From 577f3fdbc92c91e252ee3b134637816a240d89f7 Mon Sep 17 00:00:00 2001 From: David Yang Date: Sun, 6 Jun 2021 22:42:49 +0800 Subject: [PATCH] ramips: add support for Netcore NW5212 This patch adds support for Netcore NW5212, provided by some carrier in China. Specifications: -------------- * SoC: Mediatek MT7620A * RAM: 128MB DDR2 * Flash: 16MB SPI NOR flash (Winbond W25Q128BV) * WiFi 2.4GHz: builtin * Ethernet: builtin * LED: Power, WAN, LAN 1-4, WiFi * Buttons: Reset (GPIO 13) * UART: Serial console (57600 8n1) * USB: 1 x USB2 Installation: ------------ The router comes with OpenWrt 14.07 built with MTK SDK. However, as the modem is provided by carriers, so the web interface is highly minimized and only contains a static page with no interaction options. There are two possible ways to gain the access. 1) Open the shell and use a UART2USB convert to gain TTY access. Please notice you have to remove resistance R54 at the back of the board otherwise you won't be able to input anything. 2) Use built-in backdoor. Access http://192.168.1.1/cgi-bin/_/testxst to start dropbear service at port 9122. Be warned the software is super old and only diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, kexguess2@matt.ucc.asn.au is support, you may not be able to connect it with an up-to-date ssh client. After you can control the device, flash the firmware as usual. Here are some hints for that. Option 1 (via original firmware): 1) Setup HTTP server on your computer, for example: python3 -m http.server 2) Connect to the route and flash: cd /tmp wget http:/// mtd -r write firmware Option 2 (replacing u-boot via breed): 1) Download breed-mt7620-reset13.bin from https://breed.hackpascal.net/ 2) Setup HTTP server on your computer, for example: python3 -m http.server You can skip this step if your breed is already accessible from HTTP, since the original wget does not support HTTPS. 3) Connect to the route and flash breed: cd /tmp wget http:///breed-mt7620-reset13.bin mtd write breed-mt7620-reset13.bin Bootloader 4) Reboot. Hold reset key or press any key in TTY to enter breed. 5) Access breed web interface (http://192.168.1.1/). Choose the flash layout to be 0x50000 and flash new firmware. MAC addresses: ------------- There are three MACs stored in factory, as in MT7620A reference design: source address usage 0x4 label WLAN 0x28 label MAC 1 0x2e label + 1 MAC 2 However, the OEM firmware only uses one single MAC (label) for all interfaces, probably a misconfiguration.
