If the board comes up with OpenWrt that means that the bootloader is
recent enough and knows about the new device tree overlays.
Using /etc/board.d/ is not enough in this case because it doesn't
overwrite existing configuration which may exist (and is fine to exist)
if the user updated with 'sysupgrade -F *.itb' and has kept
configuration. They would still need to manually set compat_version
even though the fact that the bootloader env has been updated can be
implied by the fact that the system has started.
Hence we can always set compat_version=1.1 for those two boards using
uci-defaults.

This allows loading modules with large memory requirements, recently needed
while testing on armvirt/32. Past forum discussions [1] and bug reports [2]
also raised this and the ipq806x target already set it in response [3].
Given this increases kernel image size by only ~1KB, is generally useful on
multi-platform kernels, and enabled by default on upstream arm32 Linux, add
it to the generic config.
The setting has similar utility on arm64, is a requirement for KASLR, and
already enabled on most OpenWrt aarch64 targets, so pull this into the
top-level generic config.

The router boots BL2 which than loads FIP (u-boot).
U-boot has hardcoded a command to always launch Zloader "mtd read zloader 0x46000000" and than "bootm". Bootargs are deactivated.
Zloader is the zyxel booloader which allow to dual-boot ubi or ubi2, by default access to zloader is blocked.
Too zloader checks that the firmware contains a particolar file called zyfwinfo.

Installation
------------
Keep in mind that openwrt can only run on the UBI partition, the openwrt firmware is not able to understand the zloader bootargs.
The procedure allows restoring the UBI partition with the Zyxel firmware and retains all the OEM functionalities.
1. Unlock Zloader (this will allow to swap manually between partitions UBI and UBI2):
- Attach a usb-ttl adapter to your computer and boot the router.
- While the router is booting at some point you will read the following: `Please press Enter to activate this console.`
- As soon as you read that press enter, type root and than press enter again (just do it, don't care about the logs scrolling).
- Most likely the router is still printing the boot log, leave it boot until it stops.
- If everything went ok you should have full root access "root@EX5601-T0:/#".
- Type the following command and press enter: "fw_setenv EngDebugFlag 0x1".
- Reboot the router.
- As soon as you read `Hit any key to stop autoboot:` press Enter.
- If everything went ok you should have the following prompt: "ZHAL>".
- You have successfully unlocked zloader access, this procedure must be done only once.
2. Check the current active partition:
- Boot the router and repeat the steps above to gain root access.
- Type the following command to check the current active image: "cat /proc/cmdline".
- If `rootubi=ubi` it means that the active partition is `mtd6`
- If `rootubi=ubi2` it means that the active partition is `mtd7`
- As mentioned earlier we need to flash openwrt into ubi/mtd6 and never overwrite ubi2/mtd7 to be able to fully roll-back.
- To activate and boot from mtd7 (ubi2) enter into ZHAL> command prompt and type the following commands:
atbt 1 # unlock write
atsw # swap boot partition
atsr # reboot the router
- After rebooting check again with "cat /proc/cmdline" that you are correctly booting from mtd7/ubi2
- If yes proceed with the installation guide. If not probably you don't have a firmware into ubi2 or you did something wrong.
3. Flashing:
- Download the sysupgrade file for the router from openwrt, than we need to add the zyfwinfo file into the sysupgrade tar.
Zloader only checks for the magic (which is a fixed value 'EXYZ') and the crc of the file itself (256bytes).
I created a script to create a valid zyfwinfo file but you can use anything that does exactly the same:
https://raw.githubusercontent.com/pameruoso/OpenWRT-Zyxel-EX5601-T0/main/gen_zyfwinfo.sh
- Add the zyfwinfo file into the sysupgrade tar.
- Enter via telnet or ssh into the router with admin credentials
- Enter the following commands to disable the firmware and model checks
"zycli fwidcheck off" and "zycli modelcheck off"
- Open the router web interface and in the update firmware page select the "restore default settings option"
- Select the sysupgrade file and click on upload.
- The router will flash and reboot itself into openwrt from UBI
4. Restoring and going back to Zyxel firmware.
- Use the ZHAL> command line to manually swap the boot parition to UBI2 with the following:
atbt 1 # unlock write
atsw # swap boot partition
atsr # reboot the router
- You will boot again the Zyxel firmware you have into UBI2 and you can flash the zyxel firmware to overwrite the UBI partition and openwrt.
Working features
----------------
3 gbit lan ports
Wifi
Zyxel partitioning for coexistance with Zloader and dual boot.
WAN SFP port (only after exporting pins 57 and 10. gpiobase411)
leds
reset button
serial interface
usb port
lan ethernet 2.5 gbit port (autosense)
wan ethernet 2.5 gbit port (autosense)
Not working
----------------
voip (missing drivers or proper zyxel platform software)
Swapping the wan ethernet/sfp xor port
----------------
The way to swap the wan port between sfp and ethernet is the following:
export the pins 57 and 10.
Pin 57 is used to probe if an sfp is present.
If pin 57 value is 0 it means that an sfp is present into the cage (cat /sys/class/gpio/gpio468/value).
If pin 57 value is 1 it means that no sfp is inserted into the cage.
In conclusion by default both 57 an 10 pins are by default 1, which means that the active port is the ethernet one.
After inserting an SFP pin 57 will become 0 and you have to manually change the value of pin 10 to 0 too.
This is totally scriptable of course.
Leds description
------------
All the leds are working out of the box but the leds managed by the 2 maxlinear phy (phy 5 lan, phy6 wan).
To activate the phy5 led (rj45 ethernet port led on the back of the router) you have to use mdio-tools.
To activate the phy6 led (led on the front of the router for 2.5gbit link) you have to use mdio-tools.
Example:
Set lan5 led to fast blink on 2500/1000, slow blink on 10/100:
mdio mdio-bus mmd 5:30 raw 0x0001 0x33FC
Set wan 2.5gbit led to constant on when wan is 2.5gbit:
mdio mdio-bus mmd 6:30 raw 0x0001 0x0080

Kernel setting CONFIG_IO_URING supports high-performance I/O for file
access and servers, generally for more performant platforms, and adds
~45 KB to kernel sizes. The need for this on less "beefy" devices is
questionable, as is the size cost considering many platforms have kernel
size limits which require tricky repartitioning if outgrown. The size
cost is also large relative to the ~180 KB bump expected between major
OpenWRT kernel releases.
No OpenWrt packages have hard dependencies on this; samba4 and mariadb
can take advantage if available (+KERNEL_IO_URING:liburing) but
otherwise build and work fine.
Since CONFIG_IO_URING is already managed via the KERNEL_IO_URING setting
in Config-kernel.in (default Y), remove it from those target configs
which unconditionally enable it, and update the defaults to enable it
conditionally only on more powerful 64-bit x86 and arm devices. It may
still be manually enabled as needed for high-performance custom builds.

Since CONFIG_DYNAMIC_DEBUG is already managed via the KERNEL_DYNAMIC_DEBUG

ipq40xx, ipq806x, filogic, mt7622, qoriq, and sunxi.

This deactivates the CONFIG_COMPAT kernel option.
With CONFIG_COMPAT the kernel will provide syscall interfaces for arm32
binaries in addition to the interfaces needed for arm64 binaries.
In OpenWrt the complete userspace is compiled for this specific
architecture and support for 32 bit ARM applications is not needed.
