From 6bbb2202551be394fead2efd99eb946f846fc63d Mon Sep 17 00:00:00 2001 From: Carlo Nel Date: Sun, 26 Aug 2018 21:11:59 +0200 Subject: [PATCH] ramips: add support for TP-Link TL-MR3020 v3 TP-Link TL-MR3020 v3 is a pocket-size router based on MediaTek MT7628N. This PR is based on the work of @meyergru[1], with his permission. Specification: - MediaTek MT7628N/N (575 Mhz) - 64 MB of RAM - 8 MB of FLASH - 2T2R 2.4 GHz - 1x 10/100 Mbps Ethernet Flash instruction: The only way to flash the image in TL-MR3020 v3 is to use tftp recovery mode in U-Boot: 1. Configure PC with static IP 192.168.0.225/24 and tftp server. 2. Rename "openwrt-ramips-mt76x8-tplink_tl-mr3020-v3-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with the LAN port, press the reset button, power up the router and keep button pressed for around 6-7 seconds, until device starts downloading the file. 4. Router will download file from server, write it to flash and reboot.
