Bluetooth on Udoo Neo ?
by Ken Harris
Is it possible to enable Bluetooth on Udoo Neo ? FYI, it uses the TI
WL1831 module.
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.

Kernel 5.0 value add for Fedora arm?
by Robert Moskowitz
I am looking at summaries of features in the 5.0 kernel.
I will have to dig into what the Fscrypt algorithm is and what that
means, but..
I see support for RPi touchscreen.
Will this add RPi touchscreen support for Fedora-arm? I suspect a lot
more is needed than just a driver.
What about other touchscreen for other arm SOC?
Anything else I should look at and maybe take advantage of....
thanks. Good weekend to all.

Problem with uboot 2019.04-rc2 and Cubieboad2
by Robert Moskowitz
The environment is only the uboot on the uSD and all partitions on the
sata HD.
I have been doing this for years now with no problem. uboot has always
switched to looking for the sata hd for partitions if no partitions on
the uSD:

Yes, this particular event is with the current Centos arm image, but
that should not matter. I have to get this Centos image built and
installed before I can test with Fedora arm image....
I grabbed a more recent uboot via:

When I try booting with the uboot in that image I get:

If there is a rc3 available, please tell me what image to grab for it

Meanwhile, it seems there is a problem here.

grub2-mkconfig: command not found
by Jeffrey Walton
Hi Everyone,
I deleted several old kernels today. grub.cfg listed an old kernel. I
attempted to regenerate grub.cfg but experienced:
grub2-mkconfig: command not found
What tool do we use to generate the grub menu?
Thanks in advance.

Problem with kernel-5.0.3-200.fc29.armv7hl on Raspberry PI 3B/3B+
by William Jacobs
Yesterday I installed the above referenced kernel on two Raspberry PIs, a 3B+ and a 3B. I also installed it on a BeagleBone Black and a Hummingboard2 (nxp i.mx6 Quad CPU).
On the BeagleBone Black and the Hummingboard, no problems at all, so this appears to be specific to the Raspberry PI platform or CPU. The Raspberry PI's are both actually running, but I noticed that top tells me that the load average is 4.0. But these things are not actually doing anything. Top does not show any process using more than 0.7% CPU and that it tells me that each core is nearly 100% idle. dmesg is not giving me any significant errors.
I have worked at finding the problem for a few hours and have not found a lot. But here is what I have found:
If I reboot to kernel 4.20.16, the problem goes away.
When booted into kernel 5.0.3 dmesg gives this line:
[ 16.342693] systemd[1]: Mounting Kernel Debug File System...
but I see nothing that indicated why this might be happening.
Anyone else try kernel 5.0.3 on a Raspberry Pi? Any thoughts on where to look for the problem?
Thanks very much!
Will

testing Fedora-Minimal-armhfp-30-20190326.n.0-sda on Cubieboard2
by Robert Moskowitz
I am at IETF104, and only brought a Cubieboard2 and forgot my sata drive
and sata adapter. Thus all testing is uSD and USB only until next Monday.
I installed minimal on a 4GB uSD and deleted all partitions, leaving
only the uboot.
I installed minimal on a 16GB uSD and expanded the rootfs to the full
size of the card.
First test was uboot only in the uSD slot and the full image USB
connected (uSD USB adapter).
The boot failed. We are still on the rc2 broken uboot:

The uboot DID recognize the USB device, but did not boot it.
The second test was to put the full image in the uSD slot. This booted
up properly, went through the console first boot dialog and then I could
log in as root.
Next test used the F29 uboot on the 4Gb uSD in the uSD slot and the full
image on the USB adapter:

So this uboot seems better, but it is not recognizing the USB drive.
Is there a later uboot than that in F29
(Fedora-Minimal-armhfp-29-1.2-sda) for me to test with?
Otherwise I don't see any other testing I can do until I get back Monday.
