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:
I got the same board last week and had some initial support ready
locally. I pushed it now to my staging tree, please have a look:
https://git.lede-project.org/?p=lede/pepe2k/staging.git;a=shortlog;h=refs/heads/ramips_unielec-u7621-06
Maybe we can combine our patches and work out a common version.
Please, find also my comments below.

Notes:
* According to the specifications on the Unielec website, two LEDs
should be controllable via GPIO. I was not able to find the pins.
GPIOs 10, 11 and 12 control LEDs 3, 4 and 5 in top row. At least on my
board, some of these LEDs were rotated (wrong polarization).
* 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.
AFAIK, board with 256/16 MB is the default one (mass production?). Any
change means MOQ and customized version. The default one can be easily
purchased from Ali..., directly from the vendor.
It is the same as with some of the ZBT boards. They're advertised with
different RAM sizes, but so far all known boards have the same amount of
ram.
Not sure about the flash size. Especially for the ZBT boards it is known
that they are shipped with different sized flash chips.
But since you pepe have a way better insight what the OEMs/ODMs tend to
do, it would be the best to follow your advice.
* I have assumed that the placement of wifi cards will be as on the
image on
the Unielec website linked to above.
I have problem with this and I don't know how we should proceed here
(Mathias, what do you think?).
Actually, the board by default comes without any Wi-Fi card installed
and they need to be ordered separately (if someone needs them at all).
Oh, I missed that detail.
Personally, I don't think we should force any type of card and/or order
in slots. The board comes with two miniPCIe slots which can be used for
almost anything. I've been testing it with ath9k and mt7603 based cards,
a different configuration than yours :)
I totally agree. If the board isn't ship with a particular set of
wireless cards, we shouldn't enforce anything.
* 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.
AFAIK, the firmware vendor provides board with doesn't come from them.
They installed some version dedicated for PandoraBox PBR-M1.
There is also some dedicated Padavan version but I have no idea where it
can be downloaded from.
Installation:
See Recovery below. The router comes pre-installed with OpenWRT (Pandora
Box), but sysupgrade fails due to board name mismatch.
sysupgrade -F ...
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.
At least on my board, button just stops autobooting process. Web server
seems to be enabled in the bootloader all the time - with a static IP on
my PC I can access it even during autobooting countdown.
Pepe, are you fine if I handle this patch over to you? Doesn't make much
sense to me if I do the review, while you are having the hardware.
Mathias
