17:45:39 -0400 Subject: ramips: add support for D-Link DIR-867/DIR-882 A1 This patch adds support for D-Link DIR-867 A1 and D-Link DIR-882 A1. Given the similarity of these devices, this patch also introduces a common DTS shared between DIR-867 A1, DIR-878 A1 and DIR-882 A1. Specifications: * Board: AP-MTKH7-0002 * SoC: MediaTek MT7621AT * RAM: 128 MB (DDR3) * Flash: 16 MB (SPI NOR) * WiFi: MediaTek MT7615N (x2) * Switch: 1 WAN, 4 LAN (Gigabit) * Ports: 1 USB 2.0, 1 USB 3.0 * Buttons: Reset, WiFi Toggle, WPS * LEDs: Power (green/orange), Internet (green/orange), WiFi 2.4G (green), WiFi 5G (green), USB 2.0 (green), USB 3.0 (green) Notes: * WiFi 2.4G and WiFi 5G LEDs are wired directly to the wireless chips * DIR-867 wireless chips are limited to 3x3 streams at hardware level * USB ports and related LEDs available only on DIR-882 Serial port: * Parameters: 57600, 8N1 * Location: J1 header (close to the Reset, WiFi and WPS buttons) * Pinout: 1 - VCC 2 - RXD 3 - TXD 4 - GND Installation: * D-Link Recovery GUI: power down the router, press and hold the reset button, then re-plug it. Keep the reset button pressed until the power LED starts flashing orange, manually assign a static IP address under the 192.168.0.xxx subnet (e.g. 192.168.0.2) and go to http://192.168.0.1 * Some modern browsers may have problems flashing via the Recovery GUI, if that occurs consider uploading the firmware through cURL: curl -v -i -F "firmware=@file.bin" 192.168.0.1 Signed-off-by: Mateus B.
