From 7d74ef4b85568a29658f623d621cd3091becc98e Mon Sep 17 00:00:00 2001 From: Sander van Deijck Date: Sat, 15 Feb 2025 23:06:08 +0100 Subject: [PATCH] ramips: mt7621: add support for Arcadyan WE410443 The Arcadyan WE410443 is a WiFi AC access point distributed by various ISPs under various names, including KPN SuperWifi and BT Whole Home Wi-Fi. It features one ethernet port, dual MT7615N radios and four internal antennas. Hardware: - SoC: Mediatek MT7621AT - Flash: 32 MB - RAM: 128 MB - Ethernet: 1x 10/100/1000 Mbps, built into the SoC - WLAN: 2x MediaTek MT7615N - Buttons: 1 Reset button, 1 WPS button - LEDs: 1x Green, 1x Blue, 1x Red, all unmarked - Power: 12 VDC, 1.5A barrel plug Installation: The bootloader is locked with a password, so the image needs to be written directly to the SPI flash chip. To do this, you need to open up the case, remove the heatsink and connect the flash chip to a Raspberry Pi. Use the following connections: Flash chip --> Raspberry Pi VCC --> 3v3 RESET --> 3v3 /CS --> GPIO 8 DO --> GPIO 9 CLK --> GPIO 11 DI --> GPIO 10 GND --> Ground You can solder wires to the flash chip, or use a SOIC16 clip. More details on the Raspberry Pi and SPI chip pinouts are available on the wiki [1] When you have the Raspberry Pi connected to the flash chip, boot your Pi and follow the instructions: 1) Make sure your Pi has SPI enabled with sudo raspi-config 2) Install necessary tools: sudo apt install xxd libubootenv-tool mtd-utils 3) Upload overlay and execute: sudo dtc -@ -I dts -O dtb -o /boot/overlays/we410443.dtbo we410443-overlay.dts 4) Enable in /boot/firmware/config.txt by adding a new line containing dtoverlay=we410443 5) Reboot your Pi and verify the mtd partitions with cat /proc/mtd, you should see: dev: size erasesize name mtd0: 02000000 00001000 "all" mtd1: 00030000 00001000 "u-boot" mtd2: 00010000 00001000 "u-boot-env" mtd3: 00010000 00001000 "factory" mtd4: 01f60000 00001000 "firmware" mtd5: 00010000 00001000 "glbcfg" mtd6: 00010000 00001000 "config" mtd7: 00010000 00001000 "glbcfg2" mtd8: 00010000 00001000 "config2" 6) Optionally (but recommended), make a backup: sudo dd if=/dev/mtd0 of=backup.bin It can be restored with: sudo flashcp backup.bin /dev/mtd0 7) Set the variables for the bootloader: echo '/dev/mtd2 0x0 0x1000 0x1000' > fw_env.config sudo fw_setenv -c fw_env.config bootpartition 0 8) Finally, flash the image: sudo flashcp openwrt-ramips-mt7621-arcadyan_we410443- squashfs-sysupgrade.bin /dev/mtd4 MAC addresses The label address is stored in ASCII in the config partition Use --> Address Device --> label Ethernet --> label WLAN 2g --> + 1 WLAN 5g --> + 2 References: [1] https://openwrt.org/toh/arcadyan/astoria/we410443 Signed-off-by: Sander van Deijck Link: https://github.com/openwrt/openwrt/pull/17981 (cherry picked from commit b6a07dd0914e17d923f08c38fbfd4fa63fb2883b) Link: https://github.com/openwrt/openwrt/pull/19068 Signed-off-by: Hauke Mehrtens --- .../ramips/dts/mt7621_arcadyan_we410443.dts | 197 ++++++++++++++++++ target/linux/ramips/image/mt7621.mk | 17 ++ .../mt7621/base-files/etc/board.d/02_network | 5 + .../etc/hotplug.d/ieee80211/10_fix_wifi_mac | 7 + 4 files changed, 226 insertions(+) create mode 100755 target/linux/ramips/dts/mt7621_arcadyan_we410443.dts diff --git a/target/linux/ramips/dts/mt7621_arcadyan_we410443.dts b/target/linux/ramips/dts/mt7621_arcadyan_we410443.dts new file mode 100755 index 00000000000..ddcf37fdb03 --- /dev/null +++ b/target/linux/ramips/dts/mt7621_arcadyan_we410443.dts @@ -0,0 +1,197 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "mt7621.dtsi" + +#include +#include +#include + +/ { + model = "Arcadyan WE410443";
