39e9bfb181 ramips: add support for TP-Link TL-MR3420 v5
TP-Link TL-MR3420 v5 are simple N300 router with
5-port FE switch and non-detachable antennas.
Its very similar to TP-Link TL-WR841N V13.

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)
- 8x LED, 2x button, power input switch

Flash instruction:

The only way to flash LEDE image in mr3420v5 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-mr3420-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.

"PandoraBox" is not the name of the manufacturer, it's a firmware made by
the manufacturer actually. Their official English name is "D-Team".

PBR-M1 is the only one they use "PandoraBox" as a brand name. Their other
products are using "Newifi" as their trademark (including Y1 and Y1S which
used to be OEM products for Lenovo).

c0e131b436 ramips: add support for newifi d2
Previously Newifi D2 could only use PandoraBox M1's firmware.
It works fine, but LED GPIO is different.
As a result, a separated DTS file for this device should be implemented.

Hardware spec:

* CPU: MTK MT7621A
* RAM: 512MB
* ROM: 32MB SPI Flash
* 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 firmware flashed. After the device is unlocked, press and hold reset
button before power cable plugs in. Then go to http://192.168.1.1 to
upload and flash the firmware package.

fe6f298b07 ramips: add support for Vonets VAR11N-300
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.

fa36bea470 ramips: add support for UniElec U7628-01
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.

have only added support for the 256/16 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.

2. The manufacturer offers five different wireless cards with MediaTek
chipsets, based on MT76x2, MT7603 and MT7615. Images of the board all
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.

d0ef27594a ramips: add support for TP-Link TL-WR840N v5
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.

f2107fc328 ramips: improve Xiaomi Mi Router 3G support
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.

The factory partition of the Phicomm K2P contains two MAC addresses.
The lower MAC address is at offset 0xe006 and the higher one is at

Use the lower MAC address as base mac-address which the switch driver
increments by one for the second (wan) vlan.

The MAC addresses are still inverted in contrast to the stock firmware
where the lower MAC address is used for wan. But at least the use of a

133815ad8f ramips: fix D240 mini-PCIe power control GPIOs
In commit b11c51916c ("ramips: Improve Sanlinking D240 config") I made
a mistake with regards GPIO numbering. And in addition to specifying the
wrong GPIO for controling the power of one of the mini-PCIe, I recently
discovered that the power of both slots can be controlled.

This patch specifies the correct GPIO for the left-most mini-PCIe slot
of the D240 (labeled power_mpcie2 since the slot is attached to SIM2),
and adds a GPIO that can be used to control the power of the other
mini-PCIe slot (labeled power_mpcie1).

161a3be5ad ramips: add support for TP-Link Archer C20 v1
TP-Link Archer C20 v1 is a router with 5-port FE switch and
non-detachable antennas. It's very similiar to TP-Link Archer C50.
Also it's based on MediaTek MT7620A+MT7610EN.

Specification:
- MediaTek MT7620A (580 Mhz)
- 64 MB of RAM
- 8 MB of FLASH
- 2T2R 2.4 GHz and 1T1R 5 GHz
- 5x 10/100 Mbps Ethernet
- 2x external, non-detachable antennas
- UART (J1) header on PCB (115200 8n1)
- 8x LED (GPIO-controlled*), 2x button, power input switch
- 1 x USB 2.0 port

* WAN LED in this devices 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 blue part of the LED.
* MT7610EN ac chip isn't not supported by LEDE. Therefore 5Ghz won't
  work.

Factory image notes:

These devices use version 3 of TP-Link header, fortunately without RSA
signature (at least in case of devices sold in Europe). The difference
lays in the requirement for a non-zero value in "Additional Hardware
Version" field. Ideally, it should match the value stored in vendor
firmware header on device.

We are able to prepare factory firwmare file which is accepted and
(almost) correctly flashed from the vendor GUI. As it turned out, it
accepts files without U-Boot image with second header at the beginning
but due to some kind of bug in upgrade routine, flashed image gets
corrupted before it's written to flash. So, to flash this device we must
to prepare image using original firmware from tp-link site with uboot.

Flash instruction:

Until (if at all) TP-Link fixes described problem, the only way to flash
LEDE image in these devices is to use tftp recovery mode in U-Boot.
There are two ways to flash the device to LEDE:

1) Using tftp mode with UART connection and original LEDE image

 - Place lede-ramips-mt7620-ArcherC20-squashfs-factory.bin in tftp
   server directory
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - Connect PC with one of LAN ports, power up the router and press
   key "4" to access U-Boot CLI.
 - Use the following commands to update the device to LEDE:

    setenv serverip 192.168.0.66
    tftp 0x80060000 lede-ramips-mt7620-ArcherC20-squashfs-factory.bin
    erase tplink 0x20000 0x7a0000
    cp.b 0x80060000 0x20000 0x7a0000
    reset

 - After that the device will reboot and boot to LEDE

2) Using tftp mode without UART connection but require some
   manipulations with target image

 - Download and unpack TP-Link Archer C20 v1 firmware from original web
   site
 - Split uboot.bin from original firmware by this command (example):

    dd if=Archer_C20v1_0.9.1_4.0_up_boot(160427)_2016-04-27_13.53.59.bin of=uboot.bin bs=512 count=256 skip=1

 - Create ArcherC20V1_tp_recovery.bin using this command:

    cat uboot.bin lede-ramips-mt7620-ArcherC20-squashfs-factory.bin > ArcherC20V1_tp_recovery.bin

 - Place ArcherC20V1_tp_recovery.bin in tftp server directory.
 - Configure PC with static IP 192.168.0.66/24 and tftp server.
 - 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.
 - Router will download file from server, write it to flash and reboot.

79440ea756 ramips: Add support for ZBT WE1026-5G
The ZBT WE1026-5G
(http://www.zbtlink.com/products/router/WE1026-5G.html) is the follow-up
to the ZBT WE1026 and is based on MT7620. For the previous WE1026, the
ZBT WE826 image could be used. However, as the name implies, the -5G
comes equipped with a 5GHz wifi radio. As the WE826 only has a 2.4GHz
radio, the addition of 5GHz means that a separate image is needed for
the WE1026-5G. I suspect that this image will also work on the previous
WE1026, but I don't have a device to test with.

The WE1026-5G has following specifications:
* CPU: MT7620A
* 1x 10/100Mbps Ethernet.
* 16 MB Flash.
* 64 MB RAM.
* 1x USB 2.0 port.
* 1x mini-PCIe slots.
* 1x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x 5GHz wifi (MT7612)
* 1x button.
* 3x controllable LEDs.

Works:
* Wifi.
* Switch.
* mini-PCIe slot. Only tested with a USB device (a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).

Not working:
* The 5GHz WIFI LED is completely dead. I suspect the issue is the same
as on other devices with Mediatek 5Ghz wifi-cards/chips. The LED is
controlled by the driver, and mt76 (currently) does not support this.

Not tested:
* SD card reader.

Notes:
* The modem (labeled 3G/4G) and power LEDs are controlled by the
hardware.
* There is a 32MB version of this device available, but I do not have
access to it. I have therefor only added support for the 16MB version,
but added all the required infrastructure to make adding support for the
32MB version easy.

Installation:
The router comes pre-installed with OpenWRT, including a variant of
Luci. The initial firmware install can be done through this UI,
following normal procedure. I.e., access the UI and update the firmware
using the sysupgrade-image. Remember to select that you do not want to
keep existing settings.

Recovery:
If you brick the device, the WE1026-5G supports recovery using HTTP. Keep the
reset button pressed for ~5sec when booting to start the web server. Set the
address of the network interface on your machine to 192.168.1.2/24, and
point your browser to 192.168.1.1 to access the recovery UI. From the
recovery UI you can upload a firmware image.

* 1x 10/100Mbps Ethernet.
* 16 MB Flash.
* 64 MB RAM.
* 1x USB 2.0 port. Only power is connected, this port is meant for
charging other devices.
* 1x mini-PCIe slots.
* 1x SIM slots.
* 1x 2.4Ghz WIFI.
* 1x button.
* 6000 mAh battery.
* 5x controllable LEDs.

Works:
* Wifi.
* Switch.
* mini-PCIe slot. Only tested with a USB device (a modem).
* SIM slot.
* Sysupgrade.
* Button (reset).

Not working (also applies to the factory firmware):
* Wifi LED. It is always switched on, there is no relation to the
up/down state or activity of the wireless interface.

Not tested:
* SD card reader.

Notes:
* The C108 has no dedicated status LED. I therefore set the LAN LED as
status LED.

Installation:
The router comes pre-installed with OpenWRT, including a variant of
Luci. The initial firmware install can be done through this UI,
following normal procedure. I.e., access the UI and update the firmware

reset button pressed for ~5sec when booting to trigger TFTP. Set the
address of the network interface on your machine to 10.10.10.3/24, and

6e283cdc0d ramips: add Xiaomi Mi Router 3G support
This commit adds support for Xiaomi Mi WiFi Router 3G.

Short specification:
 - MT7621AT + MT7603EN + 7612EN
 - 256MB DDR3 RAM
 - 128MB NAND flash
 - 1+2 x 1000M Ethernet
 - 1x USB 3.0 port
 - reset button
 - yellow, blue, red leds

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: mtd erase kernel0
- run: reboot

Originally stock firmware has following partitions:
 - ...
 - kernel0 (primary kernel image)
 - kernel1 (secondary kernel image, used by u-boot in failsafe routine)
 - rootfs0 (primary rootfs)
 - rootfs1 (secondary rootfs in case primary fails)
 - overlay (used as ubi overlay)

This commit squashes rootfs0, rootfs1 and overlay partitions into 1, so
it can be used by LEDE fully for package installation, resulting in 117,5MiB.

This device lacks hw watchdog, so adding softdog instead (stock does the same).

a92c64e8ae ramips: add support for Loewe WMDR-143N
The WMDR-143N is a small module originally used as a Wifi client
in some Loewe smart TV sets. It is sold cheaply at german surplus
shops. The module contains a RT3662 SOC.

Specifications:

- 500 MHz CPU Clock
- 1x 10/100Mbps Ethernet (pin header)
- 32 MB of RAM
- 8 MB of FLASH
- 2T3R 2.4/5 GHz (SOC internal)
- 3 Antennas on PCB
- UART pads on PCB (J3: 1 = +3.3V, 2 = RX, 3 = TX, 4 = GND), TX
  and RX are 3,3V only! The square hole is pin 1
- Power supply pads on PCB (J6: 1 and 2 = +5V, 3 and 4 = GND)
  The square hole is pin 1

The original firmware has two identical kernel/rootfs images and
two "Factory" calibration data blocks in flash. The LEDE image
leaves only the first "Factory" block in place and uses both
"Kernel" blocks and the redundant "Factory" block together to gain
enough space for the jffs2 partition.

Flash instructions:

You need UART and Ethernet connections to flash the board. Use
the LEDE "sysupgrade.bin" image with tftp.

Apply power to the board and in the first 5 seconds, hit 2 to
select TFTP upload. The bootloader asks for board- and server IP
addresses and filename.

Alternate method: With the vendor firmware running, assign an IP
address to the ethernet port, tftp the firmware image to
/tmp and write to mtd4 ("KernelA").
