Hi all,
I've done a few searches and couldn't find any threads or "conversations"
in this forum/group on the remoteproc kernel module for loading firmware
onto the PRUs.
The remoteproc framework is supposed to be a Linux standard, there are some
generic documents for it, but I've only found a
Thanks Thomas,
I'll look into your project, I had come across it before, but wanted to
first complete the TI hands on labs to get my mind around the basics.
I'll have a look further, though for basic pin configuration to test code,
are the config-pin and gpioinfo commands all one needs?
How does
Hi all,
I'm in the process of doing a project with the PRUs, only just started, and
learning how to do MUX and pad settings etc, using TI's hands on labs, plus
have seen some of your work Mark.
I'll be later using a 20 x 4 char LCD which is the same interface &
protocol.

Hi all,
I know this sort of topic has been discussed at different times, the
Kernel, Capemgr and slots files have changed over the time.
uBoot is supposed to manage device tree overlays or something, at it seems
that one has to reboot each time you want to change cape overlays.

Hi all,
I've tried following scripts etc in /opt/scripts and while a number of them
are used to control the boot and other processes of the board, I can't
follow how they are called.
Please can someone tell me from the Kernel being loaded how I can start to
follow the boot process?
Is this doc
Hi all,
I know of the official PRU cape from TI, this was from 2014, when the
BeagleBone Black came out, a long time ago.
I now have the BB-AI, while its most likely the cape is compatible, I'm
sure there must be something a lot more recent.
Is there at least a general purpose cape, which even
Hi all,
Thanks for your input, its very strange. I got it working, by pinging the
IP address from my laptop.
They are both connected to the same WiFi network. The routing table hasn't
changed at all, but I noticed that it took like 5 seconds to generate. I
assumed that might have been normal f
Hi all,
I'm also having issues with getting internet via WiFi on this BB-AI board.
It connects to my WiFi network, gets a DHCP address, the routing table
shows the default route is 192.168.1.1, through wlan0 interface etc,
exactly the same top line of Matt's table.
The WiFi LED goes green (righ
Hi all,
I see this was asked a few years ago, are there still no further plans to add a
multicore board to the lineup?
I ask as its very likely the company I work for would have ordered one if there
was, we use the PI 3 and its not 100% ideal, we would love an RTC, I know the

Hi Drew,
Thanks very much for your reply and info, I've previously seen your 2
YouTube videos showing your setup from a few years ago which gave me some
clues and I downloaded the same image you used then and saw it worked fine.
I had made a mistake by using 5v on the hall sensor as the datashe
Hi all,
I'm trying to use the eQEP Linux driver. I can get it to load by adding a
device tree overlay, but it doesn't increment much. I can see that its
loaded (called tieqep) with lsmod etc.
I've never used a quadrature encoder before, so I question if I just havn't
connected it correctly.
Hi all,
Those interested in embedded development with Simulink will be happy to
know that Mathworks released some form of official support for the
BeagleBone Black with version R2014b and a hardware support package.
I'll be trying that out when my university finally gets its which may take

Hi David,
Yes, I have also seen small boards from Adafruit, though if I need an RTC
and it is possible to implement a fully functional one with the current
board by just adding a battery, I wouldn't add any extra components,
especially since the RTC in the CPU seems to have wake up events.
I a
Hi all,
If one adds the feature in software, would it be physically possible to
have the realtime clock feature (with wake up events etc) if it is done
correctly in software?
Is the software implementation the only thing stopping RTC functionality

Hi,
My name is Fisher, I'm doing a Masters in control system research and need
to choose a controller board for my project.
It will control a 6 wheel car (wild thumper) to keep a rod (inverted
pendulum) upright.
I am looking to understand the BBB in more detail to know if I should
consider it
