Can the OPI5 be Configured to Run LCNC?

Hi,
most probably you lose th RT patch, it happens also to me simply with APT UPGRADE.. but I patched again with deb files generated.
Now I have a image well done, latency OK, vnc working, all ok except wifi, this no way.. but for the rest it's ok.
I have a USB AC1200 and a Cisco USB and I tried to configure in menuconfig most of board present but some of them doesn't allow to build,
what I have enabled doesn't make the USB adapter working..
Now I have 2-3 days out, next week I will try again.
It's really enough to enable the driver in the menu config or there is a kind of service that should be enable as well?

@kanuboy13b Like Guglielmi said possibly you've upgraded the kernel. To prevent this from happening:
sudo apt-mark hold linux-image-legacy-rockchip-rk3588

The hoops with Armbian is because we're using an unsupported kernel, but you're free to build your rt arch system. I've tried arch a few times, it's not for me, too much hassle to make basic things work.

@Guglielmi Do you mean the RTL8812 like this one?

Enabling the driver should be enough, if you've got the one with the RTL8812 chip I've one here to test.

Exactly! It's that device, I bought on Amazon but I can say identical.
Sorry if I did not inserted enough detail in the previous post but I'm not at home so I can't take a picture..
I remember enabling something like RTL88x2eu it does't build, with other drivers less similar, it build but not work..

I do actually have the 8814EU there are different versions of these, you could check which one you've with lsusb.
To build different realtek drivers together you'll need to build them as modules, otherwise they will conflict each other.

Could you try this kernel with most usb wifi drivers enabled:

At least the RTL8814EU does work with this kernel.
If it still doesn't work you might need to install iw: sudo apt install iw

I will try as soon as I'm back at home.
I found the device I bought:
AC 1200

Identical.
before the patch it was working with armbian.
Maybe I could compare the config file in the drivers section to understand which one should be enabled..
I will work on it!

Hehe, yeah.... Arch is umm not for many people. I only was able to get as far as I did because it was heavily documented. Traversing unknown waters with that distro without completely knowing what your doing is severely ill advised, trying to do what we're doing would probably frustrate me only more than I already am.

I kinda figured that there were going to be issues getting a RT kernel working on the OPi5, I just figured it would be more drivers and config files, not missing dtb files that are essential for the device to boot. On the topic of unsupported kernel, has there been any interested from the Armbian group in making an official RT build of Armbian? Or is there just no demand for one hence all the hoop jumping.

So I should be able to fix the by reinstalling the Linux-image and Linux-headers deb files using apt install or dpkg  correct?
