1. Create "rootfs_data" dynamicaly
U-Boot firmware images can contain only 2 UBI volumes: bootfs (container
with U-Boot + kernel + DTBs) and rootfs (e.g. squashfs). There is no way
to include "rootfs_data" UBI volume or make firmware file tell U-Boot to
create one.
For that reason "rootfs_data" needs to be created dynamically. Use
preinit script to handle that. Fire it right before "mount_root" one.
2. Relate "rootfs_data" to flashed firmware
As already explained flashing new firmware with U-Boot will do nothing
to the "rootfs_data". It could result in new firmware reusing old
"rootfs_data" overlay UBI volume and its file. Users expect a clean
state after flashing firmware (even if flashing the same one).
Solve that by reading flash counter of running firmware and storing it
in "rootfs_data" UBI volume. Every mismatch will result in wiping old
data.

TP-Link Archer A9 v6 (FCCID: TE7A9V6) is an AC1900 Wave-2 gigabit home
router based on a combination of Qualcomm QCN5502 (most likely a 4x4:4
version of the QCA9563 WiSOC), QCA9984 and QCA8337N.
The vendor's firmware content reveals that the same device might be
available on the US market under name 'Archer C90 v6'. Due to lack of
access to such hardware, support introduced in this commit was tested
only on the EU version (sold under 'Archer A9 v6' name).
Based on the information on the PL version of the vendor website, this
device has been already phased out and is no longer available.
Specifications:
- Qualcomm QCN5502 (775 MHz)
- 128 MB of RAM (DDR2)
- 16 MB of flash (SPI NOR)
- 5x Gbps Ethernet (Qualcomm QCA8337N over SGMII)
- Wi-Fi:
- 802.11b/g/n on 2.4 GHz: Qualcomm QCN5502* in 4x4:4 mode
- 802.11a/n/ac on 5 GHz: Qualcomm QCA9984 in 3x3:3 mode
- 3x non-detachable, dual-band external antennas (~3.5 dBi for 5 GHz,
~2.2 dBi for 2.4 GHz, IPEX/U.FL connectors)
- 1x internal PCB antenna for 2.4 GHz (~1.8 dBi)
- 1x USB 2.0 Type-A
- 11x LED (4x connected to QCA8337N, 7x connected to QCN5502)
- 2x button (reset, WPS)
- UART (4-pin, 2.54 mm pitch) header on PCB (not populated)
- 1x mechanical power switch
- 1x DC jack (12 V)
*) unsupported due to missing support for QCN550x in ath9k
UART system serial console notice:
The RX signal of the main SOC's UART on this device is shared with the
WPS button's GPIO. The first-stage U-Boot by default disables the RX,
resulting in a non-functional UART input.
If you press and keep 'ENTER' on the serial console during early
boot-up, the first-stage U-Boot will enable RX input.
Vendor firmware allows password-less access to the system over serial.
Flash instruction (vendor GUI):
1. It is recommended to first upgrade vendor firmware to the latest
version (1.1.1 Build 20210315 rel.40637 at the time of writing).
2. Use the 'factory' image directly in the vendor's GUI.
Flash instruction (TFTP based recovery in second-stage U-Boot):
1. Rename 'factory' image to 'ArcherA9v6_tp_recovery.bin'
2. Setup a TFTP server on your PC with IP 192.168.0.66/24.
3. Press and hold the reset button for ~5 sec while turning on power.
4. The device will download image, flash it and reboot.
Flash instruction (web based recovery in first-stage U-Boot):
1. Use 'CTRL+C' during power-up to enable CLI in first-stage U-Boot.
2. Connect a PC with IP set to 192.168.0.1 to one of the LAN ports.
3. Issue 'httpd' command and visit http://192.168.0.1 in browser.
4. Use the 'factory' image.
If you would like to restore vendor's firmware, follow one of the
recovery methods described above.

Add support for the TP-Link EAP615-Wall, an AX1800 Wall Plate WiFi 6 AP.
The device is very similar to the TP-Link EAP235-Wall.
Hardware:
* SoC: MediaTek MT7621AT
* RAM: 128MiB
* Flash: 16MiB SPI-NOR
* Ethernet: 4x GbE
* Back: ETH0 (PoE-PD)
* Bottom: ETH1, ETH2, ETH3 (PoE passthrough)
* WiFi: MT7905DAN/MT7975DN 2.4/5 GHz 2T2R
* LEDS: 1x white
* Buttons: 1x LED, 1x reset
Stock firmware uses a random MAC address for ethernet. OpenWrt uses the
MAC address that is on the device label for ethernet and the wireless
interfaces. MAC address must not be incremented, as this will cause MAC
address conflicts in case you have two devices with consecutive MAC
addresses. Instead, different locally administered addresses will be
generated automatically, based on the MAC on the label.
Installation via stock firmware:
* Enable SSH in the TP-Link web interface
* SSH to the device
* Run `cliclientd stopcs`
* Upload the OpenWrt factory image via the TP-Link web interface
Installation via bootloader:
* Solder TTL header. Pinout: 1: TX, 2: RX, 3: GND, 4: VCC, with pin 1
closest to ETH1. Baud rate 115200
* Interrupt boot process by holding a key during boot
* Boot the OpenWrt initramfs:
# tftpboot 0x84000000 openwrt-ramips-mt7621-tplink_eap615-wall-v1-initramfs-kernel.bin
# bootm
* Copy openwrt-ramips-mt7621-tplink_eap615-wall-v1-squashfs-sysupgrade.bin
to /tmp and use sysupgrade to install it

The device shares many components with previous model, MF286, differing
mostly by a Wave2 5GHz radio, flash layout and internal LED color.
In case of MF286A, the modem is the same as in MF286. MF286R uses a
different modem based on Marvell PXA1826 chip.
Internal modem of MF286A is supported via uqmi, MF286R modem isn't fully
supported, but it is expected to use comgt-ncm for connection, as it
uses standard 3GPP AT commands for connection establishment.
Console connection: connector X2 is the console port, with the following
pinout, starting from pin 1, which is the topmost pin when the board is
upright:
- VCC (3.3V). Do not use unless you need to source power for the
converer from it.
- TX
- RX
- GND
Default port configuration in U-boot as well as in stock firmware is
115200-8-N-1.
Installation:
Due to different flash layout from stock firmware, sysupgrade from
within stock firmware is impossible, despite it's based on QSDK which
itself is based on OpenWrt.
STEP 0: Stock firmware update:
As installing OpenWrt cuts you off from official firmware updates for
the modem part, it is recommended to update the stock firmware to latest
version before installation, to have built-in modem at the latest firmware
version.
STEP 1: gaining root shell:
Method 1:
This works if busybox has telnetd compiled in the binary.
If this does not work, try method 2.
Using well-known exploit to start telnetd on your router - works
only if Busybox on stock firmware has telnetd included:
- Open stock firmware web interface
- Navigate to "URL filtering" section by going to "Advanced settings",
then "Firewall" and finally "URL filter".
- Add an entry ending with "&&telnetd&&", for example
"http://hostname/&&telnetd&&".
- telnetd will immediately listen on port 4719.
- After connecting to telnetd use "admin/admin" as credentials.
Method 2:
This works if busybox does not have telnetd compiled in. Notably, this
is the case in DNA.fi firmware.
If this does not work, try method 3.
- Set IP of your computer to 192.168.0.22. (or appropriate subnet if
changed)
- Have a TFTP server running at that address
- Download MIPS build of busybox including telnetd, for example from:
https://busybox.net/downloads/binaries/1.21.1/busybox-mips
and put it in it's root directory. Rename it as "telnetd".
- As previously, login to router's web UI and navigate to "URL
filtering"
- Using "Inspect" feature, extend "maxlength" property of the input
field named "addURLFilter", so it looks like this:
<input type="text" name="addURLFilter" id="addURLFilter" maxlength="332"
class="required form-control">
- Stay on the page - do not navigate anywhere
- Enter "http://aa&zte_debug.sh 192.168.0.22 telnetd" as a filter.
- Save the settings. This will download the telnetd binary over tftp and
execute it. You should be able to log in at port 23, using
"admin/admin" as credentials.
Method 3:
If the above doesn't work, use the serial console - it exposes root shell
directly without need for login. Some stock firmwares, notably one from
finnish DNA operator lack telnetd in their builds.
STEP 2: Backing up original software:
As the stock firmware may be customized by the carrier and is not
officially available in the Internet, IT IS IMPERATIVE to back up the
stock firmware, if you ever plan to returning to stock firmware.
It is highly recommended to perform backup using both methods, to avoid
hassle of reassembling firmware images in future, if a restore is
needed.
Method 1: after booting OpenWrt initramfs image via TFTP:
PLEASE NOTE: YOU CANNOT DO THIS IF USING INTERMEDIATE FIRMWARE FOR INSTALLATION.
- Dump stock firmware located on stock kernel and ubi partitions:
ssh root@192.168.1.1: cat /dev/mtd4 > mtd4_kernel.bin
ssh root@192.168.1.1: cat /dev/mtd9 > mtd9_ubi.bin
And keep them in a safe place, should a restore be needed in future.
Method 2: using stock firmware:
- Connect an external USB drive formatted with FAT or ext4 to the USB
port.
- The drive will be auto-mounted to /var/usb_disk
- Check the flash layout of the device:
cat /proc/mtd
It should show the following:
mtd0: 000a0000 00010000 "u-boot"
mtd1: 00020000 00010000 "u-boot-env"
mtd2: 00140000 00010000 "reserved1"
mtd3: 000a0000 00020000 "fota-flag"
mtd4: 00080000 00020000 "art"
mtd5: 00080000 00020000 "mac"
mtd6: 000c0000 00020000 "reserved2"
mtd7: 00400000 00020000 "cfg-param"
mtd8: 00400000 00020000 "log"
mtd9: 000a0000 00020000 "oops"
mtd10: 00500000 00020000 "reserved3"
mtd11: 00800000 00020000 "web"
mtd12: 00300000 00020000 "kernel"
mtd13: 01a00000 00020000 "rootfs"
mtd14: 01900000 00020000 "data"
mtd15: 03200000 00020000 "fota"
mtd16: 01d00000 00020000 "firmware"
Differences might indicate that this is NOT a MF286A device but
one of other variants.
- Copy over all MTD partitions, for example by executing the following:
for i in 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15; do cat /dev/mtd$i > \
/var/usb_disk/mtd$i; done
"Firmware" partition can be skipped, it is a concatenation
of "kernel" and "rootfs".
- If the count of MTD partitions is different, this might indicate that
this is not a MF286A device, but one of its other variants.
- (optionally) rename the files according to MTD partition names from
/proc/mtd
- Unmount the filesystem:
umount /var/usb_disk; sync
and then remove the drive.
- Store the files in safe place if you ever plan to return to stock
firmware. This is especially important, because stock firmware for
this device is not available officially, and is usually customized by
the mobile providers.
STEP 3: Booting initramfs image:
Method 1: using serial console (RECOMMENDED):
- Have TFTP server running, exposing the OpenWrt initramfs image, and
set your computer's IP address as 192.168.0.22. This is the default
expected by U-boot. You may wish to change that, and alter later
commands accordingly.
- Connect the serial console if you haven't done so already,
- Interrupt boot sequence by pressing any key in U-boot when prompted
- Use the following commands to boot OpenWrt initramfs through TFTP:
setenv serverip 192.168.0.22
setenv ipaddr 192.168.0.1
tftpboot 0x81000000 openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin
bootm 0x81000000
(Replace server IP and router IP as needed). There is no emergency
TFTP boot sequence triggered by buttons, contrary to MF283+.
- When OpenWrt initramfs finishes booting, proceed to actual
installation.
Method 2: using initramfs image as temporary boot kernel
This exploits the fact, that kernel and rootfs MTD devices are
consecutive on NAND flash, so from within stock image, an initramfs can
be written to this area and booted by U-boot on next reboot, because it
uses "nboot" command which isn't limited by kernel partition size.
- Download the initramfs-kernel.bin image
- After backing up the previous MTD contents, write the images to the
"firmware" MTD device, which conveniently concatenates "kernel" and
"rootfs" partitions that can fit the initramfs image:
nandwrite -p /dev/<firmware-mtd> \
/var/usb_disk/openwrt-ath79-zte_mf286a-initramfs-kernel.bin
- If write is OK, reboot the device, it will reboot to OpenWrt
initramfs:
reboot -f
- After rebooting, SSH into the device and use sysupgrade to perform
proper installation.
Method 3: using built-in TFTP recovery (LAST RESORT):
- With that method, ensure you have complete backup of system's NAND
flash first. It involves deliberately erasing the kernel.
- Download "-initramfs-kernel.bin" image for the device.
- Prepare the recovery image by prepending 8MB of zeroes to the image,
and name it root_uImage:
dd if=/dev/zero of=padding.bin bs=8M count=1
cat padding.bin openwrt-ath79-nand-zte_mf286a-initramfs-kernel.bin >
root_uImage
- Set up a TFTP server at 192.0.0.1/8. Router will use random address
from that range.
- Put the previously generated "root_uImage" into TFTP server root
directory.
- Deliberately erase "kernel" partition" using stock firmware after
taking backup. THIS IS POINT OF NO RETURN.
- Restart the device. U-boot will attempt flashing the recovery
initramfs image, which will let you perform actual installation using
sysupgrade. This might take a considerable time, sometimes the router
doesn't establish Ethernet link properly right after booting. Be
patient.
- After U-boot finishes flashing, the LEDs of switch ports will all
light up. At this moment, perform power-on reset, and wait for OpenWrt
initramfs to finish booting. Then proceed to actual installation.
STEP 4: Actual installation:
- Set your computer IP to 192.168.1.22/24
- scp the sysupgrade image to the device:
scp openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin \
root@192.168.1.1:/tmp/
- ssh into the device and execute sysupgrade:
sysupgrade -n /tmp/openwrt-ath79-nand-zte_mf286a-squashfs-sysupgrade.bin
- Wait for router to reboot to full OpenWrt.
STEP 5: WAN connection establishment
Since the router is equipped with LTE modem as its main WAN interface, it
might be useful to connect to the Internet right away after
installation. To do so, please put the following entries in
/etc/config/network, replacing the specific configuration entries with
one needed for your ISP:
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth '<auth>' # As required, usually 'none'
option pincode '<pin>' # If required by SIM
option apn '<apn>' # As required by ISP
option pdptype '<pdp>' # Typically 'ipv4', or 'ipv4v6' or 'ipv6'
For example, the following works for most polish ISPs
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
option auth 'none'
option apn 'internet'
option pdptype 'ipv4'
The required minimum is:
config interface 'wan'
option proto 'qmi'
option device '/dev/cdc-wdm0'
In this case, the modem will use last configured APN from stock
firmware - this should work out of the box, unless your SIM requires
PIN which can't be switched off.
If you have build with LuCI, installing luci-proto-qmi helps with this
task.
Restoring the stock firmware:
Preparation:
If you took your backup using stock firmware, you will need to
reassemble the partitions into images to be restored onto the flash. The
layout might differ from ISP to ISP, this example is based on generic stock
firmware
The only partitions you really care about are "web", "kernel", and
"rootfs". These are required to restore the stock firmware through
factory TFTP recovery.
Because kernel partition was enlarged, compared to stock
firmware, the kernel and rootfs MTDs don't align anymore, and you need
to carve out required data if you only have backup from stock FW:
- Prepare kernel image
cat mtd12_kernel.bin mtd13_rootfs.bin > owrt_kernel.bin
truncate -s 4M owrt_kernel_restore.bin
- Cut off first 1MB from rootfs
dd if=mtd13_rootfs.bin of=owrt_rootfs.bin bs=1M skip=1
- Prepare image to write to "ubi" meta-partition:
cat mtd6_reserved2.bi mtd7_cfg-param.bin mtd8_log.bin mtd9_oops.bin \
mtd10_reserved3.bin mtd11_web.bin owrt_rootfs.bin > \
owrt_ubi_ubi_restore.bin
You can skip the "fota" partition altogether,
it is used only for stock firmware update purposes and can be overwritten
safely anyway. The same is true for "data" partition which on my device
was found to be unused at all. Restoring mtd5_cfg-param.bin will restore
the stock firmware configuration you had before.
Method 1: Using initramfs:
This method is recmmended if you took your backup from within OpenWrt
initramfs, as the reassembly is not needed.
- Boot to initramfs as in step 3:
- Completely detach ubi0 partition using ubidetach /dev/ubi0_0
- Look up the kernel and ubi partitions in /proc/mtd
- Copy over the stock kernel image using scp to /tmp
- Erase kernel and restore stock kernel:
(scp mtd4_kernel.bin root@192.168.1.1:/tmp/)
mtd write <kernel_mtd> mtd4_kernel.bin
rm mtd4_kernel.bin
- Copy over the stock partition backups one-by-one using scp to /tmp, and
restore them individually. Otherwise you might run out of space in
tmpfs:
(scp mtd3_ubiconcat0.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat0_mtd> mtd3_ubiconcat0.bin
rm mtd3_ubiconcat0.bin
(scp mtd5_ubiconcat1.bin root@192.168.1.1:/tmp/)
mtd write <ubiconcat1_mtd> mtd5_ubiconcat1.bin
rm mtd5_ubiconcat1.bin
- If the write was correct, force a device reboot with
reboot -f
Method 2: Using live OpenWrt system (NOT RECOMMENDED):
- Prepare a USB flash drive contatining MTD backup files
- Ensure you have kmod-usb-storage and filesystem driver installed for
your drive
- Mount your flash drive
mkdir /tmp/usb
mount /dev/sda1 /tmp/usb
- Remount your UBI volume at /overlay to R/O
mount -o remount,ro /overlay
- Write back the kernel and ubi partitions from USB drive
cd /tmp/usb
mtd write mtd4_kernel.bin /dev/<kernel_mtd>
mtd write mtd9_ubi.bin /dev/<kernel_ubi>
- If everything went well, force a device reboot with
reboot -f
Last image may be truncated a bit due to lack of space in RAM, but this will happen over "fota"
MTD partition which may be safely erased after reboot anyway.
Method 3: using built-in TFTP recovery:
This method is recommended if you took backups using stock firmware.
- Assemble a recovery rootfs image from backup of stock partitions by
concatenating "web", "kernel", "rootfs" images dumped from the device,
as "root_uImage"
- Use it in place of "root_uImage" recovery initramfs image as in the
TFTP pre-installation method.
Quirks and known issuesa
- It was observed, that CH340-based USB-UART converters output garbage
during U-boot phase of system boot. At least CP2102 is known to work
properly.
- Kernel partition size is increased to 4MB compared to stock 3MB, to
accomodate future kernel updates - at this moment OpenWrt 5.10 kernel
image is at 2.5MB which is dangerously close to the limit. This has no
effect on booting the system - but keep that in mind when reassembling
an image to restore stock firmware.
- uqmi seems to be unable to change APN manually, so please use the one
you used before in stock firmware first. If you need to change it,
please use protocok '3g' to establish connection once, or use the
following command to change APN (and optionally IP type) manually:
echo -ne 'AT+CGDCONT=1,"IP","<apn>' > /dev/ttyUSB0
- The only usable LED as a "system LED" is the blue debug LED hidden
inside the case. All other LEDs are controlled by modem, on which the
router part has some influence only on Wi-Fi LED.
- Wi-Fi LED currently doesn't work while under OpenWrt, despite having
correct GPIO mapping. All other LEDs are controlled by modem,
including this one in stock firmware. GPIO19, mapped there only acts
as a gate, while the actual signal source seems to be 5GHz Wi-Fi
radio, however it seems it is not the LED exposed by ath10k as
ath10k-phy0.
- GPIO5 used for modem reset is a suicide switch, causing a hardware
reset of whole board, not only the modem. It is attached to
gpio-restart driver, to restart the modem on reboot as well, to ensure
QMI connectivity after reboot, which tends to fail otherwise.
- Modem, as in MF283+, exposes root shell over ADB - while not needed
for OpenWrt operation at all - have fun lurking around.
The same modem module is used as in older MF286.

Package the ability to log kernel crashes to 'ramoops' pstore
files into RAM in /sys/fs/pstore
Reference to the ramoops admin guide in upstream Linux:
https://www.kernel.org/doc/html/v5.10/admin-guide/ramoops.html
The files in RAM survive a warm reboot, but not a cold reboot.
Note: kmod-ramoops selects kmod-pstore and kmod-reed-solomon.
The feature can be used by selecting the kmod-ramoops and
adding a ramoops reserved-memory definition to the device DTS.
Example from R7800:
reserved-memory {
rsvd@5fe00000 {
reg = <0x5fe00000 0x200000>;
reusable;
};
ramoops@42100000 {
compatible = "ramoops";
reg = <0x42100000 0x40000>;
record-size = <0x4000>;
console-size = <0x4000>;
ftrace-size = <0x4000>;
pmsg-size = <0x4000>;
};
};
If no definition has been made in DTS, no crash log is stored
for the device.

Previously, grub2 was hardcoded to always look on "hd0" for the
kernel.
This works well when the system only had a single disk.
But if there was a second disk/stick present, it may have look
on the wrong drive because of enumeration races.
This patch utilizes grub2 search function to look for a filesystem
with the label "kernel". This works thanks to existing setup in
scripts/gen_image_generic.sh. Which sets the "kernel" label on
both the fat and ext4 filesystem variants.

The I/O base address for the timers was hardcoded into the driver,
or derived from the HW IRQ number as an even more horrible hack. All
supported SoC families have these timers, but with hardcoded addresses
the code cannot be reused right now.
Request the timer's base address from the DT specification, and store it
in a private struct for future reference.
Matching the second interrupt specifier, the address range for the
second timer is added to the DT specification.

The Realtek timer node for RTL930x doesn't have any child nodes, making
the use of '#address-cells' quite pointless. It is also not an interrupt
controller, meaning it makes no sense to define '#interrupt-cells'.
The I/O address for this node is also wrong, but this is hidden by the
fact that the driver associated with this node bypasses the usual DT
machinery and does it's own thing. Correct the address to have a sane
value, even though it isn't actually used.

The assigned output index for the event timers was quite low, lower even
than the ethernet interrupt. This means that high network load could
preempt timer interrupts, possibly leading to all sorts of strange
behaviour.
Increase the interrupt output index of the event timers to 5, which is
the highest priority output and corresponds to the (otherwise unused)
MIPS CPU timer interrupt.
