From c13a050d5ad55ab090a592823a9f964af8614fc2 Mon Sep 17 00:00:00 2001 From: Roland Reinl Date: Wed, 12 Mar 2025 19:11:08 +0100 Subject: [PATCH] ramips: Add support for Cudy M1200 v1 The M1200 v1 is similar to the TR1200 series from Cudy. Differences: - Only 1 LAN port - No USB Specifications: - MT7628 - MT7628AN (2.4G b/g/n) and MT7613BE (5G ac/n) wifi - 128 MB RAM - 16 MB flash MAC Addresses: - There is one on the label, e.g. xx:xx:xx:xx:xx:A4 - LAN (bottom connector) is the same as the label, e.g. xx:xx:xx:xx:xx:A4 - WAN (top connector) is label + 1, e.g. xx:xx:xx:xx:xx:A5 - WLAN (2.4G) is the same as the label, e.g. xx:xx:xx:xx:xx:A4 - WLAN (5G) is label + 2, e.g. xx:xx:xx:xx:xx:A6 UART: - is available via the pin holes on the board - The pinout is printed to the board: P: VCC, G: GND, R: RX, T:TX - RX and TX require solder bridges to be installed - Do NOT connect VCC - Settings: 3.3V, 115200, 8N1 GPIO: - There are two LEDs: Red (GPIO 4) and White (GPIO 0) - There are two buttons: Reset (GPIO 11) and WPS (GPIO 5) Migration to OpenWrt: - Download the migration image from the Cudy website (it should be available as soon as OpenWrt officially supports the device) - Connect computer to LAN (bottom connector) and flash the migration image via OEM web interface - OpenWrt is now accessible via 192.168.1.1 Revert back to OEM firmware: - Set up a TFTP server on IP 192.168.1.88 and connect to the WAN port (upper port) - Provide the Cudy firmware as recovery.bin in the TFTP server - Press the reset button while powering on the device - Recovery process is started now - When recovery process is done, OEM firmware is accessible via 192.168.10.1 again General information: - No possibility to load a initramfs image via U-Boot because there is no option to interrupt U-Boot Signed-off-by: Roland Reinl Link: https://github.com/openwrt/openwrt/pull/18233 Signed-off-by: Hauke Mehrtens --- .../ramips/dts/mt7628an_cudy_m1200-v1.dts | 187 ++++++++++++++++++ target/linux/ramips/image/mt76x8.mk | 11 ++ .../mt76x8/base-files/etc/board.d/02_network | 1 + 3 files changed, 199 insertions(+) create mode 100644 target/linux/ramips/dts/mt7628an_cudy_m1200-v1.dts diff --git a/target/linux/ramips/dts/mt7628an_cudy_m1200-v1.dts b/target/linux/ramips/dts/mt7628an_cudy_m1200-v1.dts new file mode 100644 index 00000000000..05721d99849 --- /dev/null +++ b/target/linux/ramips/dts/mt7628an_cudy_m1200-v1.dts @@ -0,0 +1,187 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "mt7628an.dtsi" + +#include +#include +#include + +/ { + compatible = "cudy,m1200-v1", "mediatek,mt7628an-soc";
