It was reported, that Tenbay T-MB5EU v1 do have incorrect Wireless MAC
address set on 2.4 and 5 GHz.
Some boards do not seem to have the correct MAC address set for the
external PHY of the MT7915 radio at caldata offset 0xa.
As the external PHY does not expose a DT binding (yet), fix up the mac
address in userspace.

power, install the "poemgr" package from the packages feed.
This package can control the PD69104B1 PSE controller.
Installation
------------
1. Connect to the booted device at 192.168.1.20 using username/password
"ubnt" via SSH.
2. Add the uboot-envtools configuration file /etc/fw_env.config with the
following content
$ echo "/dev/mtd1 0x0 0x1000 0x10000 1" > /etc/fw_env.config
3. Update the bootloader environment.
$ fw_setenv boot_openwrt "fdt addr \$(fdtcontroladdr);
fdt rm /signature; bootubnt"
$ fw_setenv bootcmd "run boot_openwrt"
4. Transfer the OpenWrt sysupgrade image to the device using SCP.
5. Check the mtd partition number for bs / kernel0 / kernel1
$ cat /proc/mtd
6. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
7. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
8. Reboot the device. It should boot into OpenWrt.

Since increment is inconsistent and there is no obvious pattern

it seems safer to use the LAN address with flipped byte here in
order to prevent collisions between OpenWrt devices and OEM devices
for this interface. This way we at least use an address as base
that is definitely owned by the device at hand.

At the time of adding support the wireless config needs to be set up by
editing the wireless config file:
* Setting the country code is mandatory, otherwise the router loses
connectivity at the next reboot. This is mandatory and can be done
from luci. After setting the country code the router boots correctly.
A reset with the reset button will fix the issue and the user has to
reconfigure.
* This is minor since the 5g interface does not come up online although
it is not set as disabled. 2 options here:
1- Either run the "wifi" command. Can be added from LUCI in system -
startup - local startup and just add wifi above "exit 0".
2- Or add the serialize option in the wireless config file as shown
below. This one would work and bring both interfaces automatically
at every boot:
config wifi-device 'radio0'

This might fail due to the A/B nature of this device. When flashing, OEM
firmware writes over the non-booted partition. If booted from 'A',
flashing over 'B' won't work. To get around this, you should flash the
OEM image over itself. This will then boot the router from 'B' and
allow you to flash OpenWRT without problems.
Reverting to factory firmware:
Hard-reset the router three times to force it to boot from 'B.' This is
where the stock firmware resides. To remove any traces of OpenWRT from
your router simply flash the OEM image at this point.

UART on compute module (silkscreened / 115200n8)
The router itself is just a board with Power / USB / RJ-45 connectors
and DC/DC converters. The SoC and WiFi components are on a
daughterboard which connect using two M.2 connectors.
The compute module has the model number "T-CB1800K-DM2 V02" printed on
it. The main baord has "T-MB5EU V01" printed on it. This information
might be useful, as it's highly likely either of these two will be
reused in similar designs.
The router itself is sold as Tenbay T-MB5EU directly from the OEM as
well as "KuWFI AX1800 Smart WiFi 6 Eouter" on Amazon.de for ~50€ in a
slightly different case.
Installation
------------
A Tool for creating a factory image for the Vendor Web Interface can be
found here: https://github.com/blocktrron/t-mb5eu-v01-factory-creator/
As the OEM Firmware is just a modified LEDE 17.01, you can also access
failsafe mode via UART while the OS boots, by connecting to UART
and pressing "f" when prompted. The Router is reachable at
192.168.1.1 via root without password.
Transfer the OpenWrt sysupgrade image via scp and apply with sysupgrade
using the -n and -F flags.
Alternatively, the board can be flashed by attaching to the UART
console, interrupting the boot process by keeping "0" pressed while
attaching power.
Serve the OpenWrt initramfs using a TFTP server with address
192.168.1.66. Rename the initramfs to ax1800.bin.
Attach your TFTP server to one of the LAN ports. Execute the following
commands.
$ setenv ipaddr 192.168.1.67
$ setenv serverip 192.168.1.66
$ tftpboot 0x84000000 ax1800.bin
$ bootm
Wait for the device to boot. Then transfer the OpenWrt sysupgrade image
to the device using SCP and apply sysupgrade.

J1: pin1 (square pad, towards rear)=3.3V, pin2=RX,
pin3=GND, pin4=TX. Settings: 57600/8N1.
Note regarding dual system partitions
-------------------------------------
The vendor firmware and boot loader use a dual partition scheme. The boot
partition is decided by the bootImage U-boot environment variable: 0 for
the 1st partition, 1 for the 2nd.
OpenWrt does not support this scheme and will always use the first OS
partition. It will set bootImage to 0 during installation, making sure
the first partition is selected by the boot loader.
Also, because we can't be sure which partition is active to begin with, a
2-step flash process is used. We first flash an initramfs image, then
follow with a regular sysupgrade.
Installation:
Router (ALLY-R1900K)
1) Install the flashable initramfs image via the OEM web-interface.
(Alternatively, you can use the TFTP recovery method below.)
You can use WiFi or Ethernet.
The direct URL is: http://192.168.3.1/07_06_00_firmware.html
a. No login is needed, and you'll be in their setup wizard.
b. You might get a warning about not being connected to the Internet.
c. Towards the bottom of the page will be a section entitled "Or
Manually Upgrade Firmware from a File:" where you can manually choose
and upload a firmware file.
d: Click "Choose File", select the OpenWRT "initramfs" image and click
"Upload."
2) The Router will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
3) Log into LuCI as root; there is no password.
4) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
5) Complete the Installation by flashing a full OpenWRT image. Note:
you may use the sysupgrade command line tool in lieu of the UI if
you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Extender (ALLY-00X19K)
1) This device requires a TFTP recovery procedure to do an initial load
of OpenWRT. Start by configuring a computer as a TFTP client:
a. Install a TFTP client (server not necessary)
b. Configure an Ethernet interface to 192.168.1.x/24; don't use .1 or .6
c. Connect the Ethernet to the sole Ethernet port on the X19K.
2) Put the ALLY Extender in TFTP recovery mode.
a. Do this by pressing and holding the reset button on the bottom while
connecting the power.
b. As soon as the LED lights up green (roughly 2-3 seconds), release
the button.
3) Start the TFTP transfer of the Initramfs image from your setup machine.
For example, from Linux:
tftp -v -m binary 192.168.1.6 69 -c put initramfs.bin
4) The Extender will flash the OpenWrt initramfs image and reboot. After
booting, LuCI will be available on 192.168.1.1.
5) Log into LuCI as root; there is no password.
6) Optional (but recommended) is to backup the OEM firmware before
continuing; see process below.
7) Complete the Installation by flashing a full OpenWRT image. Note: you
may use the sysupgrade command line tool in lieu of the UI if you prefer.
a. Choose System -> Backup/Flash Firmware.
b. Click "Flash Image..." under "Flash new firmware image"
c. Click "Browse..." and then select the sysupgrade file.
d. Click Upload to upload the sysupgrade file.
e. Important: uncheck "Keep settings and retain the current
configuration" for this initial installation.
f. Click "Continue" to flash the firmware.
g. The device will reboot and OpenWRT is installed.
Backup the OEM Firmware:
-----------------------
There isn't any downloadable firmware for the ALLY devices on the Amped
Wireless web site. Reverting back to the OEM firmware is not possible
unless we have a backup of the original OEM firmware.
The OEM firmware may be stored on either /dev/mtd3 ("firmware") or
/dev/mtd6 ("oem"). We can't be sure which was overwritten with the
initramfs image, so backup both partitions to be safe.
1) Once logged into LuCI, navigate to System -> Backup/Flash Firmware.
2) Under "Save mtdblock contents," first select "firmware" and click
"Save mtdblock" to download the image.
3) Repeat the process, but select "oem" from the pull-down menu.
Revert to the OEM Firmware:
--------------------------
* U-boot TFTP:
Follow the TFTP recovery steps for the Extender, and use the
backup image.
* OpenWrt "Flash Firmware" interface:
Upload the backup image and select "Force update"
before continuing.

Installation:
Flash factory image through GUI.
This device has 2 partitions for the firmware called firmware and
alt_firmware. To successfully flash and boot the device, the device
should have been running from alt_firmware partition. To get the device
booted through alt_firmware partition, download the OEM firmware from
Linksys website and upgrade the firmware from web GUI. Once this is done,
flash the OpenWrt Factory firmware from web GUI.
Reverting to factory firmware:
1. Boot to 'alt_firmware'(where stock firmware resides) by doing one of
the following:
Press the "wps" button as soon as power LED turns on when booting.
(OR) Hard-reset the router consecutively three times to force it to
boot from 'alt_firmware'.
2. To remove any traces of OpenWRT from your router simply flash the OEM
image at this point.

This patch adds support for TP-Link Archer C6U v1 (EU).
The device is also known in some market as Archer C6 v3.
This patch supports only Archer C6U v1 (EU).
Specifications:
--------------
* SoC: Mediatek MT7621AT 2C2T, 880MHz
* RAM: 128MB DDR3
* Flash: 16MB SPI NOR flash (Winbond 25Q128)
* WiFi 5GHz: Mediatek MT7613BEN (2x2:2)

* Buttons: Reset, WPS.
* UART: Serial console (115200 8n1), J1(GND:3)
* USB: One USB2 port.
Installation:
------------
Install the OpenWrt factory image for C6U is from the
TP-Link web interface.
1) Go to "Advanced/System Tools/Firmware Update".
2) Click "Browse" and upload the OpenWrt factory image:
openwrt-ramips-mt7621-tplink_archer-c6u-v1-squashfs-factory.bin.
3) Click the "Upgrade" button, and select "Yes" when prompted.
Recovery to stock firmware:
--------------------------
The C6U bootloader has a failsafe mode that provides a web
interface (running at 192.168.0.1) for reverting back to the
stock TP-Link firmware. The failsafe interface is triggered
from the serial console or on failed kernel boot. Unfortunately,
there's no key combination that enables the failsafe mode. This
gives us two options for recovery:
1) Recover using the serial console (J1 header).
The recovery interface can be selected by hitting 'x' when
prompted on boot.
2) Trigger the bootloader failsafe mode.
A more dangerous option is force the bootloader into
recovery mode by erasing the OpenWrt partition from the
OpenWrt's shell - e.g "mtd erase firmware". Please be
careful, since erasing the wrong partition can brick
your device.

WARNING!!
ISP managed firmware might at any time update itself to a version
where all known workarounds have been disabled. Never boot an ISP
managed firmware with a SIM in any of the slots if you intend to use
the router with OpenWrt. The bootloader lock can only be disabled with
root access to running firmware. The flash chip is physically
inaccessible without soldering.
Installation from OEM web GUI:
- Log in as "supervisor" on https://172.17.1.1/
- Upload OpenWrt initramfs-recovery.bin image on the
Maintenance -> Firmware page
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Installation from OEM ssh:
- Log in as "root" on 172.17.1.1 port 22022
- scp OpenWrt initramfs-recovery.bin image to 172.17.1.1:/tmp
- Prepare bootloader config by running:
nvram setro uboot DebugFlag 0x1
nvram setro uboot CheckBypass 0
nvram commit
- Run "mtd_write -w write initramfs-recovery.bin Kernel" and reboot
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- (optional) Copy OpenWrt to the recovery partition. See below
- Sysupgrade to the OpenWrt sysupgrade image and reboot
Copying OpenWrt to the recovery partition:
- Verify that you are running a working OpenWrt recovery image
from flash
- ssh to root@192.168.1.1 and run:
fw_setenv CheckBypass 0
mtd -r erase Kernel2
- Wait while the bootloader mirrors Image1 to Image2
NOTE: This should only be done after successfully booting the OpenWrt
recovery image from the primary partition during installation. Do
not do this after having sysupgraded OpenWrt! Reinstalling the
recovery image on normal upgrades is not required or recommended.
Installation from Z-Loader:
- Halt boot by pressing Escape on console
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Type "ATNR 1,initramfs-recovery.bin" at the "ZLB>" prompt
- Wait for OpenWrt to boot and ssh to root@192.168.1.1
- Sysupgrade to the OpenWrt sysupgrade image
NOTE: ATNR will write the recovery image to both primary and recovery
partitions in one go.
Booting from RAM:
- Halt boot by pressing Escape on console
- Type "ATGU" at the "ZLB>" prompt to enter the U-Boot menu
- Press "4" to select "4: Entr boot command line interface."
- Set up a tftp server to serve the OpenWrt initramfs-recovery.bin
image at 10.10.10.3
- Load it using "tftpboot 0x88000000 initramfs-recovery.bin"
- Boot with "bootm 0x8800017C" to skip the 380 (0x17C) bytes ZyXEL
header
This method can also be used to RAM boot OEM firmware. The warning
regarding OEM applies! Never boot an unknown OEM firmware, or any OEM
firmware with a SIM in any slot.
NOTE: U-Boot configuration is incomplete (on some devices?). You may
have to configure a working mac address before running tftp using
"setenv eth0addr <mac>"
Unlocking the bootloader:
If you are unebale to halt boot, then the bootloader is locked.
The OEM firmware locks the bootloader on every boot by setting
DebugFlag to 0. Setting it to 1 is therefore only temporary
when OEM firmware is installed.
- Run "nvram setro uboot DebugFlag 0x1; nvram commit" in OEM firmware
- Run "fw_setenv DebugFlag 0x1" in OpenWrt
NOTE:
OpenWrt does this automatically on first boot if necessary
NOTE2:
Setting the flag to 0x1 avoids the reset to 0 in known OEM
versions, but this might change.
WARNING:
Writing anything to flash while the bootloader is locked is
considered extremely risky. Errors might cause a permanent
brick!
Enabling management access from LAN:
Temporary workaround to allow installing OpenWrt if OEM firmware
has disabled LAN management:
- Connect to console
- Log in as "root"
- Run "iptables -I INPUT -i br0 -j ACCEPT"
Notes on the OEM/bootloader dual partition scheme
The dual partition scheme on this device uses Image2 as a recovery
image only. The device will always boot from Image1, but the
bootloader might copy Image2 to Image1 under specific conditions. This
scheme prevents repurposing of the space occupied by Image2 in any
useful way.
Validation of primary and recovery images is controlled by the
variables CheckBypass, Image1Stable, and Image1Try.
The bootloader sets CheckBypass to 0 and reboots if Image1 fails
validation.
If CheckBypass is 0 and Image1 is invalid then Image2 is copied to
Image1.
If CheckBypass is 0 and Image2 is invalid, then Image1 is copied to
Image2.
If CheckBypass is 1 then all tests are skipped and Image1 is booted
unconditionally. CheckBypass is set to 1 after each successful
validation of Image1.
Image1Try is incremented if Image1Stable is 0, and Image2 is copied to
Image1 if Image1Try is 3 or larger. But the bootloader only tests
Image1Try if CheckBypass is 0, which is impossible unless the booted
image sets it to 0 before failing.
The system is therefore not resilient against runtime errors like
failure to mount the rootfs, unless the kernel image sets CheckBypass
to 0 before failing. This is not yet implemented in OpenWrt.
Setting Image1Stable to 1 prevents the bootloader from updating
Image1Try on every boot, saving unnecessary writes to the environment
partition.
Keeping an OpenWrt initramfs recovery as Image2 is recommended
primarily to avoid unwanted OEM firmware boots on failure. Ref the
warning above. It enables console-less recovery in case of some
failures to boot from Image1.

The TP-Link EAP235-Wall is a wall-mounted, PoE-powered AC1200 access
point with four gigabit ethernet ports.
When connecting to the device's serial port, it is strongly advised to
use an isolated UART adapter. This prevents linking different power
domains created by the PoE power supply, which may damage your devices.
The device's U-Boot supports saving modified environments with
`saveenv`. However, there is no u-boot-env partition, and saving
modifications will cause the partition table to be overwritten. This is
not an issue for running OpenWrt, but will prevent the vendor FW from
functioning properly.
Device specifications:
* SoC: MT7621DAT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Wireless 2.4GHz (MT7603EN): b/g/n, 2x2
* Wireless 5GHz (MT7613BEN): a/n/ac, 2x2
* Ethernet: 4× GbE
* Back side: ETH0, PoE PD port
* Bottom side: ETH1, ETH2, ETH3
* Single white device LED
* LED button, reset button (available for failsafe)
* PoE pass-through on port ETH3 (enabled with GPIO)
Datasheet of the flash chip specifies a maximum frequency of 33MHz, but
that didn't work. 20MHz gives no errors with reading (flash dump) or
writing (sysupgrade).
Device mac addresses:
Stock firmware uses the same MAC address for ethernet (on device label)
and 2.4GHz wireless. The 5GHz wireless address is incremented by one.
This address is stored in the 'info' ('default-mac') partition at an
offset of 8 bytes.
From OEM ifconfig:
eth a4:2b:b0:...:88
ra0 a4:2b:b0:...:88
rai0 a4:2b:b0:...:89
Flashing instructions:
* Enable SSH in the web interface, and SSH into the target device
* run `cliclientd stopcs`, this should return "success"
* upload the factory image via the web interface
Debricking:
U-boot can be interrupted during boot, serial console is 57600 baud, 8n1
This allows installing a sysupgrade image, or fixing the device in
another way.
* Access serial header from the side of the board, close to ETH3,
pin-out is (1:TX, 2:RX, 3:GND, 4:3.3V), with pin 1 closest to ETH3.
* Interrupt bootloader by holding '4' during boot, which drops the
bootloader into its shell
* Change default 'serverip' and 'ipaddr' variables (optional)
* Download initramfs with `tftpboot`, and boot image with `bootm`
# tftpboot 84000000 openwrt-initramfs.bin
# bootm
Revert to stock:
Using the tplink-safeloader utility from the firmware-utils package,
TP-Link's firmware image can be converted to an OpenWrt-compatible

$ ./staging_dir/host/bin/tplink-safeloader -B EAP235-WALL-V1 \
-z EAP235-WALLv1_XXX_up_signed.bin -o eap235-sysupgrade.bin
This can then be flashed using the OpenWrt sysupgrade interface. The
image will appear to be incompatible and must be force flashed, without
keeping the current configuration.
Known issues:
- DFS support is incomplete (known issue with MT7613)
- MT7613 radio may stop responding when idling, reboot required.

$ cat /proc/mtd
5. Set the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtdblock4
6. Write the OpenWrt sysupgrade image to both kernel0 as well as kernel1
$ dd if=openwrt.bin of=/dev/mtdblock6
$ dd if=openwrt.bin of=/dev/mtdblock7
7. Reboot the device. It should boot into OpenWrt.
Below are the original installation instructions prior to the discovery
of "devmode=TRUE". They are not required for installation and are
documentation only.
The bootloader employs signature verification on the FIT image
configurations. This way, booting unauthorized image without patching
the bootloader is not possible. Manually configuring the bootcmd in the
U-Boot envronment won't work, as this is restored to the default value
if modified.
The bootloader is made up of three different parts.
1. The SPL performing early board initialization and providing a XModem
recovery in case the PBL is missing
2. The PBL being the primary U-Boot application and containing the
control FDT. It is LZMA packed with a uImage header.
3. A Ubiquiti standalone U-Boot application providing the main boot
routine as well as their recovery mechanism.
In a perfect world, we would only replace the PBL, as the SPL does not
perform checks on the PBLs integrity. However, as the PBL is in the same
eraseblock as the SPL, we need to at least rewrite both.
The bootloader will only verify integrity in case it has a "signature"
node in it's control device-tree. Renaming the signature node to
something else will prevent this from happening.
Warning: These instructions are based on the firmware intially
shipped with the device and potentially brick your device in a way it
can only be recovered using a SPI flasher.
Only (!) proceed if you understand this!
1. Extract the bootloader from the U-Boot partition using the OpenWrt
initramfs image.
2. Split the bootloader into it's 3 components:
$ dd if=bootloader.bin of=spl.bin bs=1 skip=0 count=45056
$ dd if=bootloader.bin of=pbl.uimage bs=1 skip=45056 count=143360
$ dd if=bootloader.bin of=ubnt.uimage bs=1 skip=188416
3. Strip the uImage header from the PBL
$ dd if=pbl.uimage of=pbl.lzma bs=64 skip=1
4. Decompress the PBL
$ lzma -d pbl.lzma --single-stream
The decompressed PBL sha256sum should be
d8b406c65240d260cf15be5f97f40c1d6d1b6e61ec3abed37bb841c90fcc1235
5. Open the decompressed PBL using your favorite hexeditor. Locate the
control FDT at offset 0x4CED0 (0xD00DFEED). At offset 0x4D5BC, the
label for the signature node is located. Rename the "signature"
string at this offset to "signaturr".
The patched PBL sha256sum should be
d028e374cdb40ba44b6e3cef2e4e8a8c16a3b85eb15d9544d24fdd10eed64c97
6. Compress the patched PBL
$ lzma -z pbl --lzma1=dict=67108864
The resulting pbl.lzma file should have the sha256sum
7ae6118928fa0d0b3fe4ff81abd80ecfd9ba2944cb0f0a462b6ae65913088b42
7. Create the PBL uimage
$ SOURCE_DATE_EPOCH=1607909492 mkimage -A mips -O u-boot -C lzma
-n "U-Boot 2018.03 [UniFi,v1.1.40.71]" -a 84000000 -e 84000000
-T firmware -d pbl.lzma patched_pbl.uimage
The resulting patched_pbl.uimage should have the sha256sum
b90d7fa2dcc6814180d3943530d8d6b0d6a03636113c94e99af34f196d3cf2ce
8. Reassemble the complete bootloader
$ dd if=patched_pbl.uimage of=aligned_pbl.uimage bs=143360 count=1
conv=sync
$ cat spl.bin > patched_uboot.bin
$ cat aligned_pbl.uimage >> patched_uboot.bin
$ cat ubnt.uimage >> patched_uboot.bin
The resulting patched_uboot.bin should have the sha256sum
3e1186f33b88a525687285c2a8b22e8786787b31d4648b8eee66c672222aa76b
9. Transfer your patched bootloader to the device. Also install the
kmod-mtd-rw package using opkg and load it.
$ insmod mtd-rw.ko i_want_a_brick=1
Write the patched bootloader to mtd0
$ mtd write patched_uboot.bin u-boot
10. Erase the kernel1 partition, as the bootloader might otherwise
decide to boot from there.
$ mtd erase kernel1
11. Transfer the OpenWrt sysupgrade image to the device and install
using sysupgrade.
