Zyxel NWA50AX
********************
Zyxel NWA50AX is quite close to the GL-MT300N-v2 "Mango" device, but it is based on the MT7621
chipset instead of the MT7628.
Installation
============
This device is pretty, but, due to its A/B capabilities, can be a bit hard
to use completely.
The stock vendor firmware is a downstream fork of U-Boot: <https://github.com/RaitoBezarius/uboot-nwa50ax>
with restricted boot commands. Fortunately, OpenWrt folks figured out trivial command injections,
so you can use most of the OpenWrt commands without trouble by just command injecting
atns, atna or atnf, e.g. atns "; $real_command".
From factory web UI, you can upload the result of the zyxel-nwa-fit output.
From another operating system, you need to `dumpimage -T flat_dt -p 0 $zyxel-nwa-fit -o firmware.bin`,
`flash_erase $(mtd partition of the target partition firmware or zy_firmware) 0 0`, then you complete by
`nandwrite -p $(mtd partition of the target partition firmware or zy_firmware) firmware.bin`.
How to put the firmware.bin on the machine is left to you as an exercise, e.g. SSH, TFTP, whatever.
From serial, you have two choices:
- Flash this system via U-Boot:
same reasoning as from an existing Linux system, two choices:
- ymodem the binary, perform the write manually, you can inspire yourself
from the `script` contained in the vendor firmware, those are just a FIT containing a script.
- prepare a FIT containing a script executing your commands, tftpboot this.
- boot from an existing Liminix system, e.g. TFTPBOOT image.
- boot from an OpenWrt system, i.e. follow OpenWrt steps.
Once you are in a Linux system, understand that this device has A/B boot.
OpenWrt provides you with `zyxel-bootconfig` to set/unset the image status and choice.
The kernel is booted with `bootImage=<number>` which tells you which slot are you on.
You should find yourself with 10ish MTD partitions, the most interesting ones are two:
- firmware: 40MB
- firmware_1: 40MB
In the current setup, they are split further into kernel (8MB) and ubi (32MB).
Once you are done with first installation, note that if you want to use the A/B feature,
you need to write a _secondary_ image on the slot B. There is no proper flashing code
that will set the being-updated slot to `new` and boot on it to verify if it's working.
This is a WIP.
Upgrading your system can be achieved via:
- `liminix-rebuild` for the userspace.
- `flash_erase` + `nandwrite` for the kernelspace to the other slot than the one you are booted on,
note that you can just nandwrite the mtd partition corresponding to the *kernel* and not the whole firmware.
If you soft-bricked your AP, i.e. you cannot boot anything in U-Boot, no worries, just plug the serial console,
prepare a TFTP server (via `tufted` for example), download vendor firmware, set up `atns`, `atnf`, etc. and run `atnz`.
This will reflash everything back to normal via TFTP.
If you hard-bricked your AP, i.e. U-Boot is telling you to transfer a valid bootloader via ymodem, just extract
a U-Boot from the vendor OS, send it via ymodem and use the previous operations to perform a full flash this time
of all partitions.
Note that if you erased your MRD partition, you lost your serial and MAC address. There's no way to recover the original one
except by reading the physical label on your device!
If you super-hard-bricked your AP, i.e. no output on serial console, congratulations, you reached one of the rare state
of this device. You need an external NAND flasher to repair it and write the first stage from Mediatek to continue the previous
recovery operations.
Development TODO list:
- Better support for upgrade automation w.r.t. to A/B, e.g. automagic scripts.
- Mount the logs partition, mount / as overlayfs of firmware ? rootfs and rootfs_data for extended data.
- Jitter-based entropy injection? Device can be slow to initialize its CRNG and hostapd will reject few clients at the start because of that.
- Defaults for hostapd based on MT7915 capabilities? See the example for one possible list.
- Remove primary/secondary hack and put it in preinit.
- Offer ways to reflash the *bootloader* itself to support direct boot via UBI and kernel upgrades via filesystem rewrite.

## Boot blessing via Zyxel
## =======================
## Boot blessing is the process to bless a particular boot configuration
## It is commonly encountered in devices with redundant partitions
## for automatic recovery of broken upgrades.
## This is also known as A/B schemas, where A represents the primary partition
## and B the secondary partition used for recovery.
## To use boot blessing on Liminix, you need to have the support of
## your bootloader to help you boot on the secondary partition in case of
## failure on the primary partition. The exact details are specifics to your device.
## See the Zyxel NWA50AX for an example.
## TODO: generalize this module.
