This system is usually a Linux box; however, the CoLinux port of the Blackfin tool chain makes it possible to use a machine running Windows as well. The development system should have an available serial port, terminal emulator software, and an Ethernet card. The Blackfin tool chain is installed on the development system and used to compile Blackfin programs which are then loaded onto the target hardware.</p></div><!-- SECTION [30-586] --><h3><a name="target_hardware" id="target_hardware">Target Hardware</a></h3><div class="level3"><p>This is usually some type of Blackfin development board. There are several options available for the target hardware platform such as the ADDS-BF533-STAMP or ADDS-BF537-STAMP board. This document focuses on the STAMP board; however, most of the procedures described are also applicable to other target hardware platforms. When using other target hardware platforms usually only the memory addresses given in this documentation need to be changed.</p></div><h4><a name="minimum_requirements_of_a_blackfin_based_uclinux_system" id="minimum_requirements_of_a_blackfin_based_uclinux_system">Minimum Requirements of a Blackfin Based uClinux System</a></h4><div class="level4"><p>The minimum configuration for a Blackfin based Linux product varies widely, depending on what the kernel is loaded with. For example - uClinux kernels can be run in less than 4Meg of Memory, and if a large storage is needed, a hard drive can be connected, and the uClinux image can be run from here.</p><p>The validated hardware includes:</p><ul><li class="level1"><div class="li"> <a href="bf533-stamp_board.html" class="wikilink1" title="bf533-stamp_board.html">BF533-STAMP Board</a></div></li><li class="level1"><div class="li"> <a href="bf533-ezkit_board.html" class="wikilink1" title="bf533-ezkit_board.html">BF533-EZKit Board</a></div></li><li class="level1"><div class="li"> <a href="bf537-stamp_board.html" class="wikilink1" title="bf537-stamp_board.html">BF537-STAMP Board</a></div></li><li class="level1"><div class="li"> <a href="bf537-ezkit_board.html" class="wikilink1" title="bf537-ezkit_board.html">BF537-EZKit Board</a></div></li><li class="level1"><div class="li"> <a href="bf561-ezkit_board.html" class="wikilink1" title="bf561-ezkit_board.html">BF561-EZKit Board</a></div></li></ul><p> Always check what kind of <a href="serial_cable.html" class="wikilink1" title="serial_cable.html">serial cable</a> is needed before asking for help.</p></div><!-- SECTION [587-1667] --><h3><a name="daughter_cards" id="daughter_cards">Daughter Cards</a></h3><div class="level3"><p>Several daughter cards are currently being developed for the STAMP board. These cards provide features such as audio and video codecs, interfaces to standard connectors, and data acquisition capabilities.
