TP-Link TL-WR842N v5 are simple N300 router with 5-port FE switch and
non-detachable antennas. Its very similar to TP-Link TL-MR3420 V5.
Specification:
- MT7628N/N (580 MHz)
- 64 MB of RAM (DDR2)
- 8 MB of FLASH
- 2T2R 2.4 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- USB 2.0 Port
- UART (J1) header on PCB (115200 8n1)
- 7x LED, 2x button, power input switch
Flash instruction:
The only way to flash OpenWrt image in wr842nv5 is to use
tftp recovery mode in U-Boot:
1. Configure PC with static IP 192.168.0.225/24 and tftp server.
2. Rename "lede-ramips-mt7628-tplink_tl-wr842n-v5-squashfs-tftp-recovery.bin"
to "tp_recovery.bin" and place it in tftp server directory.
3. Connect PC with one of LAN ports, press the reset button, power up
the router and keep button pressed for around 6-7 seconds, until
device starts downloading the file.
4. Router will download file from server, write it to flash and reboot.

With this change, the LED trigger is independent from the (wireless)
netdev name. The (wireless) netdev name can be easiliy changed in
OpenWrt and would require an update of the netdev trigger settings each
time it is done.
This change is (for now) applied only to MT7628 devices from TP-Link, as
we only had the possibility to test this change against two of those
devices, namely a TL-WR841 v13 and a Archer C50 v3.

Define USB port power on/off GPO as voltage regulator type instead of
exposing as a normal GPIO.
The GPO is now controlled by the USB driver via the voltage regulator
definition. The regulator is of fixed output type (5V for USB) hence the
GPO switches power on/off to USB pin 1 (Vcc)
USB port power is enabled on driver load and disabled on driver unload.

Some board vendors actually changed the loader to expect the chip
to come up in 4-address-mode and flipped the ADP bit in the flash
chip's configuration register which makes it come up in 4-address-mode.
Hence it doesn't make sense to avoid switching to 4-address-mode on
those boards but the opposite as otherwise reboot hangs eg. on the
WrtNode2 boards. Fix this by checking the ADP register and only using
SPI_NOR_4B_READ_OP on chips which have ADP==0 (come up in 3-byte mode).

Specifications:
SOC: MediaTek MT7620N
BATTERY: 6000mah
WLAN: 802.11bgn
LAN: 1x 10/100 Mbps Ethernet
USB: 1x USB 2.0 (Type-A)
RAM: PM Tech PMD708416CTR-5CN 32 MB
FLASH: Holtek HT66F40 - 8 MB Flash
LED: Power button and 4 leds to indicate power level of the
battery (could not get control of that)
INPUT: Power, reset button
OTHER: USB SD-Card reader with card detect on GPIO#42
Tested and working:
- Ethernet
- 2.4 GHz WiFi (Correct MAC-address)
- installation from tftp
- OpenWRT sysupgrade (Preserving and non-preserving)
- LEDs
- Buttons
Installation:
- Download the sysupgrade image
- Place it in the root of a clean TFTP server running on your computer.
- Rename the image to "kernel" — be sure there is no file extension.
- Plug the WD03 into your computer via ethernet.
- Set your computer to use 10.10.10.254 as its IP address.
- With your WD03 shut down, hold down the power button until the first
white LED lights up.
- Push and hold the reset button and release the power button. Continue
holding the reset button for 30 seconds or until it begins searching
for files on your TFTP server, whichever comes first.
- The WD03 (10.10.10.128) will look for your computer at 10.10.10.254
and install the kernel file. Once it has finished installation of the
kernel file, it will search for a (nonexistent) rootfs file — when it
begins searching for this file, shut down the WD03 by holding the
power button normally.
- Start up your WD03 normally.

pdev->id is -1 when only one device exists, and is used:
* as an index into drv_mode[] to determine whether to use
PIO or DMA mode (via host->id)
* as an index into msdc_6575_host[], to store the
mmc_priv() data.
Obviously, -1 is not a valid index in either case, causing
us to read invalid memory, and memory corruption,
respectively.
The invalid memory read is causing non-deterministic
behaviour, in particular in the v4.4 kernel it still
picked DMA mode, but in the v4.9 it now always picks
PIO mode.
Also, PIO mode doesn't work, causing the following:

(i.e. initial page-in of any binary causes a segfault,
subsequent access works.)
While this change doesn't fix PIO mode, it at least makes
us deterministically use DMA (which works), and it also

- Six SATA ports for 3.5" Drives
- One SDcard
- One USB 3.0

Flash instructions:
The GnuBee Personal Cloud Two ships with libreCMC installed.
libreCMC is a Free Software Foundation approved fork of LEDE/OpenWrt.
As such one can upgrade using the webinterface or sysupgrade.
Das U-Boot has multiple options for recovery or updates including :
- USB
- http
- tftp
Errata:
- While there are three ethernet ports, the third requires support for
the second GMAC. This will come in kernel 4.14.
- The first hard drive slot has a clearance issue with the two fan
headers. Workaround is to pull the headers out and connect the pins to
jumper wires.
- Using this device as a NAS is problematic with the 4.9 kernel as many
/dev/sdX reads throw silent errors. The current theory behind this is
some kind of unhandled DMA mapping error in the kernel. This is not an
issue with kernel 4.4.

As a result, a separated DTS file for this device should be implemented.
Hardware spec:

* WiFi: MTK MT7603+MT7612
* Button: 2 buttons (reset, wps)
* LED: 3 single-color LEDs (USB, WiFi 2.4GHz, WiFi 5GHz) &
2 dual-color LEDs (Power, Internet)
* Ethernet: 5 ports, 4 LAN + 1 WAN
Installation method:
Same as Newifi D1, users may need to request unlock code from the device
manufacturer. Otherwise, a SPI flash programmer may be necessary to get

The VAR11N-300 is a tiny wireless-N device with a hardwired Ethernet
cable, one extra Ethernet port, and an internal antenna, based on the
MediaTek MT7620n chipset.
Specs:
- MT7620n WiSoC @ 600MHz
- 32 MB SDRAM
- 4 MB SPI flash
- 2T2R 2.4GHz WiFi-N
- 1 attached 10/100 Ethernet cable (LAN)
- 1 10/100 Ethernet port (WAN)
- 1 attached USB / barrel 5vdc power cable
- 5 LEDs (see notes below)
- 1 reset button
- 1 UART (3 pads on board)
Installation:
The stock firmware does not support uploading new firmware directly,
only checking the manufacturer's site for updates. This process may be
possible to spoof, but the update check uses some kind of homebrew
encryption that I didn't investigate. Instead, you can install via a
backdoor:
1. Set up a TFTP server to serve the firmware binary
(lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin)
2. Factory reset the device by holding the reset button for a few
seconds.
3. Open the web interface (default IP: 192.168.253.254)
4. Log in with the "super admin" credentials: username `vonets`,
password `vonets26642519`.
5. On the "Operative Status" page, click the text "System Uptime", then
quickly click the uptime value.
6. If successful, an alert dialog will appear reading "Ated start", and
the device will now accept telnet connections. If the alert does not
appear, repeat step 5 until it works (the timing is a bit tricky).
7. Telnet to the device using credentials "admin / admin"
8. Retrieve the firmware binary from the tftp server: `tftp -l lede.bin
-r lede-ramips-mt7620-var11n-300-squashfs-sysupgrade.bin -g
<tftp-server-ip>`
9. Write the firmware to flash: `mtd_write write lede.bin /dev/mtd4`
10. Reboot
Tested:
- LAN / WAN ethernet
- WiFi
- LAN / WAN / status LED GPIOs (see notes below)
- Reset button
- Sysupgrade
Notes:
LEDs:
The board has 5 LEDs - two green LEDs for LAN / WAN activity, one blue
LED for WiFi, and a pair of "status" LEDs connected to the same GPIO
(the blue LED lights when the GPIO is low, and the green when it's
high). I was unable to determine how to operate the WiFi LED, as it
does not appear to be controlled by a GPIO directly.
Recovery:
The default U-boot installation will only boot from flash due to a
missing environment block. I generated a valid 4KB env block using
U-boot's `fw_setenv` tool and wrote it to flash at 0x30000 using an
external programmer. After this, it was possible to enter the U-boot
commandline interface and download a new image via TFTP (`tftpboot
81b00000 <image-filename>`), but while I could boot this image
sucessfully (`bootm`), writing it to flash (`cp.linux`) just corrupted
the flash chip. The sysupgrade file can be written to flash at 0x50000
using an external programmer.

Add a helper variable which contains the boardname separated from the
vendor name. It allows to switch to a device tree compatible string
based boardname, by keeping the $board:colour:function syntax in
scripts handling/adding config for LEDs.
Boards not using the device tree compatible string as based boardname
are unaffected by the change, since none of them uses a comma in the
boardname.

- 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)

- 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

2. The manufacturer offers five different wireless cards with MediaTek

show that the miniPCIe slots are dedicated to specific Wi-Fi cards.
However, the slots are generic.
3. All boards we got access to had the same EEPROM content. The default
firmware reads the Ethernet MAC from offset 0xe000 in factory partition.
This offset only contains 0xffs, so a random MAC will be generated on
every boot of the router. There is a valid MAC stored at offset 0xe006
and this MAC is shown as the WAN MAC in the bootloader. However, it is
the same on all boards we have checked. Based on information provided
by the vendor, all boards sold in small quantities are considered more
as samples for development purposes.

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.

Some targets need 4K sectors for small flash chips (e.g. some
routerboards, where the entire chip is just one "erase block"), whereas
on other devices 4K sectors lead to horrible flash erase/write
performance.
Set the default limit in the generic kernel configuration to 4 MiB to
ensure that all new platforms don't use 4K sectors for bigger flash
chips. On all existing targets use 16 MiB for now to avoid regressions.

On some devices the flash chip needs to be in 3-byte addressing mode during
reboot, otherwise the boot loader will fail to start.
This mode however does not allow regular reads/writes onto the upper 16M
half. W25Q256 has separate read commands for reading from >16M, however
it does not have any separate write commands.
This patch changes the code to leave the chip in 3-byte mode most of the
time and only switch during erase/write cycles that go to >16M
addresses.

This commit improves support for the Xiaomi Mi Router 3G originally
added in commit 6e283cdc0d
Improvements:
- Remove software watchdog as hardware watchdog now working as per
commit 3fbf3ab44f for all mt7621
devices.
- Reset button polarity corrected - length of press determines reboot
(short press) vs. reset to defaults (long press) behaviour.
- Enable GPIO amber switch port LEDs on board rear - lit indicates 1Gbit
link and blink on activity. Green LEDs driven directly by switch
indicating any link speed and tx activity.
- USB port power on/off GPIO exposed as 'usbpower'
- Add access to uboot environment settings for checking/setting uboot
boot order preference from user space.
Changes:
- Front LED indicator is physically made of independent Yellow/Amber,
Red & Blue LEDs combined via a plastic 'lightpipe' to a front panel
indicator, hence the colour behaviour is similar to an RGB LED. RGB
LEDs are not supported at this time because they produce colour results
that do not then match colour labels, e.g. enabling 'mir3g:red' and
'mir3g:blue' would result in a purple indicator and we have no such
label for purple.
The yellow, red & blue LEDs have been split out as individual yellow,
red & blue status LEDs, with yellow being the default status LED as
before and with red's WAN and blue's USB default associations removed.
- Swapped order of vlan interfaces (eth0.1 & eth0.2) to match stock vlan
layout. eth0.1 is LAN, eth0.2 is WAN
- Add 'lwlll' vlan layout to mt7530 switch driver to prevent packet
leakage between kernel switch init and uci swconfig
uboot behaviour & system 'recovery'
uboot expects to find bootable kernels at nand addresses 0x200000 &
0x600000 known by uboot as "system 1" and "system 2" respectively.
uboot chooses which system to hand control to based on 3 environment
variables: flag_last_success, flag_try_sys1_failed & flag_try_sys2_failed
last_success represents a preference for a particular system and is set
to 0 for system 1, set to 1 for system 2. last_success is considered *if*
and only if both try_sys'n'_failed flags are 0 (ie. unset) If *either*
failed flags are set then uboot will attempt to hand control to the
non failed system. If both failed flags are set then uboot will check
the uImage CRC of system 1 and hand control to it if ok. If the uImage
CRC of system is not ok, uboot will hand control to system 2
irrespective of system 2's uImage CRC.
NOTE: uboot only ever sets failed flags, it *never* clears them. uboot
sets a system's failed flag if that system's was selected for boot but
the uImage CRC is incorrect.
Fortunately with serial console access, uboot provides the ability to
boot an initramfs image transferred via tftp, similarly an image may
be flashed to nand however it will flash to *both* kernels so a backup
of stock kernel image is suggested. Note that the suggested install
procedure below set's system 1's failed flag (stock) thus uboot ignores
the last_success preference and boots LEDE located in system 2.
Considerable thought has gone into whether LEDE should replace both
kernels, only one (and which one) etc. LEDE kernels do not include a
minimal rootfs and thus unlike the stock kernel cannot include a
method of controlling uboot environment variables in the event of
rootfs mount failure. Similarly uboot fails to provide an external
mechanism for indicating boot system failure.
Installation - from stock.
Installation through telnet/ssh:
- copy lede-ramips-mt7621-mir3g-squashfs-kernel1.bin and
lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin to usb disk or wget it
from LEDE download site to /tmp
- switch to /extdisks/sda1/ (if copied to USB drive) or to /tmp if
wgetted from LEDE download site
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-kernel1.bin kernel1
- run: mtd write lede-ramips-mt7621-mir3g-squashfs-rootfs0.bin rootfs0
- run: nvram set flag_try_sys1_failed=1
- run: nvram commit
- run: reboot
Recovery - to stock.
Assuming you used the above installation instructions you will have a
stock kernel image in system 1. If it can be booted then it may be used
to perform a stock firmware recovery, thus erasing LEDE completely. From
a 'working' LEDE state (even failsafe)
Failsafe only:
- run: mount_root
- run: sh /etc/uci-defaults/30_uboot-envtools
Then do the steps for 'All'
All:
- run: fw_setenv flag_try_sys2_failed 1
- run: reboot
The board will reboot into system 1 (stock basic kernel) and wait with
system red light slowly blinking for a FAT formatted usb stick with a
recovery image to be inserted. Press and hold the reset button for
around 1 second. Status LED will turn yellow during recovery and blue
when recovery complete.
