Duplicate/Restore ARM Linux Image to MMC/SD Card (BeagleBoard and DevKit ARM)

In ARM Linux on 25 March 2013 with no comments 2094 views

By booting from MMC/SD card, you can bring up your BeagleBoard-xM or DevKit8500D (both are ARMv7). It is the only way for the xM (microSD card to be exact), while with DevKit, you have the option to flash it to the board for NAND-boot once you’re sure that it works with SD card. eLinux wiki [...]

Raspberry Pi Common USB Problems

In ARM Linux on 24 March 2013 with 1 comment 6537 views

USB problem is the first thing to arise with Raspberry Pi when plugging-in peripherals. This isn’t exclusive though, learning that my Linux laptop also has it and the higher ARM architecture, BeagleBoard-xM, also experiences the same issue sometime. But with Raspberry Pi (RPi) in

Cross-Compiling for Ubuntu ARM by ffmpeg Example

In ARM Linux, Ubuntu on 5 November 2012 with 8 comments 7702 views

This has been a delayed post since I only figure out how to solve configure error just now. It wasn’t really necessary to cross-compile last year because compiling ffmpeg directly on the ARM-board finished overnight (despite the low CPU). Anyway, in this post I’m still using the board to easily retrieve package dependencies from Ubuntu [...]

Simple ffmpeg UDP Video Streaming (from BeagleBoard running Ubuntu)

In ARM Linux, Ubuntu on 5 November 2012 with no comments 16283 views

I really mean simple, this is a one command line UDP stream from the BeagleBoard (running Ubuntu ARM) to my desktop (IP address 192.168.1.19 in this example), the source video is an FLV file inside the ARM-board: $ ffmpeg -i UNIQLO_MIXPLAY.flv -v 0 -vcodec mpeg4 -f mpegts udp:192.168.1.19:1234 Although it’s a break-dance video, it plays [...]

Zabbix Proxy: distributed NMS monitoring via embedded Linux (Ubuntu on BeagleBoard)

In ARM Linux on 19 July 2012 with no comments 653 views

As already mentioned in previous post’s introduction, proof of concept on how Zabbix Proxy works under unreliable communication is what this next post about. The idea is to have these scenarios tested: independent SNMP data polling by individual NMS proxy (embedded system) intermittent connection between main/master NMS server with its proxy Of course we’ll do [...]

Compile Zabbix Proxy in Ubuntu ARM (BeagleBoard)

In ARM Linux, Ubuntu on 17 July 2012 with no comments 1488 views

I needed to tackle practical limitation of SNMP monitoring under unreliable communication, a serious consideration was made for Zabbix Proxy. It was an option said to be ready for embedded hardware. I already had BeagleBoard xM Rev C running Ubuntu 11.10 Oneiric and needed to proof that it would port functionally to this Linux ARM [...]

Ubuntu on Beagleboard xM with Easycap Video Capture (Compiling Driver)

In ARM Linux, Ubuntu on 31 December 2011 with no comments 1757 views

Attempt to run Ubuntu in BeagleBoard xM rev C board has taken me to try various options of kernel and release. The goal was to have both Ubuntu and widely-available Easycap as video input via the USB of this compact TI OMAP board. Porting Ubuntu would spare us some flexibility to try different alternatives of [...]

Hello World with JamVM Embedded JVM on Ubuntu ARM

In ARM Linux, Ubuntu on 12 December 2011 with no comments 1217 views

While waiting for my BeagleBoard xM shipment, I was considering Java as one of the possible application platforms. Anyhow, the keyword “embedded Java ARM” landed me to the tiny JamVm. This JVM is said to be working with ARM Cortex A8 which can be emulated under QEMU running Ubuntu ARM. The fact that there had [...]

Ubuntu ARM on QEMU Processor Emulator

In ARM Linux, Ubuntu on 27 November 2011 with no comments 1033 views

There are times when you need to try things on virtualized environment before hand e.g. 1) checking application functionality or 2) actual device shipment is still on its long way. Those were also my cases with ARM Linux. Unlike virtualization in production environment however, putting software to emulate CPU architecture will slow down the guest [...]

Running Ubuntu on DevKit8500D (Natty Kernel and Lucid RootFS)

In ARM Linux, Ubuntu on 28 October 2011 with no comments 976 views

BeagleBoard xM that comes with Texas Instruments’ DM3730 DaVinci™ processor has its Chinese sister from Embest, the DevKit8500D evaluation kit. This similarity and eLinux wiki (showing working previous DevKit8000) have made me confident that Ubuntu would also port to this board with no hassle. As always, that wasn’t the story. I tried preinstalled images available [...]
