Looks like we are close. But the error codes are persistent. I can not
copy/paste but serial does not load. Whatever I place in the first line of
the python file.
I tried: #!/bin/env/python and other shebangs (I learn!) but the error
remains exactly the same. Btw: I use python2.x
Any clue what to
Hi, I need your help,
I need to read data of an SPI Master device on the BeagleBone. Since the
SPI kernel driver doesn't support an SPI slave mode I have to implement it
in the PRU (Because the maximum frequency one BeagleBone's GPIO can be
toggle is only 15 KHz).

I've forgotten to mention. I am sending the clocks from the PRU 1 to PRU 0
at this time. So I know exactly how many clocks there is and the frequency.
The objective is to plug the sensor which I want to read the data after
having this working .

Try writing in assembly, or at least providing a listing of the PRU
code your compiler is generating. The C code you've written could
turn into very ugly assembly with a lot of memory reads (which are
*VERY* expensive on the PRU) depending on the compiler.
In general, for speed you only want the

Thanks a lot Robert Nelson for your quick responses and really

I am trying to automate feature "to verify the image flashing/contents

Hi everyone,
I'm trying to add at least three additional GPIO chip selects in addition
to the existing hardware CS for SPI0. I found a tutorial
here:

However, I'm trying to get this to work with the latest U-boot
Hello,
I have updated my machine to the newest image and kernel that
BBB.io/latest-images provide. Also, I use config-pin now. For example:
sudo config-pin P9.17 i2c and then try sudo config-pin P9.18 i2c, too. That
should open up your i2c address on your BBB or other bbb.io related boards.
Hello,
If you are using an environment, env, to run your software on boot, I may
be out of line. I do not use environments for my Linux Distros when running
software on boot. Um, I think if you just type up your software w/ Python2
and add the top line #!/usr/bin/python to the software, you
Okay and Hello Once More,
Seth here. I think (know) Jim F was on to something w/ your software and
setting up .service files for running on boot.
For example: Here is another test example to try out to learn more about
.service files and starting files on boot on the BBB (or other related
Hello,
I am still pursuing the LoadCape functionality if you are interested.
Please let me know if you are using this Cape.

Hello,
Use
this:
https://debian.beagleboard.org/images/bone-debian-9.5-iot-armhf-2018-10-07-4gb.img.xz
which can be found at bbb.io/latest-images. You can then use config-pin to
set up your "pinmuxing."
Seth
P.S. Use this cmd for P9.13 to use GPIO functionality: sudo config-pin

Dear Beagleboard,
I am using bmaptool image for flashing the images onto eMMC on Beagleboard
Could you please let me know how to verify whether the image is
successfully flashed onto eMMC or not , can we use bmaptool to verify the
image that is successfully flashed?
If bmaptool can be used,

Hi Seth,
I'm glad to hear from you. I am already using the latest-images iot build.
But I'm trying to learn how to reconfigure the 1-wire interface which has a
dts file configured to use P9.22 on the beaglebone black, and move it to a
different GPIO pin on the beaglebone blue. P9.13 (which I
I actually think what you need to do is something along the following line.
I don't think the shebang line makes a difference (rather, I know this) if
you pass the python script directly to the python binary.
ExecStart=/usr/bin/python2.7 /path/to/my_file.py
You should post your errors if Seth's
