From 6525bffc0a7ee6fabfe331a4d9e3eeabdd3516ae Mon Sep 17 00:00:00 2001 From: Giuseppe Lippolis Date: Sat, 10 Mar 2018 10:34:38 +0100 Subject: [PATCH] ramips: add support for DLINK DWR-921-C1 The DWR-921-C1 Wireless Routers with LTE embedded modem is based on the MT7620N SoC. Specification: * MediaTek MT7620N (580 Mhz) * 64 MB of RAM * 16 MB of FLASH * 802.11bgn radio * 5x 10/100 Mbps Ethernet (1 WAN and 4 LAN) * 2x external, detachable (LTE) antennas * UART header on PCB (57600 8n1) * 6x LED (GPIO-controlled) * 1x bi-color Signal Strength LED (GPIO-controlled) * 2x button * JBOOT bootloader The status led has been assigned to the dwr-921-c1:green:sigstrength (lte signal strength) led. At the end of the boot it is switched off and is available for lte operation. Work correctly also during sysupgrade operation. Installation: Apply factory image via d-link http web-gui. How to revert to OEM firmware: 1.) Push the reset button and turn on the power. Wait until LED start blinking (~10sec.) 2.) Upload original factory image via JBOOT http (IP: 192.168.123.254) 3.) If http doesn't work, it can be done with curl command: curl -F FN=@XXXXX.bin http://192.168.123.254/upg where XXXXX.bin is name of firmware file.
