Installation
There are two known options:
1) The Luci-based UI.
2) Press and hold the reset button during power up.
The router will request 'recovery.bin' from a TFTP server at
192.168.1.88.
Both options require a signed firmware binary.
The openwrt image supplied by cudy is signed and can be used to
install unsigned images.
R4 & R5 need to be shorted (0-100Ω) for the UART to work.

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)
* WiFi 2.4GHz: Mediatek MT7603EN (2x2:2)
* Ethernet: MT7630, 5x 1000Base-T.
* LED: Power, WAN, LAN, WiFi 2GHz and 5GHz, USB
* 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.

The ZyXEL NR7101 is an 802.3at PoE powered 5G outdoor (IP68) CPE
with integrated directional 5G/LTE antennas.
Specifications:
- SoC: MediaTek MT7621AT
- RAM: 256 MB
- Flash: 128 MB MB NAND (MX30LF1G18AC)
- WiFi: MediaTek MT7603E
- Switch: 1 LAN port (Gigabiti)
- 5G/LTE: Quectel RG502Q-EA connected by USB3 to SoC
- SIM: 2 micro-SIM slots under transparent cover
- Buttons: Reset, WLAN under same cover
- LEDs: Multicolour green/red/yellow under same cover (visible)
- Power: 802.3at PoE via LAN port
The device is built as an outdoor ethernet to 5G/LTE bridge or
router. The Wifi interface is intended for installation and/or
temporary management purposes only.
UART Serial:
57600N1
Located on populated 5 pin header J5:
[o] GND
[ ] key - no pin
[o] RX
[o] TX
[o] 3.3V Vcc
Remove the SIM/button/LED cover, the WLAN button and 12 screws
holding the back plate and antenna cover together. The GPS antenna
is fixed to the cover, so be careful with the cable. Remove 4
screws fixing the antenna board to the main board, again being
careful with the cables.
A bluetooth TTL adapter is recommended for permanent console
access, to keep the router water and dustproof. The 3.3V pin is
able to power such an adapter.

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.

ath79, lantiq, ipq40xx, ramips all use the OpenWrt-specific gpio-export
functionality. Consolidate the patch that adds it under hack-5.10 since
this logic is obviously not target-specific. For those who want to
disable it, unsetting CONFIG_GPIO_SYSFS symbol will disable this code.
