Hello,

I tried config-pin example from Exploring BeagleBone, 2nd Ed.:

debian@beaglebone:~$ config-pin -l p2.08
ERROR: open() for /sys/firmware/devicetree/base/ocp/P2_08_pinmux/pinctrl-names failed, No such file or directory
debian@beaglebone:~$

Any comments ?

Thanks.

P2_08 is a PocketBeagle reference, I thought you had a normal BBB?

Oh yes, I didn't notice that example is for PocketBeagle.
So, for BBB it should be something like this: config-pin -l p9.08 or config-pin -l p8.08?
Regards.

Just tried p8 and p9:

P9.08 is a SYS_5V, definitely not user touchable...

debian@bbb-pwr02-ser10:~$ config-pin -l P8.08

Available modes for P8_08 are: default gpio gpio_pu gpio_pd gpio_input timer

Please run:

sudo /opt/scripts/tools/version.sh

and we can help point out what's wrong..

Your booting the mainline kernel default device tree, thus config-pin
will not work.

Either use factory 2020-04-06 image or feel free to grab a newer snapshot:

I've also tried on the image that I built using create-sdcard.sh script from TI SDK (when booted from SD card):

root@am335x-evm:~# config-pin -l P8.08

root@am335x-evm:~#


Here is link where the procedure is described: Linux SD Card Creation Guide
By the way this Linux image is quite strange as some standard Linux commands aren't recognized, e.g. apt package manager.

I've found only one image that matches closely BBB ... at least it follows from its name:
from:

In other "stretch" folders from this repository I didn't find images that start with BBB or am335.
So, the only available image for BBB is BBB-blank-debian-10.5-console-armhf-2020-09-07-1gb.img.xz ?

config-pin is a beagleboard.org script...

They use yocto, apt isn't installed by default..

Frankly speaking I didn't find any descriptions except name of kernel.
There are 5 images in "stretch" family:
  • Console
  • IoT
  • IoT TIDL
  • LXQt
  • LXQt TIDL
I suppose that Console stands for image without graphical environment ?
All others are perhaps with graphical environment. Correct ?
Then IoT stands for image with support of some network protocols, e.g MQTT ?
LXQt probably stands for image wit Qt preinstalled ?
But what signifies TIDL ?

Sincerely,

Pavel.

Console = smallest, very little installed
IoT = bigger than console with out of box BeagleBoard.org stuff
(Cloud9, Node-Red, etc..).
LXQt = IoT + LXQt

TIDL = TI https://training.ti.com/texas-instruments-deep-learning-tidl-overview

Ok

IoT = bigger than console with out of box BeagleBoard.org stuff
(Cloud9, Node-Red, etc..).
Does exist somewhere the whole list of features ?

LXQt = IoT + LXQt
Frankly speaking, didn't understand.
In the preview they are talking on AM57x. So, does not work for BBB?
Sincerely,
Pavel
P.S. Is my supposition correct that all images except console feature graphical environment ?

It's just the default out of box experience, so things really get
added all the time, whether from GSOC or any other code events.

LXQt is a lightweight desktop based on Qt

TIDL is AM57xx only, it takes a ton of room, so those libraries are
not installed on a base image.

Only the LXQt images have xorg installed.

After flashing bone-eMMC-flasher-debian-10.5-iot-armhf-2020-08-25-4gb.img the tool config-pin works.
Thanks !
Before I had this image in eMMC:
bone-debian-10.3-iot-armhf-2020-04-06-4gb.img

Why on BBB-dedicated page they put "mainline kernel default device tree" image ?

Sincerely.

Pavel.

Moreover, the -q option (pin querry) doesn't provide information of the pin mode (direction) and its value:

debian@beaglebone:~$ config-pin -q P9.12

Current mode for P9_12 is:     gpio

debian@beaglebone:~$


In fact, there is no information at all!

The older config-pin is, as I recall, a shell script. The current
config-pin is a compiled executable.

debian@beaglebone:~$ which config-pin

config-pin [-a] <pin> <mode>
Set <pin> to <mode>, configuring pin multiplexing and optionally
configuring the gpio. Valid <mode> strings vary based on <pin>,
however all pins have a default and gpio mode. The default mode is
the reset state of the pin, with the pin mux set to gpio, the pull
up/down resistor set to it's reset value, and the pin receive buffer
enabled. To setup gpio, the following <mode> strings are all valid:

gpio :
Set pinmux to gpio, existing direction and value unchanged
in | input:
Set pinmux to gpio and set gpio direction to input
out | output :
Set pinmux to gpio and set gpio direction to output
hi | high | 1 :
Set pinmux to gpio and set gpio direction to output driving
high
lo | low | 0 :
Set pinmux to gpio and set gpio direction to output driving low

To enable pull-up or pull-down resistors, a suffex may be appended to
any of the above gpio modes. Use + or _pu to enable the pull-up
resistor
and - or _pd to enable the pull-down resistor. Examples:

in+ | in_pu:
Enable pull-up resistor and setup pin as per input, above.
hi- | hi_pd:
Enable pull-down resistor and setup pin as per high, above.
While the pull-down resistor will be enabled, it will not do
much
until application software changes the pin direction to input.

ANYTIME you are following a book and encounter a difference, you need
to study which version of the OS was present at that time. Even the 2nd
Edition of the book was likely behind a version or two by the time it was
printed.

Per page 32 of the book, it was written when Debian Stretch was still
in use. Standard images have been Debian Buster since April of this year
(though the config-pin change might have occurred anytime in 2019, or even
late 2018, as the 2nd edition shipped [from Amazon] January 14 2019). Based
on some screen captures, the book was using a February 2018 image, and the
examples were run in April 2018. That's a whole 2.5 years ago.

{Side note: Raspberry-Pi went to Buster in the summer of 2019, about two
weeks before Debian Buster was officially released -- the R-Pi 4B was
different enough that all the work to get it to run was done on pre-release
Buster.}

Hi there!
I have the same problem, with my BeagleBone.
When I run the command:
root@beaglebone:~# /opt/source/bb.org-overlays/tools/beaglebone-universal-io/config-pin -q P2_06

I get this error msg:
P2_06 pinmux file not found!
bash: /sys/devices/platform/ocp/ocp*P2_06_pinmux/state: No such file or directory
Cannot write pinmux file: /sys/devices/platform/ocp/ocp*P2_06_pinmux/state

As I read, I only have to flash a new image which is bone-eMMC-flasher-debian-10.5-iot-armhf-2020-08-25-4gb.img as Pavel mentioned it?
Then it will work?

Thx
Regards,
Bence
