From a972b1fb5f5d5c159b0310b3623cfd5442a5c322 Mon Sep 17 00:00:00 2001 From: Sungbo Eo Date: Tue, 12 Nov 2019 01:25:31 +0900 Subject: [PATCH] ramips: add support for ipTIME A6ns-M ipTIME A6ns-M is a 2.4/5GHz band AC1900 router, based on MediaTek MT7621A. Specifications: - SoC: MT7621AT - RAM: DDR3 128MB - Flash: SPI NOR 16MB - WiFi: - 2.4GHz: MT7615 - 5GHz: MT7615 - Ethernet: 5x 10/100/1000Mbps - Switch: SoC internal - UART: - J4: 3.3V, TX, RX, GND (3.3V is the square pad) / 57600 8N1 Installation via web interface: 1. Flash **initramfs** image through the stock web interface. 2. Boot into OpenWrt and perform sysupgrade with sysupgrade image. Revert to stock firmware: 1. Perform sysupgrade with stock image.
