Is it possible to enable Bluetooth on Udoo Neo ? FYI, it uses the TI
I tried :
hciattach -n ttymxc2 texas
... but got "Initialization timed out."
I also tried various combinations of bit rates and flow control.
Any tips are welcome.
Has anyone had any luck getting Fedora 28 to work on the Odroid C2?
I've tried downloading the Fedora 28 Server aarch.raw.xz image which i
put onto my sd card. I then moved the Archlinux aarch64 boot parition
into boot along with the lib/modules and lib/firmware folders from
Archlinux. This has been to no avail. I'm working on building the
hardkernel kernel myself now but have never actually compiled a kernel
myself so I'm not sure what I fully need to get the Fedora rootfs to
boot with the kernel.
If anyone has some guidance or a nice writeup on getting a bootable
kernel recognized by Fedora on the Odroid C2 that would be greatly
DOn't know if this is a general F29 problem...

I have other things to do today. Hopefully this well get fixed. Or
should I go ahead and update what will update?
With the latest uboot (2018.09) and Fedora 29-beta-Xfce
No wifi. Nothing shows when I do 'ip a'
Same uboot, but the Centos7 image:
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.
I see a few months ago in the mailing list that support was brought up (in
the context of F27) and it was mentioned that improving support for
Rockchips devices in general was intended for F28.
It doesn't appear that fedora-arm-installer currently supports the Rock64
board as far as I can tell.
I'm trying to figure out how to add support by adding to
/usr/share/arm-image-installer/boards.d and socs.d, as well as solving the
lack of appropriate uboot in /usr/share/uboot for Rock64.
I flashed (and tested successfully) a community built Debian Stretch image
and by comparing it's partition layout and some information from OpenSUSE I
can guess at what some of it should be, but I'm not entirely sure how to
make the appropriate files in socs.d, boards.d, and what all is needed in
Debian Stretch image that boots :
U-boot used in the above build :
OpenSUSE info : https://en.opensuse.org/HCL:Rock64

loader1 (partition 1) is the SPL, loader2 (partition 4) is the U-Boot. atf
(partition 5) per OpenSUSE is apparently some kind of "trust" image.
The reserved partitions (partitions 2 and 3) seem to just be all nulls.
The boot partition (partition 6) has extlinux/extlinux.conf apparently as
well as 'System Volume Information' (guessing that the origin of that
partition was built on Windows), and partition 7 is of course regular old
I'm not sure how fedora-arm-installer decides to partition things, it
wasn't obvious from socs.d/boards.d, so I'm not sure how to ensure that
when creating the soc/board scripts that the correct layout is maintained.
From glancing at the source code for fedora-arm-installer it seems like it
just extracts the image onto the media and assumes the layout based on what
was in the image, which might present a problem if the unified AArch64
image has only 3 partitions? Unless it would be expected that Fedora would
have it's own build of uboot that would ensure things didn't need all those
other partitions ?
Anyways, I'm happy to either figure this out on my own if you can point me
in the right direction or if you already have some WIP that needs a
volunteer to test it, to do be your guinea pig.

Sure, all of the above isn't solvable now, we need to look at F-29+
Now is the time to ensure everything that is needed here for F-29 to
be there and all testing should be done there.

Use Fedora 29.
