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.
