From 99dd2709b855baa9e68c7c7106743a7c4a91ee0c Mon Sep 17 00:00:00 2001 From: Yong-hyu Ban Date: Mon, 7 Oct 2019 05:06:31 +0900 Subject: ramips: add support for ipTIME A8004T ipTIME A8004T is a 2.4/5GHz band AC2600 router, based on Mediatek MT7621A. Specifications: - SoC: MT7621A - RAM: DDR3 256M - Flash: SPI NOR 16MB - WiFi: - 2.4GHz: MT7615E - 5GHz: MT7615E - Ethernet: 5x 10/100/1000Mbps - Switch: SoC internal - USB: 1 * USB3.0 port - UART: - J4: 3.3V, TX, RX, GND (3.3V is the square pad) / 57600 8N1 - Other info: - J9: Unknown unpopulated header. 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.
