Happy to help; I have worked some with these examples, so feel free to reach
out if you have any questions!

Hi All,
I am trying to implement deterministic data acquisition on the Beaglebone
AI.
I was thinking of using the PRU with the ADC as it is done on one the
TechLab example analogIn.pru0.c
Ok, will do!
That was also my felling... do you know why they keep breaking it ? That's
quite annoying

Hi,
I had the same problem last year so I created this small documentation:
https://github.com/PierrickRauby/PRU-RPMsg-Setup-BeagleBoneBlack
It should work, if not, do not hesitate to tell me!

Hi Filippo
How are you trying to toggles the PRUs? I do not have a BBB with me this
weekend but I’ll have a look at it on Monday.
BTW, I have struggled with PRU too so I’ve wrote this memo:

help you
Thanks
Hi John,
Thanks for the answer, I did use u-boot overlays and setup the uEnv.txt to
load the right overlay. BTW, I am rebooting the BeagleBone every-time I
want to load a new overlay, can you confirm that it's the only way to do it
?
I'll try to use the IIO Oscilloscope, however as I have
Hi all,
First I am using a beaglebone black wireless Linux debian 4.9.45-ti-r57. I
am trying to use a thermocouple bridge max31855 and a K-type thermocouple,
my user space application is running Bonescript. Unfortunately the bridge
communicate through SPI which does not seem to be supported by
Hi all,
I am working with the Beaglebone Black Wireless Linux debian 4.9.45-ti-r57
in my university. I would like to connect it to my university's

computer to the wifi).
I look to several post and I successfully
Yes, sorry, my mistake I was looking to section 12.3.3 in the TRM instead
on looking to the STEPCONFIG register description sections.

Hi John,
Thanks a lot for this very complete answer ! I think I understand it now,
the last point I am not sure about is:
ti,chan-step-avg = <1 1 1 1 1 1 1 1> /* 2 sample average */
I went through 12.3.3 of the AM3358 Technical Reference Manual and it
seems that the setting the averaging
Hi John,
Thanks for the help, I looked into the iio_generic_buffer.c example and i
patched it to disable the hardware triggers thanks to the patch presented
on this page : https://www.teachmemicro.com/beaglebone-black-adc/ I am now
able to reader a buffer from the different channel.
However I
Hi John,
Sorry for the late answer, I had hard time using the PRUs and I am now
going to use the IIO ADC driver, I am able to read the sample with the cat
command in /sys/bus/iio/devices/iio:device0/in_voltage3_raw
However I am not able to use Libiio in order to read data from a user space
UART4 sorry for the typo, I am loading BB-UART4-00A0.dtbo not the UART2
one.
The config-pin solution is working thanks a lot!!
However, do you know why it is not working with the device tree? I would
like to understand the problem
It seems that when I load a device tree it prevents somehow
Hello,
I just wanted to tell you that I am encountering a similar issue, maybe the
description of it can help.
I wanted to use UART4 to send information to an Xbee radio, I am enabling
it by loading the 3BB-UART2-00A0.dtbo3 in uEnv.txt :
###Master Enable
enable_uboot_overlays=1

Thanks John,
I am now working with the starterware_PRU but I did not find examples for
using the McSPI with the PRU, do you think it will be hard to adapt the
initial code to the PRU ?
Thanks

Thanks John for you answer, I was quit busy last week so I worked on this
during the Weekend.
Unfortunately, I was not able to find a project that is using the SPI and
I2C interface with the PRU, I only found this one :
Thank you for your quick answerJohn!
So if I understand well, I can use the PRUs with the on-board SPI and I2C
interface ? I have not found any similar project that can help me on this.
Is it done using the L2 and L3 interconnect ? I am highly interested by
using those on board interface
Hi all,
I am trying to use the PRUs for real time data acquisition on the
Beaglebone black (Linux debian 4.9.45-ti-r57). I have set up the PRU with
remoteproc and RPMsg; everything is working fine.
The first time, I successfully captured data with the PRU using the SPI
protocol and bit
Hi,
OK, I missed it when reading the pot's documentation, my bad.
Could you tell me what is the code for the SPI(x,y) function/library you
are using on the BeagleBone ? I used SPI between PRUs and an accelerometer
once, and I encourtered a similar problem, which finally came form the SPI
Hi RoSchmi,
I am using the PRU with RPMsg for a school project, I have just made a
documentation about how to set it up:
https://github.com/PierrickRauby/PRU-RPMsg-Setup-BeagleBoneBlack
I maybe out off the track with this answer but I hope it help.
Thanks

I maybe of the track, but the AD 8403 seems to be a 3 wire SPI, then I do
not understand why your setting up 4 pins on the BBB
