While the latest version of 19.07 release is usable,
the current master is unbootable on the device in a normal way.
"Normal way" installations includes:
- sysupgrade (e.g. from 19.07)
- RESET button recovery with Ron Curry's (Wingspinner) UBoot image
(10.10.10.3 + "Kernal.bin")
- RESET button recovery with original U-Boot
(10.10.10.254 + "kernel")
One could flash and boot the latest master sysupgrade image successfully
with serial access to the device. But a sysupgrade from this state still
breaks the U-Boot and soft-bricks the device.

UniElec U7621-01 is a router platform board, the smaller model of
the U7621-06.
The device has the following specifications:
- MT7621AT (880 MHz)
- 256 of RAM (DDR3)
- 16 MB of FLASH (SPI NOR)
- 5x 1 Gbps Ethernet (MT7621 built-in switch)
- 1x 2.4Ghz MT7603E
- 1x 5Ghz MT7612
- 1x miniPCIe slots (PCIe bus only)
- 1x miniSIM slot
- 1x USB 2.0 (uses the usb 3.0 driver)
- 8x LEDs (1x GPIO-controlled)
- 1x reset button
- 1x UART header (4-pins)
- 1x GPIO header (30-pins)
- 1x DC jack for main power (12 V)
The following has been tested and is working:
- Ethernet switch
- 1x 2.4Ghz MT7603E (wifi)
- 1x 5Ghz MT7612 (wifi)
- miniPCIe slots (tested with Wi-Fi cards and LTE modem cards)
- miniSIM slot (works with normal size simcard)
- sysupgrade
- reset button
Installation:
This board has no locked down bootloader. The seller can be asked to
install openwrt v18.06, so upgrades are standard sysupgrade method.
Recovery:
This board contains a Chinese, closed-source bootloader called Breed
(Boot and Recovery Environment for Embedded Devices). Breed supports web
recovery and to enter it, you keep the reset button pressed for around
5 seconds during boot. Your machine will be assigned an IP through DHCP
and the router will use IP 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.
LEDs list (left to right):
- ESW_P0_LED_0
- ESW_P1_LED_0
- ESW_P2_LED_0
- ESW_P3_LED_0
- ESW_P4_LED_0
- CTS2_N (GPIO10, configured as "status" LED)
- LED_WLAN# (connected with pin 44 in wifi1 slot)

[add DEVICE_VARIANT, fix DEVICE_PACKAGES, remove &gpio]
Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))
(Though this is not precisely an achievement of this commit.)

TP-Link RE200 v4 is a wireless range extender with Ethernet and 2.4G and 5G
WiFi with internal antennas.
It's based on MediaTek MT7628AN+MT7610EN like the v2/v3.
Specifications
--------------
- MediaTek MT7628AN (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 1x 10/100 Mbps Ethernet
- 8x LED (GPIO-controlled), 2x button
- UART connection holes on PCB (57600 8n1)
There are 2.4G and 5G LEDs in red and green which are controlled
separately.
MAC addresses
-------------
The MAC address assignment matches stock firmware, i.e.:
LAN : *:8E
2.4G: *:8D
5G : *:8C
MAC address assignment has been done according to the RE200 v2.
The label MAC address matches the OpenWrt ethernet address.
Installation
------------
Web Interface
-------------
It is possible to upgrade to OpenWrt via the web interface. Simply flash
the -factory.bin from OEM. In contrast to a stock firmware, this will not
overwrite U-Boot.
Recovery
--------
Unfortunately, this devices does not offer a recovery mode or a tftp
installation method. If the web interface upgrade fails, you have to open
your device and attach serial console.
Instructions for serial console and recovery may be checked out in
commit 6d6f36ae78 ("ramips: add support for TP-Link RE200 v2") or on
