<TITLE>How I made my BSP support multiple memory maps</TITLE>
</HEAD>
<BODY>
<P><FONT SIZE=2>Many thanks to all of those who sent suggestions. Since my application</FONT>
<BR><FONT SIZE=2>is pretty simple (support two different target memory sizes via a switch</FONT>
<BR><FONT SIZE=2>at application compile time), I went with the simple trick of having</FONT>
<BR><FONT SIZE=2>two targets in the application makefile which pass different options to</FONT>
<BR><FONT SIZE=2>the linker for locating the text section.</FONT>
</P>
<P><FONT SIZE=2>One target has this in its link flags:</FONT>
<BR> <FONT SIZE=2>-Wl,-Ttext -Wl,0xff000000</FONT>
</P>
<P><FONT SIZE=2>And the other has this:</FONT>
<BR> <FONT SIZE=2>-Wl,-Ttext -Wl,0xff800000</FONT>
</P>
<P><FONT SIZE=2>The text section comes first in the linkcmds, and the other sections are</FONT>
<BR><FONT SIZE=2>placed after it; the above link flags move the linked image to the right</FONT>
<BR><FONT SIZE=2>address.</FONT>
