    2222=== Tool selection ===
     23The [http://www.angstrom-distribution.org/ Linux Angstrom Distribution] was selected as the Operating System. The benefit of Angstrom is that it is working well on the beagleboard, additional software can be easily installed from the repository provided by the distribution and using the Qt Embedded Linux external toolchain one can easily compile Qt and other software for Angstrom.

     25[http://oprofile.sf.net OProfile] was choosen for profiling as it is included in the kernel by default and has ARMv7 support. One requirement for it to generate calltraces for userspace application is that they were compiled using the `-fno-omit-frame-pointer` switch. Angstrom is created by using [http://openembedded.org OpenEmbedded] which allows to easily recompile the distribution with different compiler flags. In this case the whole distribution was built with `-fno-omit-frame-pointer`.
