Get valuable embedded Linux experience using our practical labs on a Beagle Board.
We were asked to customize our
embedded Linux training session
with specific labs on OMAP 3530 hardware. After a successful delivery on the customer site, using
Beagle boards
, here are our training materials, released as usual under the terms of the
Creative Commons Attribution-ShareAlike 3.0 license
:

• Lecture slides (
  PDF
  ,
  ODF
  ): the same slides as in our
  embedded Linux
  sessions.
• Lecture table of contents (
  PDF
  ,
  ODF
  )
• Practical labs (
  PDF
  ,
  ODF
  ), with specific instructions for the Beagle Board.
• Training agenda: (

If you are the happy owner of such a board (both attractive and
cheap), or are interested in getting one, you can get valuable embedded
Linux experience by reading our lecture materials and by taking our
practical labs.
Here’s what you would practise with if you decide to take our labs:

• Build a cross-compiling toolchain with
  crosstool-NG
  
• Compile U-boot and the X-loader and install it on MMC and flash storage.
• Manipulate Linux kernel sources and apply source patches
• Configure, compile and boot a Linux kernel for an emulated PC target
• Configure, cross-compile and boot a Linux kernel on your Beagle Board
• Build a tiny filesystem from scratch, based on BusyBox, and with a web server interface. Practice with NFS booting.
• Put your filesystem on MMC storage, replacing NFS. Practice with SquashFS.
• Put your filesystem on internal NAND flash storage. Practice with JFFS2 too.
• Manually cross-compile libraries (zlib, libpng, libjpeg, FreeType
  and DirectFB) and a DirectFB examples, getting familiar with the tricks
  required to cross-compile components provided by the community.
• Build the same kind of graphical system automatically with
  Buildroot
  .
• Compile your own application against existing libraries. Debug a
  target application with strace, ltrace and gdbserver running on the
  target.
• Do experiments with the rt-preempt patches. Measure scheduling latency improvements.
• Implement hotplugging with mdev, BusyBox’s lightweight alternative to udev.

Note that the labs were tested with Rev. C boards, but are also
supposed to work fine with Rev. B ones. You may also be able to reuse
some of our instructions with
other boards with a TI OMAP3 processor
.
Of course, if you like the materials, you can also ask your company
to order such a training session from us. We will be delighted to come
to your place and spend time with you and your colleagues.
