Specifications: - SoC: ar9341 - RAM: 32M - Flash: 4M - Ethernet: 5x FE ports - WiFi: ar9341-wmac Flash instruction: Upload generated factory firmware on vendor's web interface. This changes the key assignment compared to ar71xx support of this device, since of the two keys on the device one is used as combined Reset/WPS and the second one as WiFi on/off button. Despite, the reset button required GPIO_ACTIVE_HIGH to work correctly.
