Free Android training materials – Free Electrons blog. Free Electrons publishes another set of extremely useful materials that include instructional slides, source code and documentation. The objective of the course is to familiarize with Android from its lowest levels, using also this Devkit8000 embedded board. The (383) slides and the (24-pages-long) hands-on lab exercises are […]

ARM926 interrupts in QEMU

April 15, 2012


In this post I prepared what I think is the simplest example on how to manage interrupts for the widespread ARM926 core. From this example one can expand the complexity of the interrupt management at will. I’m going to test the functionality with QEMU, emulating the Versatile Platform Baseboard. I based this example on my […]

ELC 2012 videos and slides

April 7, 2012


Free Electrons posted the videos of the last Embedded Linux Conference 2012. Unfortunately most of the videos have really bad audio quality, so maybe this time reading the slides will be more effective. The most interesting topics for me are the following: The Kernel report Binary Blobs Attack!!! Status of embedded Linux Experiences With Device […]

Codesourcery toolchains have new site at Mentor Graphics

October 8, 2011


This completely slipped under my radar: Mentor Graphics acquired CodeSourcery’s toolchain products some time ago. I found out when I got to their site and it redirected me to Mentor. In my tutorials I often make use of the Lite editions of the Codesourcery toolchains, so this is the new site for reference: Sourcery CodeBench […]

Using CodeSourcery bare metal toolchain for Cortex-M3

September 3, 2011


Using the CodeSourcery arm-none-eabi toolchain to compile a minimal "Hello World" example for Stellaris lm3s6965 microcontroller. The microcontroller is emulated through QEMU and the output is written to a serial port.

Compiling Linux kernel 3.0 with Emdebian ARM toolchain

July 24, 2011


The Emdebian project works to bring Debian on embedded platforms, with repositories of custom distributions and toolchains to cross-compile software. I wanted to try their ARM toolchains, and coincidentally the Linux kernel 3.0 has been released in these days, so I tried to cross-compile it and emulate it on QEMU. These tests have been done […]
