I-O DATA WN-DX1167R is a 2.4/5 GHz band 11ac rotuer, based on MediaTek MT7621A. Specification: - SoC : MediaTek MT7621A - RAM : DDR3 128 MiB - Flash : NAND 128 MiB - WLAN : MediaTek MT7615D (2.4/5 GHz, 2T2R) - Ethernet : 5x 10/100/1000 Mbps - Switch : MediaTek MT7621A (MT7530) - LEDs/Input : 2x/3x (2x buttons, 1x slide-switch) - UART : through-hole on PCB - J5: Vcc, TX, RX, NC, GND - 57600 bps Flash instruction using initramfs image: 1. Boot WN-DX1167R normally 2. Access to "http://192.168.0.1/" and open firmware update page ("ファームウェア") 3. Select the OpenWrt initramfs image and click update ("更新") button to perform firmware update 4. On the initramfs image, perform sysupgrade with squashfs-sysupgrade image 5. Wait ~120 seconds to complete flashing Notes: - configuration in DeviceTree of DBDC (Dual-Band-Dual-Concurrent) mode for MT7615D chip is not supported in mt76 driver - last 0x80000 (512 KiB) in NAND flash is not used on stock firmware - stock firmware requires "customized uImage header" by MSTC (MitraStar Technology Corp.), but U-Boot doesn't - uImage magic (0x0 - 0x3) : 0x434F4D43 (COMC) - header crc32 (0x4 - 0x7) : with data length and data crc32 - image name (0x20 - 0x37) : model ID and firmware versions - data length (0x38 - 0x3b): kernel + rootfs - data crc32 (0x3c - 0x3f) : kernel + rootfs Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com> Reviewed-by: Sungbo Eo <mans0n@gorani.run>
