From 39e9bfb18199b046bd3b613002112e4e6dd53658 Mon Sep 17 00:00:00 2001 From: Henryk Heisig Date: Fri, 15 Dec 2017 15:57:49 +0100 Subject: ramips: add support for TP-Link TL-MR3420 v5 TP-Link TL-MR3420 v5 are simple N300 router with 5-port FE switch and non-detachable antennas. Its very similar to TP-Link TL-WR841N V13. Specification: - MT7628N/N (580 MHz) - 64 MB of RAM (DDR2) - 8 MB of FLASH - 2T2R 2.4 GHz - 5x 10/100 Mbps Ethernet - 2x external, non-detachable antennas - USB 2.0 Port - UART (J1) header on PCB (115200 8n1) - 8x LED, 2x button, power input switch Flash instruction: The only way to flash LEDE image in mr3420v5 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 "lede-ramips-mt7628-tplink_tl-mr3420-v5-squashfs-tftp-recovery.bin" to "tp_recovery.bin" and place it in tftp server directory. 3. Connect PC with one of LAN ports, 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.
