Running kernel 4.4 and trying to read a DS3234 clock on the second SPI
port I can suppress the HDMI pins in uEnv.txt with:
dtb=am335x-boneblack-emmc-overlay.dtb
optargs=cape_disable=bone_capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN
(uEnv.txt isn't loading the "universal overlay".)

Does anyone know the set of git commands needed to update one of R Nelson's

Yes, but the cpufreq directories under /sys just aren't there. It has to

Okay, I'm officially confused. I've been trying to increase the speed
of my BBB from the default 550MHz to 1GHz, and failing; this is with the
elderly 3.8.13-37 sources. After a few failures I went back to a seriously
ancient kernel, just to get something to run, and found that the

Sorry, I should have said that I'd tried cpuinfo. I can change the
governor (with -g), but not the frequency:
tuppence ~ # cpufreq-set -f 1000MHz
tuppence ~ # cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpuf...@vger.kernel.org, please.

I've been looking at the speed of my BBB and not really understanding
what's going on. The files under /sys/devices/system/cpu/cpu0/cpufreq
show that the performance governor is in use, but the speed is a constant
550,000 whatever the load. The "scaling_setspeed " entry
probably reflects this; do
I thought one of the advantages of the device tree setup was that it was
independent of the kernel,
but apparently a fair amount of porting work is still needed between kernel
versions. Does anyone
know how roughly how much of a DT can be kept, from kernel to kernel?

When I first got a BBB around the middle of 2013 it took me a week to sort
out a working device tree compiler; that's now a straight download from
Robert Nelson's site; and there are a lot of other improvements. However,
the BBB software isn't really stable enough for the long-term, albeit

I need to build a patched BBB kernel, so have unwillingly started one of
my usual vicious fights with git. The first question to answer is where
the current BBB linux kernel sources are kept - I don't think github is
the default, though some sources can be found there. It seems to be a
choice bet

one.)
Does anyone know the most recent version number of Robert Nelson's 3.8
kernel for the BeaglBone Black?
After updating I have 3.8.13-bone22.3, but I thought there was something
more recent.
