TP-Link Archer AX55 v1 is an IPQ5018 Wi-Fi 6 router.
Hardware:
SoC: Qualcomm IPQ5018 (dual Cortex-A53)
RAM: 512 MiB
Flash: 128 MiB SPI-NAND (dual firmware slots)
Switch: Realtek RTL8367S (5x GbE), 2.5G HSGMII trunk to gmac1
WiFi: IPQ5018 2.4 GHz + QCN6122 5 GHz (ath11k)
USB: 1x USB 3.0 port, SuperSpeed, using the IPQ5018 SS uni PHY;
the port's 5 V rail is a GPIO-switched regulator wired as the
PHY's vdd-supply, the way the MR5500 does it
Button: Reset, WPS/Wi-Fi
LED: power, LAN, WAN (green/orange), 2.4G, 5G, USB
All five front jacks are RTL8367S ports (DSA): blue "WAN" = wan,
LAN1-4 = lan1..lan4, over the 2.5G HSGMII trunk.
The factory MAC is the "default-mac" file in the tp_data UBIFS volume
(there is no raw nvmem cell for it). The volume is attached and mounted
read-only during preinit, so board.d assigns the wired MACs (label MAC
for lan/eth0, +1 for wan) the usual way and the ath11k caldata hotplug
derives the Wi-Fi MACs (+2/+3) from the same mount - the same scheme
the mt7981 archer-ax80-v1 uses for its tp_data. gmac1 has no nvmem MAC
source, so the DSA conduit is pinned to the label MAC in board.d to
keep it stable across boots.
The board data files live in firmware_qca-wireless, where they were
merged as f2c37a6b9d1d; this commit pins the ipq-wifi package to that
revision and adds the package entry for the board.
Note on revisions: some units labelled "v1" carry an RTL8367D-family
switch (chip id 0x6642) instead of the RTL8367S. rtl8365mb cleanly
declines it ("unrecognized switch"), so such a unit boots with no wired
ports, and with Wi-Fi off by default it is only reachable via the
vendor web recovery (or serial). RTL8367D support in rtl8365mb is being
worked on by others; until it lands the wiki page carries a prominent
warning to identify the switch before flashing. v2/v4 are entirely
different hardware and are not covered by this image.
Installation (serial console on the JP1 header, 115200 8N1, 1.8 V; note
the RX trace is gapped and must be bridged to type): interrupt U-Boot,
TFTP-boot the initramfs image to 0x44000000, "bootm", then "sysupgrade -n".
A serial-free path (a telnet-enabled resigned stock image flashed from the
vendor web UI, then writing the OpenWrt image to the inactive slot) is
documented on the device wiki page; that path consumes the
initramfs-factory.ubi artifact, which is the initramfs kernel wrapped in
a UBI image so it can be written straight into the inactive rootfs
partition with mtd from the running stock firmware.
Recovery to stock: hold Reset while powering on, set the PC to
192.168.0.10, and upload an official signed TP-Link image at
http://192.168.0.1.
