Cartesian Motion Platform. BeagleBone with Ubuntu | Flesh and machines. I know you gonna love me. This tutorial is a mix of several descriptions of how to set up BeagleBone on Ubuntu. There are several methods to do so. The easiest one when usb is connected: mzperx@geburah:~$ screen /dev/ttyUSB1 115200 ttyUSB1 depends on what you have connected to your computer, try some from `ls /dev/ttyUSB*` If your BeagleBone is connected to the same network as your computer (ie: you plugged it into your router using a UTP cable), you can try to locate it using a networking tool or try to connect to it using it’s default address: 192.168.7.1. If not, you can try the USB method and running ifconfig to see what ip the device received from the DHCP server of your router. Mzperx@geburah:~$ ssh root@beaglebone.local If not, you can go for the ifconfig method and connect using the pure IP. mzperx@geburah:~$ ssh root@192.168.0.172 The default root password on the BeagleBone is “root”.

March 21, 2012 AT 11:34 am Ubuntu on the BeagleBone with Userland SPI @ waxpraxis. After a couple of months of searching, reading, patching, and compiling, I finally have managed to get a build of linux working on the BeagleBone with userland SPI that you can access through the file system.The path was paved for me by an excellent tutorial by Brian Hensley on how to get the BeagleBone’s big brother, the BeagleBoard xM running with userland SPI. I figured out how to modify his instructions for the bone and combined it with a patch by Craig Berscheidt I found on the BeagleBoard mailing list (which I had to re-create for the 3.2 kernel). I’m going to be working on getting a full tutorial up, but since that may take me a week or more I figured I’d first share an image of my working system.

Introduction The TI OMAP/AM/DM SGX Graphics Driver is closely tied to the environment it is running under, and the configuration it is built with. This article mentions debugging methods specific to Linux. Baselining the current SGX driver environment The current SGX driver environment on the target can be observed using the below script.
This script performs the below actions: #! Build time configuration of the SGX driver The SGX driver can be configured for debug or release mode. Details of how to build the driver in these modes is provided in the below link. Debug mode operation In the debug mode of operation, the SGX driver keeps track of different states and logging information. Typical output (first few lines) of the Debug mode dump is shown below: Release mode operation /etc/powervr.ini 1. 2.
Review of Beaglebone. Introduction As a hobbyist and someone who likes developing proof of concept systems for commercial products, I like the BeagleBone. With its numerous accessible I/O ports and it's snappy AM3359v processor, it is a great board for prototyping new devices. Good stuff... That said, my road was a bit rocky with respect to installing, upgrading and developing with the BeagleBoard. The system I was evaluating the BeagleBone on was an ASUS G74S with an i7-2670QM, 16GB RAM and a 250GB SSD running Windows 7 64-bit. My original intent was to test/evaluate the board by porting a simple application to monitor & control a multi-zone home heating system remotely to the BeagleBone. Packaging The BeagleBone was delivered with: · the BeagleBone · a USB cable · a micro SD card already inserted in the BeagleBone (the label has worn off) · a micro SD labeled 'Linux SDK' · a micro SD to SD adapter The board that I received was revision A3, which is a year & a half old.
Installation Cloud 9 IDE Gate One opkg update. Toolchain Advenures 2: TI Code Composer on the Beaglebone | Arielli. Continuing yesterday’s effort to install CCS (apparently successful). Referring back to Getting started with JTAG and CCS I see from an illustration that it has you choose Target Configurations from the View menu. The Target Configurations tab I discovered reappears, then click the Refresh button.
Looking ahead I see that I’m probably expected to find some sort of representation of bbone-target-config-.ccxml in the User Defined folder. I right-click the folder hoping to find where it expects to find the files. I see an Import Target Configuration entry on the context menu, so I click it and find bbone-target-config-.ccxml already in the C:\ti\ccsv5\ccs_base\common\targetdb\configurations folder. I double-click the filename and a “File Operation” dialog appears saying “Select how the files should be imported” and gives me the options to “Copy files” or “Link to files”.
It now appears under the “User Defined” folder. As their illustration shows, CCS halted the processor (an emulator? Beaglebone startup script weirdness / associating with a WPA access point at boot. Thanks! But naturally this brings up the next question: how the heck can I get connman to recognize the wifi interface? Running the get- services script as described in the linked blog post only turns up the ethernet interface ( Adding -W wext to the init.d/connman script doesn't improve matters. There's also still the question of why my startup scripts are failing to successfully touch that debug file.
I will eventually need to have a non-wifi-related startup script run; right now I don't understand why it wouldn't.

BONE_SRM.pdf (application/pdf Object) Adventures with smalltalk and robots. Smalltalk on the BeagleBone If you've ever struggled with (or simply tired of) the tedious code-compile-upload-boot-test-debug-code-compile... cycle of creation on the arduino, this may be the platform you were looking for.
Running Squeak smalltalk on the BeagleBone allows you to create your software and interact with your hardware while it is running. Smalltalk is an easy to use programming environment that also happens to be very powerful. It is used for everything from embedded devices, educational programming, and 3D Online Worlds to semiconductor manufacturing, stock trading, and international shipping. For this quick introduction, I'm going to show how to connect a photoresistor to the BeagleBone and display it's value in a real-time graph, in 11 lines of code. To follow along you will need to have: I'm going to use option 3 for this demo, since is easy and can be done without modification to any of the software we are using.
The BeagleBone pin connections are as follows: Step 3: Play.
