Partition layout and boot:
Stock Xiaomi firmware has the MTD split into (among others)
- kernel0 (@0x200000)
- kernel1 (@0x600000)
- rootfs0
- rootfs1
- overlay (ubi)
Xiaomi uboot expects to find kernels at 0x200000 & 0x600000
referred to as system 1 & system 2 respectively.
a kernel is considered suitable for handing control over
if its linux magic number exists & uImage CRC are correct.
If either of those conditions fail, a matching sys'n'_fail flag
is set in uboot env & a restart performed in the hope that the
alternate kernel is okay.
If neither kernel checksums ok and both are marked failed, system 2
is booted anyway.
Note uboot's tftp flash install writes the transferred
image to both kernel partitions.
Installation:
Similar to the Xiaomi MIR3G, we keep stock Xiaomi firmware in
kernel0 for ease of recovery, and install OpenWRT into kernel1 and
after.
The installation file for OpenWRT is a *squashfs-factory.bin file that
contains the kernel and a ubi partition. This is flashed as follows:
nvram set flag_try_sys1_failed=1
nvram set flag_try_sys2_failed=0
nvram commit
dd if=factory.bin bs=1M count=4 | mtd write - kernel1
dd if=factory.bin bs=1M skip=4 | mtd write - rootfs0
reboot
Reverting to stock:
The part of stock firmware we've kept in kernel0 allows us to run stock
recovery, which will re-flash stock firmware from a *.bin file on a USB.
For this we do the following:
fw_setenv flag_try_sys1_failed 0
fw_setenv flag_try_sys2_failed 1
reboot
After reboot the LED status light will blink red, at which point pressing
the 'reset' button will cause stock firmware to be installed from USB.
Issues:
OpenWRT currently does not have support for the MT7615 wifi chips. There is
ongoing work to add mt7615 support to the open source mt76 driver. Until that
support is in place, there are closed-source kernel modules that can be used.

Create Factory image
--------------------
As all installation methods require a U-Boot to be integrated into the
Image (and we do not ship one with the image) we are not able to create
an image in the OpenWRT build-process.
Download a TP-Link image from their Wesite and a OpenWRT sysupgrade
image for the device and build yourself a factory image like following:
TP-Link image: tpl.bin
OpenWRT sysupgrade image: owrt.bin
> dd if=tpl.bin of=boot.bin bs=131584 count=1
> cat owrt.bin >> boot.bin
Installing via Web-UI
---------------------
Upload the boot.bin via TP-Links firmware upgrade tool in the
web-interface.
Installing via Recovery
-----------------------
Activate Web-Recovery by beginning the upgrade Process with a
Firmware-Image from TP-Link. After starting the Firmware Upgrade,
wait ~3 seconds (When update status is switching to 0%), then
disconnect the power supply from the device. Upgrade flag (which
activates Web-Recovery) is written before the OS-image is touched and
removed after write is succesfull, so this procedure should be safe.
Plug the power back in. It will come up in Recovery-Mode on 192.168.0.1.
When active, all LEDs but the WPS LED are off.
Remeber to assign yourself a static IP-address as DHCP is not active in
this mode.
The boot.bin can now be uploaded and flashed using the web-recovery.
Installing via TFTP
-------------------
Prepare an image like following (Filenames from factory image steps
apply here)
> dd if=/dev/zero of=tp_recovery.bin bs=196608 count=1
> dd if=tpl.bin of=tmp.bin bs=131584 count=1
> dd if=tmp.bin of=boot.bin bs=512 skip=1
> cat boot.bin >> tp_recovery.bin
> cat owrt.bin >> tp_recovery.bin
Place tp_recovery.bin in root directory of TFTP server and listen on
192.168.0.66/24.
Connect router LAN ports with your computer and power up the router
while pressing the reset button. The router will download the image via
tftp and after ~1 Minute reboot into OpenWRT.
U-Boot CLI
----------
U-Boot CLI can be activated by holding down '4' on bootup.
Dual U-Boot
-----------
This is the first TP-Link MediaTek device to feature a split-uboot
design. The first (factory-uboot) provides recovery via TFTP and HTTP,
jumping straight into the second (firmware-uboot) if no recovery needs
to be performed. The firmware-uboot unpacks and executed the kernel.
Web-Recovery
------------
TP-Link integrated a new Web-Recovery like the one on the Archer C7v4 /
TL-WR1043v5. Stock-firmware sets a flag in the "romfile" partition
before beginning to write and removes it afterwards. If the router boots
with this flag set, bootloader will automatically start Web-recovery and
listens on 192.168.0.1. This way, the vendor-firmware or an OpenWRT
factory image can be written.
By doing the same while performing sysupgrade, we can take advantage of
the Web-recovery in OpenWRT.
It is important to note that Web-Recovery is only based on this flag. It
can't detect e.g. a crashing kernel or other means. Once activated it
won't boot the OS before a recovery action (either via TFTP or HTTP) is
performed. This recovery-mode is indicated by an illuminated WPS-LED on
boot.

Very similar to the DWR-921-C1, except has a telephony/RJ11 port (not
sure if supported, I didn't try), wireless router with QMI LTE embedded
modem is based on the MT7620N SoC.
Specification:
* MediaTek MT7620N (580 Mhz)
* 64 MB of RAM
* 16 MB of FLASH
* 802.11bgn radio
* 5x 10/100 Mbps Ethernet (1 WAN and 4 LAN)
* 2x external, detachable (LTE) antennas
* UART header on PCB (57600 8n1)
* 6x LED (GPIO-controlled)
* 1x bi-color Signal Strength LED (GPIO-controlled)
* 2x button
* JBOOT bootloader
The status led has been assigned to the dwr-922-e2:green:signalstrength
(lte signal strength) led. At the end of the boot it is switched off and
is available for lte operation. Works correctly also during sysupgrade
operation.
Installation:
Apply factory image via d-link http web-gui, or via recovery interface:
How to recover/revert to OEM firmware:
1.) Push and hold the reset button and turn on the power. Wait until all
LEDs start rapidly blinking (~10sec.)
2.) DHCP should give you an IP in the 192.168.123.0/24 subnet, or set
one manually
3.) Upload original factory image via JBOOT http interface at IP
192.168.123.254
4.) If http doesn't work, it can be done with curl command:
curl -F FN=@XXXXX.binhttp://192.168.123.254/upg
where XXXXX.bin is name of firmware file.
5.) You can optionally telnet to 192.168.123.254 before or during the
upload and it will report the flashing status, memory address etc.
6.) Once web UI and/or telnet says "Success", power cycle the router, or

Flashing instructions:
A) The U-Boot has HTTP based firmware upgrade
A1) Flashing notes
We've identified so far two different batches of units, unfortunately
each batch has different U-Boot bootloader flashed with different
default environment variables, thus each batch has different IP address
for accessing web based firmware updater.
* First batch has web based bootloader IP address 1.1.1.1
* Second batch has web based bootloader IP address 192.168.1.250
In case you can't connect to either of those IPs, you can try to get
the default IP address via two methods:
A1.1) Serial console, then the IP address is visible during the boot
...
HTTP server is starting at IP: 1.1.1.1
raspi_read: from:40004 len:6
HTTP server is ready!
...
A1.2) Over telnet/SSH using this command:
root@bdcom:/# grep ipaddr= /dev/mtd0
ipaddr=1.1.1.1
A2) Flashing with browser
* Change IP address of PC to 1.1.1.2 with 255.255.255.0 netmask
* Reboot the device and try to reach web based bootloader in the

The LEDs should be triggered/lit by any kind of state change instead of
turned on/off unconditional.
If LEDs really need to be turned off by default, it should be done via
the default-state devicetree led property.
The handling of the wndr3700v5 and wt3020 power led is at least
strange. Something is for sure wrong with them. Either the leds are
misnamed, the default off trigger is a typo or the polarity of the
gpios is wrong. Drop the power led from userspace and wait for someone
with access to the hardware to fix it properly.

- UART header on PCB
- Vcc, GND, TX, RX from ethernet port side
- baudrate: 115200 bps (U-Boot, OpenWrt)
Stock firmware:
In the stock firmware, WN-AX1167GR has two os images each composed of
Linux kernel and rootfs.
These images are stored in "Kernel" and "app" partition of the
following partitions, respectively.
(excerpt from dmesg):

Creating 10 MTD partitions on "raspi":
0x000000000000-0x000001000000 : "ALL"
0x000000000000-0x000000030000 : "Bootloader"

The flag for boot partition is stored in "Key" partition, and U-Boot
reads this and determines the partition to boot.
If the image that U-Boot first reads according to the flag is
"Bad Magic Number", U-Boot then tries to boot from the other image.
If the second image is correct, change the flag to the number
corresponding to that image and boot from that image.

This commit adds support for the MikroTik RouterBOARD RBM11g.
=Hardware=
The RBM11g is a mt7621 based device featuring one GbE port and one
miniPCIe slot with a sim card socket and USB 2.0.
==Switch==
The single onboard Ethernet port is connected the CPU directly.
The internal switch of the mt7621 SoC is disabled.
==Flash==
The device has one spi nor flash chip. It is a 128 Mbit winbond 25Q128FVS
connected to CS0.
==PCIe==
The board features a single miniPCIe slot. It has a dedicated mini SIM
socket and a USB 2.0 port. Power to the miniPCIe slot is controlled via
GPIO9.
==USB==
There are no external USB ports.
==Power==
The board can accept both, passive PoE and external power via a 2.1 mm
barrel jack (center-positive). The input voltage range is 11-32 V.
==Serial port==
The device does have an onboard UART on an unpopulated header next to the
flash chip:
GND: pin 2
TX: pin 7
RX: pin 6
Settings: 115200, 8N1
See below illustration for positioning of the header.
0 = screw hole

=Installation=
To install an OpenWRT image to the device two components must be built:
1. A openwrt initramfs image
2. A openwrt sysupgrade image
===initramfs & sysupgrade image===
Select target devices "Mikrotik RBM11G" in
openwrt menuconfig and build the images. This will create the images
"openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin" and
"openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin" in the
output directory.
==Installing==
**Make sure to back up your RouterOS license in case you do ever want to
go back to RouterOS using "/system license output" and back up the
created license file.**
When rebooted the board will try booting via ethernet first. If your
board does not boot via ethernet automatically you will have to attach
to the serial port and set ethernet as boot device within RouterBOOT.
1. Set up a dhcp server that points the bootfile to tftp server serving
the "openwrt-ramips-mt7621-mikrotik_rbm11g-initramfs-kernel.bin"
initramfs image
2. Connect to ethernet port on board
3. Power on the board
4. Wait for OpenWrt to boot
Right now OpenWrt will be running with a SSH server listening. Now
OpenWrt must be flashed to the devices flash:
1. Copy "openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
to the device using scp.
2. Write openwrt to flash using "sysupgrade
openwrt-ramips-mt7621-mikrotik_rbm11g-squashfs-sysupgrade.bin"
Once the flashing completes the board will reboot. Disconnect from the
devices ethernet port or stop the DHCP/TFTP server to prevent the device
from booting via ethernet again.
The device should now boot straight to OpenWrt.

Preparing a TFTP recovery image for initial flashing:
Currently the only method to install openwrt for the first time is via
TFTP download in u-boot. After first install you can use regular updates.
WARNING: This method also overwrites the bootloader partition!
Create a TFTP recovery image:
1) Download a stock TP-Link Firmware file here:
https://www.tp-link.com/en/download/Archer-C2_V1.html#Firmware
2) Extract u-boot from the binary file:
#> dd if=c2v1_stock_firmware.bin of=c2v1_uboot.bin bs=1 skip=512 count=131072
3) Now merge the sysupgrade image and the u-boot into one binary:
#> cat c2v1_uboot.bin openwrt-squashfs-sysupgrade.bin > ArcherC2V1_tp_recovery.bin
The resulting image can be flashed via TFTP recovery mode.
Flash instructions:
1) To flash the recovery image, start a TFTP server from IP address
192.168.0.66 and serve the recovery image named
ArcherC2V1_tp_recovery.bin.
2) Connect your device to the LAN port, then press the WPS/Reset button
and power it up. Keep pressing the WPS/Reset button for 10 seconds.
It will try to download the recovery image and flash it.

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.
