     2: System Load Linux Kernel then write to Flash via TFTP.
        Warning!! Erase Linux in Flash then burn new one. Are you sure?
 - Push "y", and enter: device IP, then TFTP server's IP, and then
   image firmware file name.

The firmware will be downloaded within ~30 seconds and flashed to the
device (It will take about 2 minutes).

This device features both a 2.4 and 5Ghz radio, and supports
802.11a/b/g/n/ac modes.
It has 5 Gb-Ethernet ports and a USB 3.0 host port.

It is powered by the Mediatek MT7621 SoC, and the MT7602E and MT7612E wifi
chipsets, together with 128MB of RAM and 16 MB of SPI Flash.

The stock firmware is in fact based on some openwrt barrier breaker, with a
mediatek SDK kernel, and an afoundry custom made web interface (not LuCI
based).
Firmware update page on the stock web interface can not accept sysupgrade
images, it bricks the device.
At this point, the only working solution I found was to connect to the
serial console port (available on J4 header) and to use opkg to install
dropbear.
Then scp the sysupgrade file in the device's /tmp and run sysupgrade from
console without preserving configuration files.

Some boards were apparently forgotten when ralink,portmap was renamed
to mediatek,portmap -- probably because they used the long obsolete
ralink,port-map attribute.
If this commit breaks ethernet wan/lan assignment, this is because
the port-map attribute wasn't actually parsed, you'll have to replace
"wllll" by "llllw" in the dts file belonging to that board (and send

The Sanlinking Technologies D240
(http://www.sanlinking.com/en/29-dual-4g-wifi-router.html

) is basically the same
device as the ZBT WE826, so adding support for it in LEDE is straight forward.
The differences is that the D240 has two mini-PCIe slots (instead of one), blue
LEDs and supports PoE.

Specification:
* CPU: MT7620A
* 1x 10/100Mbps POE (802.3af/802.3at) Ethernet, 4x 10/100Mbps.
* 16 MB Flash.
* 128 MB RAM.
* 1x USB 2.0 port.
* 2x mini-PCIe slots.
* 2x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x button.

Wifi, USB, switch and both mini-PCIe slots are working. I have not been able to
test the SD card reader.

The device comes pre-installed with an older version of OpenWRT, including Luci.
In order to install LEDE, you need to follow the existing procedure for updating
OpenWRT/LEDE using Luci. I.e., you need to access the UI and update the firmware
using the sysupgrade-image. Remember to select that you do not want to keep
existing settings. The default router address is 192.168.10.1 and
username/password admin/root (at least on my devices).

If you brick the device, the procedure for recovery is the same as for the
WE826. Please see the wiki page for that device for instructions.
