Free Electrons recently posted the following resources: Videos of the Embedded Linux Conference Europe 2012 Videos of the Embedded track at FOSDEM 2012 As usual the conferences are full of interesting projects and information. My highlights for personal interest are: Wolfram Sang (Pengutronix e.K.) Maintainer’s Diary: Devicetree and Its Stumbling Blocks Slides; Video (49 minutes): full HD (329M), 800×450 (160M) Peter […]
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 […]
This is a tutorial to:
1. Get Linux kernel 3.2 source code
3. Configure and compile for Versatile Express ARM Cortex-A9 platform
4. Prepare and create a ramdisk using initramfs schema
5. Emulate kernel boot and ramdisk execution using QEMU
For anyone interested, the schedule for the next Embedded Linux Conference, held in San Francisco bay on the 15-16-17 of February, is out: 2012 Embedded Linux Conference | Schedule | Linux Foundation Events.
In this post I suggest a way to have an encrypted Linux installation on a USB key, which to me is useful when I travel and I want to securely access the functionality that desktop Linux offers. I want to have no fear that what I take with me will be stolen, even if what I take with me is a full Linux OS, together with my data and maybe some online passwords saved in the browser.
I noticed that on my Debian Testing installation the system beep is active, even though my computer has a nice and common integrated sound card. To disable the annoying beeps at start-up and shut-down, the common solution is to blacklist the “pcspkr” module, which is responsible for the beeping noise. I noticed that most advices […]
As usual, FreeElectrons hosts the videos of the Embedded Linux Conference Europe, together with the presented material: Embedded Linux Conference Europe 2011 videos Here is a personal selection of videos that I find most interesting: Linus Torvalds, Alan Cox, Thomas Gleixner, Paul McKenney moderated by Lennart Poettering Kernel Developer Panel Video (55 minutes): full HD […]
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 […]
While looking for existing C coding standards I discovered that the GNU and Linux projects officially suggest very different styles. Inside the Linux kernel documentation, Linus Torvalds goes so far as to mock GNU coding standards: First off, I’d suggest printing out a copy of the GNU coding standards, and NOT read it. Burn them, […]
The videos of the presentations held at the Embedded Linux Conference 2010 have been recently made public on Free Electrons. I was particularly interested in one speech: Custom Hardware Modeling for FPGAs and Embedded Linux Platforms with QEMU (PDF slides and OGV video). John Williams (PetaLogix) illustrates the work they have been doing on reducing […]
