From 9241f29c0eed40d16f7eb913ef3514e59a0f704c Mon Sep 17 00:00:00 2001 From: Vladimir Epifantsev Date: Sat, 6 Sep 2025 20:01:34 +0300 Subject: [PATCH] mediatek: filogic: add Keenetic Sprinter (KN-3711) support Specification: SoC: Mediatek MT7981BA RAM: 512 MB DDR4 RAM Flash: Winbond W25N01GV 128 MB SPI-NAND (dual boot on OEM) WiFi: MT7976CN DBDC AX Switch: MediaTek MT7531AE (3x LAN Gigabit ports) + Internal Gbe Phy (1x WAN Gigabit port) GPIO: 4x LED (power, internet, fn, wifi), 2x buttons (wps, reset), 1x switch (mesh) UART Interface: Pins: VCC, TX, RX, NC, GND Settings: 115200, 8N1 Flashing via TFTP: 1. Connect your PC and router to the first LAN port, configure PC interface using IP 192.168.1.2, mask 255.255.255.0 2. Save the factory image of the OpenWRT firmware, renamed to KN-3711_recovery.bin, on the TFTP server 3. Hold the reset button and power up the device 4. Keep the button pressed until the status LED starts blinking Signed-off-by: Vladimir Epifantsev Link: https://github.com/openwrt/openwrt/pull/19633 Signed-off-by: Hauke Mehrtens --- .../mediatek/dts/mt7981b-keenetic-kn-3711.dts | 329 ++++++++++++++++++ .../filogic/base-files/etc/board.d/02_network | 1 + .../etc/hotplug.d/ieee80211/11_fix_wifi_mac | 1 + target/linux/mediatek/image/filogic.mk | 20 ++ 4 files changed, 351 insertions(+) create mode 100755 target/linux/mediatek/dts/mt7981b-keenetic-kn-3711.dts diff --git a/target/linux/mediatek/dts/mt7981b-keenetic-kn-3711.dts b/target/linux/mediatek/dts/mt7981b-keenetic-kn-3711.dts new file mode 100755 index 0000000000..f18483542c --- /dev/null +++ b/target/linux/mediatek/dts/mt7981b-keenetic-kn-3711.dts @@ -0,0 +1,329 @@ +// SPDX-License-Identifier: GPL-2.0-only OR MIT + +/dts-v1/;
