From e497c975d3719e1d09f169cad33f95cea0b396b6 Mon Sep 17 00:00:00 2001 From: Daniel Golle Date: Wed, 14 Aug 2024 19:21:06 +0100 Subject: [PATCH] ramips: mt76x8: add support for Yuncore M300 Hardware: - SoC: MediaTek MT7628DAN (MIPS 580MHz) - Flash: 8 MiB Spansion S25FL064K - RAM: 64 MiB (built-into SoC) - WLAN: 2.4 GHz (MT7628) - Ethernet: 1x 10/100 Mbps WAN, 1x 10/100 LAN (MT7628) - Buttons: 1 Reset button - LEDs: 1x Red, 1x Green - Serial console: unpopulated header, 57600 8n1 (RX only) - Power: 12 VDC, 1 A There are unpopulated areas on the board for 5 GHz WiFi via PCIe as well as (most likely) Quectel EG25-G 4G module. As both are not populated on my board support for both is missing for now. Installation: The installation can be done via the recovery HTTP server which is built into the bootloader. Hold down the reset button while connecting the device to power and keep holding a bit more than 3 seconds. Connect to http://192.168.188.253/ and upload sysupgrade.bin file.
