TP-Link RE700X is a dual-band Wi-Fi 6 (AX3000) range extender based on Qualcomm IPQ5018 (2.4 GHz) with a QCN6122 (5 GHz) companion radio. Specifications: - SoC: Qualcomm IPQ5018 (dual-core ARM Cortex-A53) - RAM: 256 MiB - Flash: 128 MiB SPI-NAND (ESMT F50D1G41LB) - Wi-Fi: IPQ5018 2.4 GHz + QCN6122 5 GHz, both 802.11ax - Ethernet: 1x Gigabit - IPQ5018 MAC1 (DWMAC) via SGMII/uniphy0 to a Realtek RTL8211F (MDIO1 addr 6). The SoC internal GE PHY (MAC0/gmac0) is not wired to any external port and stays disabled. - LEDs: 5, Buttons: reset + WPS - Power: 100-240 V AC, 50/60 Hz, 0.4 A (internal PSU, wall-plug) - UART: 3.3 V serial console, 115200 8N1; on-board 4-pad header, pinout from top: TX, RX, GND, VCC MAC addresses (factory_data UBI volume, file default-mac, mounted read-only in preinit like on the EAP650): - LAN (label MAC): default-mac - 2.4 GHz: default-mac + 1 - 5 GHz: default-mac + 2 Calibration data is extracted from the 0:art partition (IPQ5018 at 0x1000, QCN6122 at 0x26800). Installation: - From OpenWrt (or after a RAM-boot of the initramfs via U-Boot/TFTP): sysupgrade. - From the stock firmware: openwrt-...-squashfs-factory-webflash.bin via the TP-Link web UI (System -> Firmware Upgrade). scripts/tplink-re700x-factory.py wraps the rootfs UBI into the stock "nvrammanager" upload container (the same "tplink2022"/safeloader family as scripts/tplink-mkimage-2022.py); the stock flasher writes it into the inactive dual-boot slot. This path has not been tested end to end (no unit on stock firmware was left), so keep UART at hand for a first install. The stock U-Boot passes a slot-correct ubi.mtd= (rootfs / rootfs_1 per the dual-boot index) but with an unmountable root=mtd:ubi_rootfs. The DTS /chosen inherits ubi.mtd= and appends root=/dev/ubiblock0_1, so OpenWrt boots from whichever slot the flasher wrote. Like on the EAP650, sysupgrade installs into the inactive slot and then points tp_boot_idx at it, keeping the running slot as a fallback; the U-Boot environment is on 0:appsblenv. The QCN6122/IPQ5018 board-2.bin (BDF) data is supplied via ipq-wifi-tplink_re700x (openwrt/firmware_qca-wireless). Wi-Fi is disabled in the DTS for now: with the default ath11k DP ring sizes both radios exhaust the 256 MiB of RAM. It will be enabled in a follow-up together with the ath11k patch that selects smaller rings on low-memory boards, once that has been accepted upstream.
