>From 8caba6e68210b46b93b42c88cb3b1b6ae6273b07 Mon Sep 17 00:00:00 2001 From: Ivan Lee <[email protected]> Date: Sat, 20 Jun 2026 15:45:00 +0800 Subject: [PATCH 3/3] ramips: add support for Dragonglass DGR7
Dragonglass DGR7 is an MT7621 based dual-band router. Specifications: - SoC: MediaTek MT7621A (880 MHz) - RAM: 128 MB DDR2 - Flash: 16 MB SPI NOR (XM25QH128A) - WiFi: MT7603E (2.4 GHz) + MT7612E (5 GHz, AC1200) - Ethernet: 5x 1GbE via MT7530 DSA switch (port 0-3 = LAN, port 4 = WAN) - LED: green status (GPIO 15, active low) - Button: reset (GPIO 18, active low) - Serial: 57600 8N1 - Flash layout: kernel uImage at 0xa0000 Installation: - Boot the initramfs image over U-Boot TFTP - Run sysupgrade with the squashfs sysupgrade image The on-flash XM25QH128A needs the XMC SPI-NOR block protection support added in the preceding commit so that sysupgrade is able to erase the firmware partition.
