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.
