From 51b653de94e7e5006b5480df33d5dfd9de824cc7 Mon Sep 17 00:00:00 2001 From: Georgi Vlaev Date: Tue, 25 Aug 2020 11:26:21 +0300 Subject: [PATCH] ramips: add support for Wavlink WL-WN531A6 This patch adds support for Wavlink WL-WN531A6 (Quantum D6). Specifications: -------------- * SoC: Mediatek MT7621AT 2C2T, 880MHz * RAM: 128MB DDR3, Nanya NT5CB64M16GP-EK * Flash: 16MB SPI NOR flash, GigaDevice GD25Q127CSIG * WiFi 5GHz: Mediatek MT7615N (4x4:4) on mini PCIE slot. * WiFi 2.4GHz: Mediatek MT7603EN (2x2:2) on mini PCIE slot. * Ethernet: MT7630, 5x 1000Base-T * LED: Power, WAN, LAN(x4), WiFi, WPS, dual color "WAVLINK" LED logo on the top cover. * Buttons: Reset, WPS, "Turbo", touch button on the top cover via RH6015C touch sensor. * UART: UART1: serial console (57600 8n1) on the J4 header located below the top heatsink. UART2: J12 header, located on the right side of the board. * USB: One USB3 port. * I2C: J9 header, located below the top heatsink. Backup the OEM Firmware: ----------------------- There isn't any firmware released for the WL-WN531A6 on the Wavlink web site. Reverting back to the OEM firmware is not possible unless we have a backup of the original OEM firmware. The OEM firmware is stored on /dev/mtd4 ("Kernel"). 1) Plug a FAT32 formatted USB flash drive into the USB port. 2) Navigate to "Setup->USB Storage". Under the "Available Network folder" you can see part of the mount point of the newly mounted flash drive filesystem - e.g "sda1". The full mount point is prefixed with "/media", so in this case the mount point becomes "/media/sda1". 3) Go to http://192.168.10.1/webcmd.shtml . 4) Type the following line in the "Command" input box: dd if=/dev/mtd4ro of=/media/sda1/firmware.bin 5) Click "Apply" 6) After few seconds, in the text area should appear this output: 30080+0 records in 30080+0 records out 7) Type "sync" in the "Command" input box and click "Apply". 8) At this point the OEM firmware is stored on the flash drive as "firmware.bin". The size of the file is 15040 KB. Installation: ------------ * Flashing instructions (OEM web interface): The OEM web interface accepts only files with names containing "WN531A6". It's also impossible to flash the *-sysupgrade.bin image, so we have to flash the *-initramfs-kernel.bin first and use the OpenWrt's upgrade interface to write the sysupgrade image. 1) Rename openwrt-ramips-mt7621-wavlink_wl-wn531a6-initramfs-kernel.bin to WN531A6.bin. 2) Connect your computer to the one of the LAN ports of the router with an Ethernet cable and open http://192.168.10.1 3) Browse to Setup -> Firmware Upgrade interface. 4) Upload the (renamed) OpenWrt image - WN531A6.bin. 5) Proceed with the firmware installation and give the device a few minutes to finish and reboot. 6) After reboot wait for the "WAVLINK" logo on the top cover to turn solid blue, and open http://192.168.1.1 7) Use the OpenWrt's "Flash Firmware" interface to write the OpenWrt sysupgrade image: openwrt-ramips-mt7621-wavlink_wl-wn531a6-squashfs-sysupgrade.bin * Flashing instructions (u-boot TFTP): 1) Configure a TFTP server on your computer and set its IP to 192.168.10.100 2) Rename the OpenWrt sysupgrade image to firmware.bin and place it in the root folder of the TFTP server. 3) Power off the device and connect an Ethernet cable from one of its LAN ports your computer. 4) Press the "Reset" button (and keep it pressed) 5) Power on the device. 6) After a few seconds, when the connected port LAN LED stops blinking fast, release the "Reset" button. 7) Flashing OpenWrt takes less than a minute, system will reboot automatically. 8) After reboot the WAVLINK logo on the top cover will indicate the current OpenWrt running status (wait until the logo tunrs solid blue). Revert to the OEM Firmware: -------------------------- * U-boot TFTP: Follow "Flashing instructions (u-boot TFTP)" and use the "firmware.bin" backup image. * OpenWrt "Flash Firmware" interface: Upload the "firmware.bin" backup image and select "Force update" before continuing. Notes: ----- * The MAC address shown on the label at the back of the device is assigned to the 2.4G WiFi adapter. MAC addresses assigned by the OEM firmware: 2.4G: *:XX (label): factory@0x0004 5G: *:XX + 1 : factory@0x8004 WAN: *:XX - 1 : factory@0xe006 LAN: *:XX - 2 : factory@0xe000 * The I2C bus and UART2 are fully functional. The headers are not populated.
