From 45b51ebaff51d2a49d149e9011717abb1b032683 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Jakub=20Van=C4=9Bk?= Date: Mon, 2 Mar 2026 21:14:28 +0100 Subject: [PATCH] mediatek: filogic: add support for Cudy M3000 w/ YT8821 PHY MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The hardware is very close the the Cudy M3000 v1 (see commit 20e4a18feb3f). However, the Motorcomm YT8821 PHY is tricky to support because of a MDIO address collision within the router. Specification: - MT7981BA CPU: dual-core ARM Cortex-A53 @ 1.3 GHz - 256 MiB RAM - 128 MiB SPI NAND - Ethernet: - 1x 1GbE LAN port driven by the internal MT7981 PHY - 1x 2.5GbE WAN port driven by the Motorcomm YT8821 - WiFi: - MT7981BA 2.4 GHz WiFi with 2x2:2 MIMO - MT7981BA 5 GHz WiFi with 2x3:2 MIMO - Buttons: Reset, WPS - LED: 1x combined red/white How to know if you have the a router with the YT8821 PHY: - Boot the router into the vendor's firmware. Go to Diagnostic Tools -> System Log. Try searching for "rtl8221b". - If there are some matches, you have the Cudy M3000 router with the Realtek PHY and you should NOT use the device defined in this commit. Instead, you should use the device defined in mt7981b-cudy-m3000-v1.dts. - If there are no matches, try searching for "yt8821". If that matches something, you have the Cudy M3000 with the Motorcomm PHY and you should use this device tree (mt7981b-cudy-m3000-v2-yt8821.dts). - If even the yt8821 string did not match anything, then something is wrong. Rebooting the router might help (the system log would be refreshed). Installation via the Cudy web UI: - Download the signed intermediary firmware from https://drive.google.com/drive/folders/1BKVarlwlNxf7uJUtRhuMGUqeCa5KpMnj - Flash the intermediary firmware using the Cudy web UI - Connect a PC/laptop to the "1Gbps LAN" port - Open http://192.168.1.1 in your browser, log in (the password should be empty) - Flash your desired OpenWrt firmware via LuCI - The router should reboot into the desired firmware How to access UART (citing from 20e4a18feb3f): - remove rubber ring on the bottom - remove screws - pull up the cylinder, maybe help by push on an ethernet socket with a screwdriver - remove the (3) screws holding the board in the frame - remove the board from the frame to get to the screws for the silver, flat heat shield - remove the (3) screws holding the heat shield - solder UART pins to the back of the board - make sure to have the pins point out on side with the black, finned heat spread - the markings for the pins are going to be below the silver heat shield - Vcc is not needed - the UART parameters are 115200 baud, 8n1 Installation via UART (citing from 20e4a18feb3f): - attach an Ethernet cable to the "1Gbps LAN" port on the router - hold the reset button while powering the router - press CTRL-C or wait for the timeout to get to the U-Boot prompt - prepare a TFTP server on the network to supply ..-initramfs-kernel.bin - use 'tftpboot 0x46000000 ..-initramfs-kernel.bin' in the U-Boot shell to pull the image (change the file name accordingly) - boot the image using 'bootm 0x46000000' - push the ..-sysupgrade to the router using your preferred method - perform the upgrade with 'sysupgrade -n' Signed-off-by: Jakub VanÄ›k Link: https://github.com/openwrt/openwrt/pull/22259 Signed-off-by: Hauke Mehrtens --- .../lib/preinit/05_set_preinit_iface | 1 + .../mediatek/dts/mt7981b-cudy-m3000-v1.dts | 192 +---------------- .../dts/mt7981b-cudy-m3000-v2-yt8821.dts | 22 ++ .../mediatek/dts/mt7981b-cudy-m3000.dtsi | 195 ++++++++++++++++++ .../filogic/base-files/etc/board.d/02_network | 1 + .../etc/hotplug.d/ieee80211/11_fix_wifi_mac | 1 + target/linux/mediatek/image/filogic.mk | 22 ++ 7 files changed, 244 insertions(+), 190 deletions(-) create mode 100644 target/linux/mediatek/dts/mt7981b-cudy-m3000-v2-yt8821.dts create mode 100644 target/linux/mediatek/dts/mt7981b-cudy-m3000.dtsi diff --git a/target/linux/mediatek/base-files/lib/preinit/05_set_preinit_iface b/target/linux/mediatek/base-files/lib/preinit/05_set_preinit_iface index 174baa407d..40b9a926c2 100644 --- a/target/linux/mediatek/base-files/lib/preinit/05_set_preinit_iface +++ b/target/linux/mediatek/base-files/lib/preinit/05_set_preinit_iface @@ -2,6 +2,7 @@ set_preinit_iface() { case $(board_name) in bazis,ax3000wm|\ cudy,m3000-v1|\ + cudy,m3000-v2-yt8821|\ cudy,tr3000-256mb-v1|\ cudy,tr3000-v1|\ cudy,tr3000-v1-ubootmod|\ diff --git a/target/linux/mediatek/dts/mt7981b-cudy-m3000-v1.dts b/target/linux/mediatek/dts/mt7981b-cudy-m3000-v1.dts index 5cbd683418..05e7d57045 100644 --- a/target/linux/mediatek/dts/mt7981b-cudy-m3000-v1.dts +++ b/target/linux/mediatek/dts/mt7981b-cudy-m3000-v1.dts @@ -2,106 +2,15 @@ /dts-v1/;
