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.
Additional details regarding Zloader can be found here:

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

Instead of referring to a redundant job and ENV variables, rework build
workflow to accept and require split target and subtarget and use them
directly from inputs.
Rework each user and pass a JSON of tuple to matrix include with each
target/subtarget combination to test. Special notice this doesn't use
the github actions matrix combination feature but reference each

Instead of allocating a 1024 byte buffer on the stack for the SHA1

That was a workaround for OpenWrt generation of config files. This patch
was used to postpone returning from probe function until loading

All of that is not needed anymore thanks to the ieee80211 hotplug.d
script introduced in the commit 5f8f8a3661 ("base-files, mac80211,

Currently, SSDK is rather special in the sense that its not being built as
a proper out of tree module at all but rather like a userspace application
and that involves a lot of make magic which unfortunately broke with make
version 4.4 and newer.
Luckily QCA finally added a way to build SSDK as an out of tree module
and it uses the kernel buildsystem which makes it compile with make 4.4
as well.
So lets backport the support for it and switch to using it.

(cherry picked from commit e2f9fa4204)
This makes the prereq stage update the symlinks
installed into staging_dir/host/bin
by rearrainging the way they are verified.
Before, seeing or installing a symlink would result in
a successful exit code, and not installing a symlink
would result is a failed exit code. However,
that is not able to account for the difference
between existing good and bad links, or whether
the link would be the same if it was reinstalled,
because the check can match the program to a different path.
Instead, let a success exit code represent
identifying an existing symlink as exactly the same
as what would be installed if it did not exist,
and let a fail exit code represent
needing to install the symlink
or not having a match to the check criteria.
The failing exit code is caught by a new second attempt
for all of the check-* targets which will then indicate
to the user that there was an update by having a success
exit code when the check is run again and the link is the same.
When there is nothing to update, the checks will run only once.
This relies on the ls command to be POSIX-conformant with long format:
"path/to/link -> target/of/link"
Also, make sure the symlink is executable, not just a file,
and the directory only needs to be created once.

The getrandom syscall is not hanging at bootup any more if there is
not enough entropy. This was fixed upstream in 2018 in commit:
a9cf659e05
This OpenWrt patch is not needed any more.
This reverts commit e64463ebde ("util-linux: avoid using the getrandom syscall")
