The Unielec U7621-6
(http://www.unielecinc.com/q/news/cn/p/product/detail.html?qd_guid=pyrEjfTmYf)
is an MT7621-based router with the following specifications:
* CPU: MT7621 (880Mhz)
* 5x 10/100/1000Mbps ports.
* 8/16/32/64 MB Flash.
* 256/512 MB RAM.
* 1x USB 3.0 port.
* 1x mini-PCIe slot intended for either a modem or an mSata disk.
* 2x normal mini-PCIe slots.
* 1x SIM slots.
* 1x button.
* 1x mico SD-card reader.
Works:
* Wifi.
* Switch.
* The normal mini-PCIe slots.
* The modem/mSata mini-PCIe slot (only tested with a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).
* micro SD-card reader.
Not working:
-
Notes:
* According to the specifications on the Unielec website, two LEDs
should be controllable via GPIO. I was not able to find the pins.
* The device can be delivered with different amounts of RAM and
storage. I have only added support for devices with 256MB RAM and 16MB
storage, as that is the configuration of my device. However, I have
added all the required infrastructure for making adding support for the
other configurations easy.
* I have assumed that the placement of wifi cards will be as on the image on
the Unielec website linked to above.
* The factory firmware reads the MAC address from offset e000 on the
factory partition. On my device, this offset contains 0xffs, but I have
chosen to keep the offset in the dts to ensure we are consistent with
the factory firmware.
Installation:
See Recovery below. The router comes pre-installed with OpenWRT (Pandora
Box), but sysupgrade fails due to board name mismatch.
Recovery:
The U7621-6 supports web recovery. If you keep the reset-button pressed
for ~5 seconds during boot, a webserver is started. Your machine will be
assigned an IP through DHCP, and the router has address 192.168.1.1. The
recovery website is in Chinese, but is easy to use. Click on the second
item in the list to access the recovery page, then the second item on
the next page is where you select the firmware. In order to start the
recovery, you click the button at the bottom.
