Hardware
--------
CPU: Mediatek MT7981
RAM: 512M DDR4
FLASH: 256M NAND
ETH: MaxLinear GPY211 (2.5GbE N Base-T)
WiFi: Mediatek MT7981 (2.4GHz 2T2R:2 5GHz 3T3R:2 802.11ax)
BTN: 1x Reset
LED: 1x Multi-Color
UART Console
------------
Available below the rubber cover next to the ethernet port.
Settings: 115200 8N1
Layout:
<12V> <LAN> GND-RX-TX-VCC
Logic-Level is 3V3. Don't connect VCC to your UART adapter!
Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.
As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.
In case this is not the case, OpenWrt will boot only one time, returning
to the ZyXEL firmware the second boot.
If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.
Installation TFTP / Recovery
----------------------------
This installation routine is especially useful in case of a bricked
device.
Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.
The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.
Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to nwa50axpro-openwrt-initramfs.bin.
$ atnf nwa50axpro-openwrt-initramfs.bin
$ atna 192.168.1.88
$ atns "192.168.1.66; tftpboot; setenv fdt_high 0xffffffffffffffff;
bootm"
Upon booting, set the booted image to the correct slot:
$ zyxel-bootconfig /dev/mtd9 get-status
$ zyxel-bootconfig /dev/mtd9 set-image-status 0 valid
$ zyxel-bootconfig /dev/mtd9 set-active-image 0
Copy the OpenWrt sysupgrade image to the device using scp.
Write the sysupgrade image to NAND using sysupgrade.
$ sysupgrade -n image.bin

Installation Web-UI
-------------------
Upload the Factory image using the devices Web-Interface.
As the device uses a dual-image partition layout, OpenWrt can only
installed on Slot A. This requires the current active image prior
flashing the device to be on Slot B.
If the currently installed image is started from Slot A, the device will
flash OpenWrt to Slot B. OpenWrt will panic upon first boot in this case
and the device will return to the ZyXEL firmware upon next boot.
If this happens, first install a ZyXEL firmware upgrade of any version
and install OpenWrt after that.
Installation TFTP
-----------------
This installation routine is especially useful in case
* unknown device password (NWA55AXE lacks reset button)
* bricked device
Attach to the UART console header of the device. Interrupt the boot
procedure by pressing Enter.
The bootloader has a reduced command-set available from CLI, but more
commands can be executed by abusing the atns command.
Boot a OpenWrt initramfs image available on a TFTP server at
192.168.1.66. Rename the image to owrt.bin
$ atnf owrt.bin
$ atna 192.168.1.88
$ atns "192.168.1.66; tftpboot; bootm"
Upon booting, set the booted image to the correct slot:
$ zyxel-bootconfig /dev/mtd10 get-status
$ zyxel-bootconfig /dev/mtd10 set-image-status 0 valid
$ zyxel-bootconfig /dev/mtd10 set-active-image 0
Copy the OpenWrt ramboot-factory image to the device using scp.
Write the factory image to NAND and reboot the device.
$ mtd write ramboot-factory.bin firmware
$ reboot
