From fea2264d9fddc285f724aad04335462807710d61 Mon Sep 17 00:00:00 2001 From: Mauri Sandberg Date: Mon, 31 Jul 2023 15:35:46 +0300 Subject: [PATCH] ramips: mt7621: Add DNA Valokuitu Plus EX400 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Specifications: - Device: DNA Valokuitu Plus EX400 - SoC: MT7621A - Flash: 256MB NAND - RAM: 256MB - Ethernet: Built-in, 2 x 1GbE - Wifi: MT7603 2.4 GHz, MT7615 5 GHz (4x internal antennas) - USB: 1x 3.0 - LED: 1x green/red, 1x green - Buttons: Reset MAC addresses: - LAN: u-boot 'ethaddr' (label) - WAN: label + 1 - 2.4 GHz: label + 6 - 5 GHz: label + 7 Serial: There is a black block connector next to the red ethernet connector. It is accessible also through holes in the casing. Pinout (TTL 3.3V) +---+---+ |Tx |Rx | +---+---+ |Vcc|Gnd| +---+---+ Firmware: The vendor firmware is a fork of OpenWrt (Reboot) with a kernel version 4.4.93. The flash is arranged as below and there is a dual boot mechanism alternating between rootfs_0 and rootfs_1. +-------+------+------+-----------+-----------+ | | env1 | env2 | rootfs_0 | rootfs_1 | | +------+------+-----------+-----------+ | | UBI volumes | +-------+-------------------------------------+ |U-Boot | UBI | +-------+-------------------------------------+ |mtd0 | mtd1 | +-------+-------------------------------------+ | NAND | +---------------------------------------------+ In OpenWrt rootfs_0 will be used as a boot partition that will contain the kernel and the dtb. The squashfs rootfs and overlay are standard OpenWrt behaviour. +-------+------+------+-----------+--------+------------+ | | env1 | env2 | rootfs_0 | rootfs | rootfs_data| | +------+------+-----------+--------+------------+ | | UBI volumes | +-------+-----------------------------------------------+ |U-Boot | UBI | +-------+-----------------------------------------------+ |mtd0 | mtd1 | +-------+-----------------------------------------------+ | NAND | +-------------------------------------------------------+ U-boot: With proper serial access booting can be halted to U-boot by pressing any key. TFTP and flash writes are available, but only the first one has been tested. NOTE: Recovery mode can be accessed by holding down the reset button while powering on the device. The led 'Update' will show a solid green light once ready. A web server will be running at 192.168.1.1:80 and it will allow flashing a firmware package. You can cycle between rootfs_0 and rootfs_1 by pressing the reset button once. Root password: With the vendor web UI create a backup of your settings and download the archive to your computer. Within the archive in the file /etc/shadow replace the password hash for root with that of a password you know. Restore the configuration with the vendor web UI and you will have changed the root password. SSH access: You might need to enable the SSH service for LAN interface as by default it's enabled for WAN only. Installing OpenWrt: With the vendor web UI install the OpenWrt factory image. Alternatively, ssh to the device and use sysupgrade -n from cli. Finalize by installing the OpenWrt sysupgrade image to get a fully functioning system. Reverting to the vendor firmware: Boot with OpenWrt initramfs image - Remove volumes rootfs_0, rootfs and rootfs_data and create vendor volumes. ubirmvol /dev/ubi0 -n 2 ubirmvol /dev/ubi0 -n 3 ubirmvol /dev/ubi0 -n 4 ubimkvol /dev/ubi0 -N rootfs_0 -S 990 ubimkvol /dev/ubi0 -N rootfs_1 -S 990 Power off and enter to the U-boot recovery to install the vendor firmware. Known issues: - MACs for wifi are stored in currently unknown place but it seems to persist over power-off. They might be stored on the chip.
