<p>
The tests are run twice. Once on the host (<code>bfin-elf</code> with newlib testing on the simulator) and another running on the Blackfin hardware (<code>bfin-uclinux</code> with uClibc on uClinux). For details on the testing, see how <a href="testing_the_toolchain.html" class="wikilink1" title="testing_the_toolchain.html">Testing the Toolchain</a> was done. Differences between running on uclinux/uclibc and simulator/new-lib usually means an issue in the kernel or library not in the toolchain.
