Locux: 15 USD Freescale i.MX233 System On Module

These days, low cost boards seem to pop-up a bit everywhere…  Featuring the same processor as Olimex OLinuXino, the Locux board will be powered by a Freescale i.MX233 with 64 MB and boot from a microSD card (no NAND on the board). This project is quite different from other low cost board projects, since it is a system on module (SoM) and will require a carrier board to access peripherals such as Ethernet, USB Host and video output, although  the developers managed to boot it with a simple breadboard. The developers also explain that this board stands apart as it does not feature any BGA parts and can be hand soldered, which could be an advantage when sourcing the boards and some hobbyist may also like to do the soldering themselves. The Raspberry Pi is still hard to get and the some other low cost boards such as the Beaglebone […]

Cross-compiling the ARM Linux Kernel in Ubuntu 12.04 LTS

Yesterday I installed Ubuntu 12.04 ‘Precise’ Beta 1 in Virtual Box to give it a try (I could not manage to have HUD working btw), and today, I’ve noticed an article entitled “Ubuntu 12.04 ‘precise’ and cross compilation of ARM kernels” explaining how to build Linaro ARM kernel in Ubuntu 12.04. So I’ve decided to give it a try, especially it seems straightforward. I followed the instructions in the aforementioned link,  it basically worked except I had to install dpkg-dev package that also installed the build essentials (gcc, g++, etc…) and use sudo for some commands. You’ll notice the name change for the ARM gcc toolchain as it now uses hard-float by default which seems to provide quite a boost in performance for the Pandaboard. Here are the steps I followed: Install the ARM GCC cross compiler and the development package of dpkg:

Retrieve the kernel source:
