Hi Chris Many of the RF SoC can be Initialized via UART by sending AT commands
if that's what you are asking ??? I have used a windows python script to send
the AT commands to get the Soc eval board running If that's what you are asking
the script itself will run from the BB command prompt and
I used LXDE and modify the autostart to operate in kiosk mode.
Comment out the lxpanel and pcmanfm.
create a shell script (startmyapp.sh) in the home directory that will set up
any environment variables you need and launch your application:
sudo nano /etc/xdg/lxsession/LXDE/autostart
And make

Hi, I'm an engineering student and for my final project I'm working with
sensor fusion and computer vision algorithms for pose estimation. I would
like to use the PRUs on my BeagleBone Black for the sensor fusion part,
given the strict realtime requirements of my application but I find it to
Hi,
I am trying to debug a weird behavior.
I have code running on PRU 1 that creates a specific waveform on 8 pru
output pins (pru1_0 - pru1_7).
I am trying to confirm the accuracy of my PRU 1 code by running code on PRU
0 that watches the pins on PRU 1 (physically linked) and measures their
You should really have your test equipment running in a different clock
domain than your device under test, and then trigger off your unit under
test.
Very small phase or time differences between the unit under test and the
test equipment can lead to major data differences.
You are trying to
Thanks Graham.
Yeah, I know. The thing is that having the two share the same chip makes
things really fast. In my app I need to make about 125M different
measurements, so the difference between a 1ms test and a 10ms makes a huge
difference.
In fact, I don't need accuracy down to a single
Thanks so much guys.
The suggestion of using two BBB is great for getting the test program off
the same clock domain. The issue there for me is speed. The easy way to
get two BBBs working together would be to have them talk via ethernet.
This would be quite slow compared to my current setup
Bill:
I don't think the PRU clocks are externally available.
I don't know what your interface looks like, but if there was a clock line
involved in the data transfer, or marking when data is valid, I would look
at inverting or adding some delay in that line going to the receiving PRU.
If your
A few other bits of information is needed to get to the bottom of this.
- When you run the code on PRU0, what is running on PRU1? Do you put it in
reset or at least have it doing something that cannot interfere?
- Is everything in the local memory to the PRU in use or in the shared memory?
- Is

Hi, Everyone:
I'm going to setup a cross-toolchain of BBB for developers using CentOS or
Windows.
I have read the Cross *Toolchain* for Debian Wheezy
Fascinating! Thanks guys.
Graham,
Frequency counting is exactly what I am trying to here, and +-1 is exactly
what I am seeing, so that makes perfect sense. I was not aware that the PRU
clocks were physically available on the BBB! What fun! Where can I find
the leads to mess with? Perhaps I

Could you use a second BBB as the capture device instead? That would isolate
the PRUs from each other and possibly allow for the HW capture that was
mentioned.
