There are on Mikrotik site in download archive
Yeap, find in Stable release tree
Some more progress, got BDF-s extracted.
Without proper BDF-s WLAN was around 5 times worse.
Most of the things are working, I am now working on packaging and how to pernamently flash.
This uses a uncommon layout in which a UBI volumes for kernel and rootfs are used, but kernel is also kept in compressed UBIFS.
I tried without UBIFS and RouterBoot really does not like that.
Ok, so I did some digging and testing.
It appears that RouterBoot does not require kernel and rootfs to be separated with partitions but only UBI volumes.
It also does not care if the kernel is named "kernel" or "Kernel" like in ROS images.
All it cares about is that the kernel is packed in UBIFS, without UBIFS it won't boot the kernel at all, so I manually packed the kernel in UBIFS per what stock kernel is packed and ubinized it and that boots.
So, we just gotta find a way to pack the kernel in UBIFS in OpenWrt buildroot directly.

Big work, many thx, very interesting and waiting next news
OK, so a little update.
The weekend was mostly spent on figuring out how to permanently flash the image as there is no support for the method MikroTik uses on these NAND devices.
Unforunately, its still hit and miss.
You can check the RB450Gx4 thread for some details:
Ok, finally got the sysupgrade working so it can be flashed pernamently.
Now, its mostly complete, but still gotta figure out the WLAN and ETH generic LED-s as there is only one WLAN LED.
For those willing to do some testing my branch is here:

Good news, many tnx for your wokr. Wich wersion of RouterBoot we need to install 6.46.6?
Now I can't test the firmware, my PC has gone to a better world, in 5 days a new laptop with Ryzen 7 will arrive )
Potentially newer RouterBoots will also work, they just dont work for me.
Hey! Can you give me some basic instructions on how to build and test the firmware? I am completely new to this but I am eager to have openwrt instead of routerOS!
It is built like any other OpenWrt image, clone the tree, select the board and build.
OpenWrt has docs on that already.
For installation there are instructions in the commit message:
Please note that this is not finished and that you may be stuck in bootloop,
Ok thanks!! I will wait and keep monitoring this thread then
On debian,

git clone https://github.com/robimarko/openwrt.git
cd openvpn
git branch
Check which branch your on you need to switch to hap ac3
git checkout mikrotik/hap-ac3
You will notice
master
* mikrotik/hap-ac3
From there you can do the standard:
./scripts/feeds update -a
./scripts/feeds install -a
make menuconfig
Then select the target : IPQ40XX
subtarget: mikrotik
target profile: hap ac3
And so on that should get you going.. the more folks testing the better. ( make sure to backup your Lic file and if you can bootimage prior to upgrades to backtrack) unless you know what your doing

Shortening my original post,
The initramfs works fine,

Looks like the hard and soft config have hard coded versioning someone know how to change these files to accept lower versions perhaps uboot ofset uploads?`
There is a hardcoded factory version in the soft config.
You can search for it with a hex editor and change it then flash the soft_config to the partition.
Then you will be able to downgrade below, but if DHCP is working there is no need to downgrade
I have been really busy and have not been able to debug the pernament sysupgrade as its still hit and miss with sucess.
So I have already hex edited both bin files by dumping them with dd, the trouble is I can dump but how do I write them back, mtd has no permissions, also cannot erase the partitions and rewrite to them or mount them from alternate locations, I have no dhcp , the issue boils down to the factory firmware not being downgraded thats all it is atm
You can use kmod-rw to enable RW and then use dd to flash, but note that DD does not erase things before writing like mtd does.
Its not being downgraded as you are trying to downgrade below the one it shipped with, that can be done but only by editing the soft config
ahh I think this is what I was missing I was trying to install kmod-mtd-rw but no support for arm alright will give this a go
You need to include it in the image, opkg cant install it after.
Alright I will work on recompiling this the thx, this is making a lot more sense nowm should then be able to downgrade and do the sysupgrade.
