Is it possible to use the BB as Mass Storage Device? I want it to be connected to an audio player that can read files from USB connectivity (such as USB flash drive) and act as data storage device containing one specific folder (and its sub-folders) from the file system (if possible, on a flash drive connected to the board.). As the device specs says, it has connectivity of: USB client for power & communications USB host Operating system will probably be Ubuntu but can be changed. What drivers or configurations needs to be done in order to achieve this? The latest images have already the mass

I've got caught in the not-so-sunny world of cross-compilation. I'm trying to compile a simple hello world application for my BeagleBone Black (which runs a TI Cortex-A8 processor). First of all, I compiled and ran successfully the hello world application on x86 with gcc Then I changed my compilation settings to the following: arm-linux-gnueabi-gcc -c -O0 -g3 -Wall main.c -o bin/obj/main.o arm-linux-gnueabi-gcc bin/obj/main.o -o bin/hello_world I transferred the file via SCP to the BeagleBone, and set executable permissions with chmod +x hello_world Upon running it ( ./hello_world ), my only

I am working on BeagleBone Black and Debian running on it. I want to flash latest Debian image on my board. To do so I have downloaded a latest Debian image from link: BeagleBone Image and prepared an SD card using WinDisk image writer. As per tutorial I have inserted an SD card into the BeagleBone Black, pressed boot button and applied power. SD card image has booted. According to the tutorial flashing eMMC takes about 30-40 minutes, so I waited for about 2 hours (just to be sure). Then I removed an SD card from my board and power it on. It booted my previous image (eMMC was not Flashed by SD

I'm having a bit of a weird issue here. Simply put, I'm trying to grab a frame from a camera (Mercury 2.0 Webcam embedded camera), but it's not going as expected. I'm running Debian Jessie on a BeagleBone Black. I've installed OpenCV 3.2 and tested it, my Vision algorithm is working fine with imread(), so it's time to start using the camera. The first issue I encountered was the camera not working in Ubuntu 16.04 minimal. So I switched to Debian Jessie and now I can grab 1600x1200 frames using fswebcam (fswebcam -r 1600x1200 --jpeg 95 -D 0 test.jpg) in a fraction of a second, as expected. I

I don't understand what is the reason of buildroot of a card such as beaglebone black where as it has a Linux system when we bought.What is the utility of the buildroot? Build a completely custom, lightweight, and fast-booting embedded Linux system? Buildroot is a set of Makefiles and patches that makes it easy to generate a complete embedded Linux system . Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a bootloader image. It is useful mainly for people working with small or embedded systems, using various CPU architectures (x86, ARM,

I am working on two Beaglebone Black with Xenomai and RTnet. I have two c-files for a roundtrip ethernet frame between the BBB's. When I try to compile the first c-file there occur some errors: undefined reference to 'rt_task_self' rt_task_self is a function in my c-file and is declared in my headerfile "task.h". So in my opinion "undefined" means that it is just not defined in any cpp-file "task.cpp" for the headerfile "task.h". But I am a little bit confused: How do I tell my program that my headerfile "task.h" is defined in my other file "task.cpp" or "task.o" or... I have many header files
