SoC: MediaTek MT7621AT RAM: 128M (Winbond W631GG6KB-15) FLASH: 16MB (Spansion S25FL128SA) WiFi: MediaTek MT7603EN bgn 2SS WiFi: MediaTek MT7612EN nac 2SS BTN: Reset - WPS LED: - Power - LAN {1-4} - WAN - WiFi 2.4 GHz - WiFi 5 GHz - USB UART: UART is present next to the Power LED. TX - RX - GND - 3V3 / 57600-8N1 3V3 is the nearest one to the Power LED. Installation ------------ Via TFTP: 1. Set your computers IP-Address to 192.168.1.75. 2. Power up the Router with the Reset button pressed. 3. Release the Reset button after 5 seconds. 4. Upload OpenWRT sysupgrade image via TFTP: > tftp -4 -v -m binary 192.168.1.1 -c put <IMAGE> Via SSH: Note: User/password for SSH is identical with the one used in the Web-interface. 1. Complete the initial setup wizard. 2. Activate SSH under "Administration" -> "System". 3. Transfer the OpenWrt sysupgrade image via scp: > scp owrt.bin admin@192.168.1.1:/tmp 4. Connect via SSH to the router. > ssh admin@192.168.1.1 5. Write the OpenWrt image to flash. > mtd-write -i /tmp/owrt.bin -d linux 6. Reboot the router > reboot Signed-off-by: David Bauer <mail@david-bauer.net> (cherry picked from commit 14e0e4f138e35c3e2a15cc3a836c939547ee053b)master
