From 47de2c686291e69afc9f443e27e1dfd11ed5fbe7 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Thu, 23 Mar 2023 23:53:47 +0100 Subject: [PATCH] ramips: add support for Mercusys MR70X Hardware ======== - SoC: MediaTek MT7621AT (880MHz, Duel-Core) - RAM: DDR3 128MB - Flash: Winbond W25Q128JV (SPI-NOR 16MB) - WiFi: MediaTek MT7915D (2.4GHz, 5GHz, DBDC) - Ethernet: MediaTek MT7530 (WAN x1, LAN x3, SoC) - UART: >TX RX GND 3v3 (115200 8N1, J1) Do not connect 3v3. TX is marked with an arrow. Installation ============ Flash factory image. This can be done using stock web ui. Revert to stock firmware ======================== Flash stock firmware via OEM Web UI Recovery mode. Web UI Recovery method ====================== 1. Unplug the router 2. Plug in and hold reset button 5~10 secs 3. Set your computer IP address manually to 192.168.1.x / 255.255.255.0 4.
