Hardware
--------
CPU: Qualcomm Atheros QCA9561
RAM: 64M DDR2
FLASH: 16M SPI-NOR
ETH: 1x WAN - 2x LAN
WiFi: QCA9561 3T3R
BTN: 1x Reset - 1x WPS
LED: 1x Blue - 1x Red - 1x Yellow
UART: TX - GND - RX - VCC (From ethernet port)
115200n8 - 3.3V
Installation
------------
1. Connect to the device via UART.
2. Interrupt the U-Boot on power-on by pressing enter when prompted.
3. Connect you computer to one of the routers LAN ports.
Assign yourself the IP 192.168.31.10/24.
Copy the OpenWRT initramfs image to a tftp server root directory.
Rename the image to 'x4q.bin'.
4. Load the initramfs image to the router by executing following command
in U-Boot. The image will boot afterwards.
> tftpboot 0x81000000 x4q.bin; bootm
5. SCP the sysupgrade-image into '/tmp'.
Remember to assign yourself an IP in 192.168.1.0/24 for this step!
6. Install OpenWRT permanently by executing
> sysupgrade -n /tmp/<OpenWRT-sysupgrade-image>
