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.

This adjusts the Makefile to use the new option to turn off the
doc builds. It will not cause any problems except a warning
about unused options if combined with a ccache source missing

Since a config setting is required to re-enable the doc build this
is equivalent to unconditionally disabling the docs if the config

The ZyXEL NR7101 prepend an additional header to U-Boot images. This
header use the TRX magic 0x30524448 (HDR0), but is incompatible with
TRX images.
This code is reverse-engineered based on matching 32 bit numbers
found in the header with lengths and different checksum
calculations of the vendor images found on the device. The result
was matched against the validation output produced by the
bootloader to name the associated header fields.
Example bootloader validation output:
Zyxel TRX Image 1 --> Found! Header Checksum OK
============ZyXEL header information==================
chipId : MT7621A
boardId : NR7101
modelId : 07 01 00 01
kernel_len : (14177560)
kernelChksum : (0x8DD31F69)
swVersionInt : 1.00(ABUV.0)D1
swVersionExt : 1.00(ABUV.0)D1
Zyxel TRX Image 2 --> Found! Header Checksum OK
============ZyXEL header information==================
chipId : MT7621A
boardId : NR7101
modelId : 07 01 00 01
kernel_len : (14176660)
kernelChksum : (0x951A7637)
swVersionInt : 1.00(ABUV.0)D0
swVersionExt : 1.00(ABUV.0)D0
=================================================
Check image validation:
Image1 Header Magic Number --> OK
Image2 Header Magic Number --> OK
Image1 Header Checksum --> OK
Image2 Header Checksum --> OK
Image1 Data Checksum --> OK
Image2 Data Checksum --> OK
Image1 Stable Flag --> Stable
Image1 Try Counter --> 0
Image1: OK
Image2: OK
The coverage and algorithm for the kernelChksum field is unknown.
This field is not validated by the bootloader or the OEM firmware
upgrade tool. It is therefore set to a static value for now.
The swVersion fields contain free form string values. The OEM firmware
use ZyXEL structured version numbers as shown above. The strings are
not interpreted or validated on boot, so they can be repurposed for
anything we want the bootloader to display to the user. But the OEM
web GUI fails to flash images with freeform strings.
The purpose of the other strings in the header is not known. The
values appear to be static. We assume they are fixed for now, until
we have other examples. One of these strings is the platform name,
which is taken as an input parameter for support other members of
the device family.

The old code didn't make sense as it was using "len" variable which was
guaranteed to be always 0. Loop right above broken code is:
while (len > 0) { }
With this recent ALIGN macro fix this resulted in subtracting block size
from 0 and calling write_out_padding() with a negative length.
To calculate amount of bytes needed for padding & alignment it should be
enough to use % 4.

Currently it's not possible to flash factory images on devices shipped
with vendor firmware versions 1.1.0 Build 20201120 rel. 50406 (published
2020-12-22):
(curFw_ver, newFw_ver) == (1.1, 1.0) [NM_Error](nm_checkSoftVer) 00848: Firmwave not supports, check failed.
[NM_Error](nm_checkUpdateContent) 01084: software version dismatched
[NM_Error](nm_buildUpgradeStruct) 01188: checkUpdateContent failed.
They've even following note in release notes:
Note: You will be unable to downgrade to the previous firmware version
after updating this firmware.
This version check in vendor firmware is implemented in
/usr/bin/nvrammanager binary likely as following C code[1]:
sscanf(buf, "%d.%d.%*s",&upd_fw_major, &upd_fw_minor);
...
if (((int)upd_fw_major < (int)cur_fw_major) ||
((ret = 1, cur_fw_major == upd_fw_major && (upd_fw_minor < (int)cur_fw_minor)))) {
ret = 0;
printf("[NM_Error](%s) %05d: Firmwave not supports, check failed.\r\n\r\n","nm_checkSoftVer" ,0x350);
}
...
return ret;
So in order to fix this and make it future proof it should be enough to
ship our factory firmware images with major version 7 (lucky number).
Tested on latest firmware version 1.1.2 Build 20210125 rel.37999:

This old ELF library dating to 2009 used to be necessary on MacOS but
is not required for building the kernel or tools since [1]. On Linux
systems, libelf is already an OpenWRT build-system prerequisite [2].
Presence of the older library can mask or conflict with the system libelf
and lead to build errors, as seen compiling Linux kernels since v5.8 or
host tools such as dwarves (e.g. pahole).
Remove the unnecessary tools/libelf library and avoid the related issues.

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
sysupgrade image:
$ ./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.
This was an issue with the ddc75ff704 version of mt76, but appears to
have improved/disappeared with bc3963764d.
