Discussion:
[fedora-arm] Cubietruck wifi

Interesting observation.

With the latest uboot (2018.09) and Fedora 29-beta-Xfce

No wifi.  Nothing shows when I do 'ip a'

BUT...

Same uboot, but the Centos7 image:

CentOS-Userland-7-armv7hl-generic-GNOME-1804-sda

There is the wifi interface.  The Gnome install asks me if I want to
connect to any of the visible SSIDs.

How did the Centos arm team get this to work and not Fedora?  :)

Really not so important RIGHT now, as my CT is for a Centos server. I am
only planning on running Fedora on Cubieboard2 which do not have their
own embedded wifi.

Just a data point for now.

Another datapoint:

Centos is running the WPA Supplicant daemon.  Fedora is not.  But is
there a WPA Supplicant daemon in Fedora, or is this function merged into
NetworkManager?

Did you take a look at dmesg?, perhaps you can dmesg > boot.out and attach
it.

System is powered down, probably for the night.  I finished up what I
was going to do with it.  Tomorrow.  And do you mean the Centos on CT or
Fedora on CT image?

I think from both would be helpful, also would be a good idea to look at
the boot args from both and as much info you can get out of uboot on both.

( I know im not asking for much : ) ) ..

I am interested to see what the difference is.

Fedora runs it, in some cases, but it's started by NM on demand when
it needs it, there's also a iwd that replaces it in some situations.

own embedded wifi.
Just a data point for now.
We don't ship it because 1) it's not upstream in the Linux kernel or
linux-firmware 2) the information currently can't be redistributed
legally, for a couple of reasons. This is the same issue on the
Raspberry Pi and a number of other devices with broadcom chips. The
file that CentOS has now doubt chosen to ship is device specific but
linux currently deals with it generically so if another device has the
same wifi model with things like clocks/crystals and other settings
that are device or regional specific. This could cause random things
like actual wifi that shows up but doesn't work, it could actually
break the user's device or get the user in trouble for using
power/frequencies that are out of range. So the general stance of
Fedora is not do things like that and I'd much sooner a user not
having working wifi than cooking their device or getting them in
trouble with authorities.

All of the above being said I am working with a number of individuals
both within Red Hat and other organisations (this has literally taken
3+ years) to get this problem resolved and we're nearing the end game.
I don't have a specific timeframe but "Real Soon Now" is what I'm
hoping, the Raspberry Pi will be fist in the list to be resolved and
the rest should follow on not far behind, people's time pending.

Peter,

I am always very appreciative of what you and others there do for us. 
Given this information, I will not dig more into it.  I am looking into
the Nethserver community's Centos-arm work, so what Centos is doing on
my Cubietruck is of immediate value.  Maybe.  :)

I can wait for your Fedora-arm wifi general solution.

thanks

This will land into Fedora first but the solution is a generic
upstream so will benefit the entire linux ecosystem not just Fedora.
