Hey, does anyone know if there's a flashable Lubuntu disk image for the BBB?

Check out RCN-EE's guides on building your own images. Those cover Ubuntu too.

Powered with a Beagle Bone Black inside it.
 
The 3040 CNC machine is the world's most popular low-cost rigid CNC, but nobody in the maker community knows about it...until now. Go get one for yourself and use ChiliPeppr on it with a TinyG.

Received my Logic 4!  Installed the software ("Logic") and took some samples of my SPI signals for the Pinball project. This sample is from the score display (10 digits, driven by 2 74hc595. One 74hc595 sets two lines high to select which of the 10 digits to provide power, while the other provides the bits for turning on the LED of the 7 segment display). 

As you can see by this pattern it's interpreted as 00001100 (Position 5), 10101110 (digit 1 with decimal point). So Position 5 on the score display contains a 1. [The display is currently showing a date/time string with the point segmenting the display]

Using the Logic 4 I was able to identify a gap in the signal which was the result of the code sending the data as two independent bytes, I modified the code to send them as a single set of 16 bits, with the gap in the signal being eliminated. I was also able to identify the need to then swap the 2 bytes to get the correct results. 

I'll be modifying the actual code on the Beaglebone to use the PRUs in the future, the Logic Analyzer will be useful in verifying what is happening with the outputs. I'll be able to use the output to diagnose any errors in the SPI output.

We have one of these at work and it's absolutely one of my favorite tools. Every time I have a project with digital signals, this is the first thing I break out.

Can I connect the serial port of the BeagleBone to a Raspberry for serial communication without voltage shifting?

I need to access the serial console of my BeagleBone Black. Since this console uses 3,3 Volts, and the Rapsberry GPIO pins are also on 3.3 Volts, I was wondering if I could use a Raspberry Pi for this.

So could I connect two or three pins from the BeagleBone to the Rapsberry and have functional serial communication? Is there anybody who has done this?

About this community

As embedded-computing enthusiast and as a fresh owner of a Beaglebone Black device I want to share with other developers my comments about the platform.

Does anyone know what ' led_aging.sh' is, and why it is on my BBB?

Honestly, I should have just clobbered the pre-installed junk and installed base debian to the mmc like I normally do, but I had hopes that a stock install would suit my needs.

I'm working with a new LCD that requires loading SPI data on startup.  Is there an easy way to handle this via the DT file?

I needed some space quickly to back up a few TB of data. A BBB connected to 4TB USB drive with rsync, samba and NFS services rocks. Do like this little board. Throughput is fine for what I need it for.
It was BBB on next day delivery or Pi2 on back order..  glad I chose not to wait.

Ethernet hardware:    The Raspberry ethernet is connected internally on a USB hub the same as his disk.   
  http://www.raspberrypi.org/help/faqs/#networkingNoGig

I checked and both are 10/100 ethernet.. so the issue is the sharing of the USB hub (I misspoke about GigE,
GigE is not in this game but a great switch can always help).

I just tried some things with my new  day old quad core Raz-Pi and it is quicker than the BBB.

Time to run "lmbench" on the two side by side.

Hi Fabio,
there is one problem with that version: i have no option for PWM-Pulses. The rest will be ok with that board.

Dear BBB community,

I am unable to power my BBB, Rev. A5A, using the barrel connector. While powering the device over USB and booting from an attached SD card works without a problem, the BBB does seem to ignore my switching power supply (5V, 2250mA) plugged into the barrel connector. All LEDs remain dark. Pressing either of the buttons yields no reaction, too . The power supply works with other (non-BBB) devices.

Does anyone have an idea what I am doing wrong? I am thankful for any advice.

From ubuntu.com/things#try-beaglebone:
While we are working with many platform partners out there to ensure that your platform of choice becomes readily available, we have picked the Beaglebone Black as our first device to get started.
A new, transactionally updated Ubuntu for clouds and devices.
