If there is a better place for this post please move - after all, pinmux is
for more than GPIO, right?
I've been trying to figure out why pinmux-helper is needed. I've searched
and found initial RFC and followup in the early years (by Charles
Steinkuehler) and I understand the motivation (I thi
Hi, I am fairly new to Linux and don't know what all kinds of packages
exist out there.
I have a custom board based on a Beaglebone Black, but in addition to the
10/100 wired 'eth0', it also has wifi 'wlan0' (WL1835MOD) and a USB 4G
modem (Nimbelink) 'usb0'.
Is there a 'connection manager' pac
I think the primary use for the eQEP is to decode shaft encoders that are
being used to replace analog controls for volume control, tuning, tone
controls, etc.
In other words, knobs for applications suited for them, but you don't
digitize the analog knob output, you go directly into the digital

My desire is to get support for eQEP upstream in the mainline Linux
kernel. I don't believe it is easy to get new misc drivers merged. IIO
seems to be the only subsystem that is suitable but
I'm actually looking into using an ODRIOD XU4 for a build machine. I bought
one, and have had it here for a couple weeks now. I just have not had time
to work with it yet.
The XU4 is an octa-core SBC with quad A15's running at 2Ghz, and quad A7's
which I do not recall what frequency these core run
The 100pF cap, C204, seems to me to be almost useless without a series bead
(or resistor) to divide down the EMI signal (2.4GHz).
That said, if UART2 pin is re-purposed as SPI_CLK, then I agree that C204
could be problematic.

Take these as general answers, the people who build the images would have
to answer detailed questions, about exactly what is included in each type
of image.
The standard image has everything in it to drive a local display screen via
the HDMI or LCD connections, and multiple applicatio
Hi, William -
Thanks for the suggestions. I think I know Linux well enough to start
learning the nuances of how its embedded features work. And, I'm already
somewhat familiar with various peripheral devices. In another job, I wrote
drivers/interfaces for things like I2C, SPI, UART, memory, etc.

There are several possible paths. Since you mentioned Derek Molloy's book,
here is my project which was inspired by his chapter on the PRU:

If you look at this, you will see that I used the RemoteProc framework.

I'm trying to learn to program the PRU's on the BeagleBone Black to provide
a stable and accurate clock pulse in the 10kHz to 800kHz range and I'm
having a difficult time finding what is best to learn. I started with the
Exploring BeagleBone book by Derek Molloy which is fantastic but with the

I have no idea what groups they read, if any at all.

I attempted to find a minimal console image and found the IoT image on the
latest firmware images page[1]. Subsequently, I discovered a console image[2].
Please correct me if I am wrong, but I believe that the console image is even
more striped down the the IoT image.
