Hardware
--------
CPU: Qualcomm Atheros QCA9563
RAM: 128M DDR2
FLASH: 16MB SPI-NOR
WiFi: Qualcomm Atheros QCA9563 2x2:2 802.11n 2.4GHz
Qualcomm Atheros QCA9880 2x2:2 802.11ac 5GHz
Antennas
--------
The device features internal antennas as well as external antenna
connectors. By default, the internal antennas are used.
Two GPIOs are exported by name, which can be used to control the
antenna-path mux. Writing a logical 0 enables the external antenna
connectors.
Installation
------------
1. Download the OpenWrt sysupgrade image to the device. You can use scp
for this task. The default username and password are "ubnt" and the
device is reachable at 192.168.1.20.
$ scp -O openwrt-sysupgrade.bin ubnt@192.168.1.20:/tmp/firmware.bin
2. Connect to the device using SSH.
$ ssh ubnt@192.168.1.20
3. Disable the write-protect
$ echo "5edfacbf" > /proc/ubnthal/.uf
4. Verify kernel0 and kernel1 match mtd2 and mtd3
$ cat /proc/mtd
5. Write the sysupgrade image to kernel0 and kernel1
$ dd if=/tmp/firmware.bin of=/dev/mtdblock2
$ dd if=/tmp/firmware.bin of=/dev/mtdblock3
6. Write the bootselect flag to boot from kernel0
$ dd if=/dev/zero bs=1 count=1 of=/dev/mtd4
7. Reboot the device
$ reboot
