From 2dde2416e1a2f7a3208095e29c20132ed9910889 Mon Sep 17 00:00:00 2001 From: WonJung Kim Date: Wed, 22 Dec 2021 15:59:00 +0900 Subject: ramips: add support for ipTIME A3004T ipTIME A3004T is a 2.4/5GHz band router, based on Mediatek MT7621. Specifications: - SoC: MT7621 (880MHz) - RAM: DDR3 256M - Flash: NAND 128MB (Macronix NAND 128MiB 3,3V 8-bit) - WiFi: - 2.4GHz: MT7615E - 5GHz : MT7615E - Ethernet: - 4x LAN - 1x WAN - USB: 1 * USB3.0 port - UART: - 3.3V, TX, RX, GND / 57600 8N1 Installation via web interface: 1. Flash initramfs image using OEM's Recovery mode 2. Boot into OpenWrt and perform sysupgrade with sysupgrade image. Revert to stock firmware: - Flash stock firmware via OEM's Recovery mode How to use OEM's Recovery mode: 1. Power up with holding down the reset key until CPU LED stop blinking. 2. Set fixed ip with `192.168.0.2` with subnet mask `255.255.255.0` 3. Flash image via tftp to `192.168.0.1` Additional Notes: This router shares one MT7915E chip for both 2.4Ghz/5Ghz. radio0 will not working on 5Ghz as it's not connected to the antenna.
