From cd2b661453a8a2b8260dfb9b9c0dc5297b981331 Mon Sep 17 00:00:00 2001 From: Andrew Pikler Date: Wed, 27 Jan 2021 19:35:49 +0200 Subject: [PATCH] ramips: add support for Cudy WR1300 Specifications: - SoC: MediaTek MT7621AT - RAM: 128 MB (DDR3) - Flash: 16 MB (SPI NOR) - WiFi: MediaTek MT7603E, MediaTek MT7612E - Switch: 1 WAN, 4 LAN (Gigabit) - Ports: 1 USB 3.0 - Buttons: Reset, WPS - LEDs: Power, System, Wan, Lan 1-4, WiFi 2.4G, WiFi 5G, WPS, USB - Power: DC 12V 1A tip positive UART Serial: 115200 baud Located on unpopulated 4 pin header near J4: J4 [o] Rx [o] Tx [o] GND [ ] Vcc - Do not connect Installation: Download and flash the manufacturer's built OpenWRT image available at http://www.cudytech.com/openwrt_software_download Install the new OpenWRT image via luci (System -> Backup/Flash firmware) Be sure to NOT keep settings. The force upgrade may need to be checked due to differences in router naming conventions. Recovery: - Loads only signed manufacture firmware due to bootloader RSA verification - serve tftp-recovery image as /recovery.bin on 192.168.1.88/24 - connect to any lan ethernet port - power on the device while holding the reset button - wait at least 8 seconds before releasing reset button for image to download - See http://www.cudytech.com/newsinfo/547425.html MAC addresses as verified by OEM firmware: use address source LAN *:f0 label WAN *:f1 label + 1 2g *:f0 label 5g *:f2 label + 2 The label MAC address is found in bdinfo 0xde00.
