UniElec U7628-01 is a router platform board based on MediaTek MT7628AN.
The device has the following specifications:
- MT7628AN (580MHz)
- 64/128/256 MB of RAM (DDR2)
- 8/16 MB of flash (SPI NOR)
- 5x 10/100 Mbps Ethernet (MT7628 built-in switch)
- 1x 2T2R 2.4 GHz Wi-Fi (MT7628)
- 1x miniPCIe slot (with PCIe and USB 2.0 buses)
- 1x miniSIM slot
- 1x microSD slot
- 1x USB 2.0 port
- 7x single-color LEDs (GPIO-controlled)
- 1x bi-color LED (green GPIO-controlled, red -> LED_WLAN# in miniPCIe)
- 1x reset button
- 1x UART header (4-pins)
- 1x SDXC/GPIO header (10-pins, connected with microSD slot)
- 1x DC jack for main power (12 V)
The following has been tested and is working:
- Ethernet switch
- miniPCIe slot (tested with modem and Wi-Fi card)
- miniSIM slot
- sysupgrade
- reset button
- USB 2.0 port*
Due to a missing driver (MMC over GPIO) this is not supported:
- microSD card reader
* Warning:
USB buses in miniPCIe and regular A-type socket are connected together,
without any proper analog switch or USB HUB.
Installation:
This board might come with a different firmware versions (MediaTek SDK,
PandoraBox, Padavan, etc.). If your board comes with PandoraBox, you can
install LEDE using sysupgrade. Just SSH to the router and perform forced
sysupgrade (due to a board name mismatch). The default IP of this board
should be: 192.168.1.1 and username/password: root/admin. In case of a
different firmware, you can use web based recovery described below.
Use the following command to perform the sysupgrade (for the 128MB
RAM/16MB flash version):
sysupgrade -n -F lede-ramips-mt76x8-u7628-01-128M-16M-squashfs-sysupgrade.bin
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.
SDXC/GPIO header (J3):
1. SDXC_D3 / I2C_SCLK
2. SDXC_D2 / I2C_SD
3. SDXC_D1 / I2S_DI
4. SDXC_D0 / I2S_WS
5. SDXC_CMD / I2S_CLK
6. SDXC_CLK / GPIO0
7. SDXC_CD / UART_RXD1
8. UART_TXD1
9. 3V3
10. GND
Other notes:
1. The board is available with different amounts of RAM and flash. We
have only added support for the 128/16 MB configuration, as that seems
to be the default. However, all the required infrastructure is in place
for making support for the other configurations easy.

TP-Link TL-WR840N v5 is simple N300 router with 5-port FE switch and
non-detachable antennas, based on MediaTek MT7628NN (aka MT7628N) WiSoC.
Specification:
- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 4 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 1x LED (GPIO-controlled), 1x button
* LED in TL-WR840N v5 is a dual-color, dual-leads type which isn't
(fully) supported by gpio-leds driver. This type of LED requires both
GPIOs state change at the same time to select color or turn it off.
For now, we support/use only the green part of the LED.
Orange LED is registered so you can later use it for your own purposes.
Flash instruction:
Unlike TL-WR840N v4 flashing through WEB UI works in v5.
1. Download lede-ramips-mt76x8-tl-wr840n-v5-squashfs-sysupgrade.bin image.
2. Go to 192.168.0.1
3. Flash the sysupgrade image through Firmware upgrade section of WEB UI.
4. Wait until green LED stops flashing and use the router.
Notes:
TFTP recovery is broken since TP-Link reused bootloader code for v4 and
that does not take into account only 4 MB of flash and bricks the device.
So do not use TFTP Recovery or you will have to rewrite SPI flash.
They fixed it in later GPL code,but it is unknown which version of
bootloader you have.
After manually compiling and flashing bootloader from GPL sources TFTP
recovery works properly.

The tplink 841n v13 requires an tplink v2 image header in
front of an initramfs image.
To boot an initramfs image:
- break the uboot by holding the '4' key
- setup your tftp server 192.168.0.255
- tftp 81000000 lede-ramips-mt76x8-tl-wr841n-v13-initramfs-kernel.bin
- bootm

This patch adds all the board-specific values currently hardcoded
in mktplinkfw2.c back to the respective device declarations in the
makefiles.
The rationale is to avoid modifying the source code every time a
new board or board variant is added.

The ramips subtargets of mt7628 and mt7688 dts files all #include "mt7628an.dtsi"
They are essentially a single subtarget.
This patch merges the ramips subtargets mt7628 and mt7688 into a single subtarget mt76x8.
