|Embedded Linux Learning Kit version 3
turns out that there are two versions of the Matrix Compact Kit board
in circulation. There are three GPIO bits that differ between Rev. A
and Rev. B. So if the led program doesn't work for you, then you've probably got Rev. A. Here are the differences:

three files that are affected by this issue. Copy the two .c files to
pi-lib/ and copy the .h file to includes/.

Linux Learning Kit Software Installation Problem
has shown up in the install_tools.sh script when run under
Ubuntu. The symptom is that the install.sh
can't create or populate the .working/
uses the LOGNAME
environment variable to change the ownership of target_fs/home and
everything in it. LOGNAME
is initially set to the user name you log in as. Under Fedora
and Red Hat distros, when you su
or sudo to
become root, LOGNAME
retains its initial value. However under Ubuntu, when you
become root the value of LOGNAME
changes to "root", which kind of defeats the purpose.
workaround is to manually change the ownership of home/ and
everything under it to your user name, create home/.working/ and
copy the files from the CD. Do this as root of course.
