Those $50 devices are generally MIPS, with 32mb of ram and a single 100mb
port, if your lucky the switch chip might do vlans.

This month's VFAT image for the Beaglebone Black is badly broken. If you
want something workable use an older
image.Fedora-Minimal-VFAT-armhfp-20-1-sda.raw.xz

contains a kernel which keep oops'ing on certain operations, like an
outbound slogin attempt. I reported that and the response was kernel RPM
3.12.5-302 which results in a board which will not boot at all.

What do you mean by "this months image". The release image does have
some known and documented limitations but it's relatively stable for
the documented use case.


It looks like kernel-3.12.5-302 fixes various things for x86_64 machines, so
it is an improvement for them, yet it really wrecks an ARM installation. I
guess we can expect ARM to always be a secondary architecture, with anything
that benefits x86_64 users being pushed, regardless of its effects on other
users.

That's not exactly true. Firstly whether it be x86 or ARM no one
particularly device blocks a kernel release. If there's an issue with
a particular piece of HW it's then fixed in a later release. In the
case of the BB Black the 3.12.x kernel massively improves a number of
things such as usb, hdmi and other things. There was one known
regression which is the ethernet, which while it works isn't the most
stable. I've today pushed a patch that should fix this for the next
kernel build and I've put up a scratch kernel [1] for those that wish
to try it while we wait for the Fedora kernel devs to push a new
kernel.

We the Fedora ARM kernel people and wider testers are doing our best
with limited time and many devices to support with a greatly moving
target that is the upstream kernel. We do our best but there's many
combinations of hardware which people use in many different ways and
we do try our hardest to support all the many different ways and means
that people want to use Fedora on ARM.

Obviously Peter should have referenced 
http://pbrobinson.fedorapeople.org/arm-kernel/kernel-3.12.6-300.fc20.armv7hl.rpm, 
rather than the kernel-devel RPM. This RPM gives me a BeagleBone Black 
which has been working solidly with a fully updated Fedora 20 for the 
past few hours. Things are looking good.


Is Fedora 20 supposed to work on a Pandaboard? There are Pandaboard 
uboot files in the distro, but no reference to it on 
https://fedoraproject.org/wiki/Architectures/ARM/F20/Installation. I 
tried to install it, but I haven't been able to make it boot.

[fedora-arm] BeagleBone Black CPU speed

[Steve Underwood]

Hi,

It looks like the BeagleBone Black is still running at 550MHz with the 
latest Fedora 20. Does anyone know what is holding it back from running 
at 1GHz? Is the a uboot thing, or a kernel thing, or something else? I 
saw a version of uboot referred to as making the BBB run at 1GHz, but 
when I tried experimenting with that I got the same 550MHz clock speed.

Steve

As I reported earlier, using a Debian image runs (more than) 2x faster,
so it might be possible to analyze it, looking at what they did/use
(both Fedora and Debian are booted from SD, the stock eMMC is not changed).

with v3.12.x:
These 5 patches are needed:
https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.12/patches/cpufreq

or with v3.13-rcX:
https://github.com/RobertCNelson/linux-dev/blob/am33x-v3.13/patches/dts/0002-arm-dts-am335x-boneblack-add-cpu0-opp-points.patch

ps, while your at it, also add:
https://github.com/RobertCNelson/linux-dev/blob/am33x-v3.13/patches/dts/0001-arm-dts-am335x-boneblack-lcdc-add-panel-info.patch

to get the full kms experience over hdmi with the
CONFIG_DRM_TILCDC/CONFIG_DRM_I2C_NXP_TDA998X

Since they are both dts patches, you don't even have to rebuild the
kernel, just patch the dtb file..

Hi all,

Hey Robert do you have a rc ( 3.13 ) kernel rolled?.

Those $50 devices are generally MIPS, with 32mb of ram and a single
100mb port, if your lucky the switch chip might do vlans.


A quick look over the OpenWRT wiki shows this as only arm based option 
with 4 ports.


http://wiki.openwrt.org/toh/netgear/wnr854t

There are much more powerful MIPS systems such as the new C7 Archer 
based systems like this: http://wiki.openwrt.org/toh/tp-link/tl-wdr7500

I do..

https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.13

Just waiting for rc6 to fall, before i push it out to building farm..

The config is really minimal right now, going to throw the kitchen
sink at it tomorrow so v3.12.x users won't be missing stuff.

Interesting.  An ARMv5, though, so would need a Fedora remix for it and 
how current a ver at that?

But no Fedora on MIPS.

I know I can go with OpenWRT.  I would really not want to.  But if 
things don't start coming up my way, I may well have to.

It's very thin indeed on specs, only 32MB of ram etc

As a router OS OpenWRT is pretty good, much less fuss than a full distro 
of Linux and very light indeed.
