Examples are in + <TT +CLASS="FILENAME" +>dejagnu/baseboards</TT +>. Usually to make a new + board file, it's easiest to copy an existing one. It is also + possible to have your file be based on a + <I +CLASS="EMPHASIS" +>baseboard</I +> file with only one or two + changes needed. Typically, this can be as simple as just + changing the linker script. Once the new baseboard file is done, + add it to the <SPAN +CLASS="SYMBOL" +>boards_DATA</SPAN +> list in the + <TT +CLASS="FILENAME" +>dejagnu/baseboards/Makefile.am</TT +>, and regenerate the + Makefile.in using automake. Then just rebuild and install DejaGnu. You + can test it by:</P +><P +>There is a crude inheritance scheme going on with board files, so + you can include one board file into another, The two main procedures used + to do this are <TT +CLASS="FUNCTION" +>load_generic_config</TT +> and + <TT +CLASS="FUNCTION" +>load_base_board_description</TT +>. The generic config file + contains other procedures used for a certain class of target. The + board description file is where the board specfic settings go. Commonly + there are similar target environments with just different + processors.</P +><DIV +CLASS="EXAMPLE" +><A +NAME="AEN1224" +></A +><P +><B +>Example 6.
