The current implementation provides accurate simulation of the instruction set, interrupt controller, timers, and serial I/O.</P ><P >In this release, you can run the same eCos binaries in the simulator that can run on target hardware, if built for ROM start-up, with the exception of those that use the watchdog timer.</P ><P >However, note that AM33 devices required to run eCos are not simulated; therefore you cannot run eCos binaries built for the AM33 under the simulator. For the AM33, the simulator is effectively an instruction-set only simulator.</P ><P >To simplify connection to the simulator, you are advised to create a GDB macro by putting the following code in your personal GDB start-up file (gdb.ini on Windows and .gdbinit on UNIX).</P ><TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >define msim target sim --board=stdeval1 --memory-region 0x34004000,0x8 rbreak cyg_test_exit rbreak cyg_assert_fail end</PRE ></TD ></TR ></TABLE ><P >You can then connect to the simulator by invoking the command <TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >msim</PRE ></TD ></TR ></TABLE > on the command line:</P ><TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >(gdb) msim</PRE ></TD ></TR ></TABLE ><P >You can achieve the same effect by typing out the macro’s content on the command line if necessary.</P ></DIV ><DIV CLASS="NAVFOOTER" ><HR ALIGN="LEFT" WIDTH="100%"><TABLE SUMMARY="Footer navigation table" WIDTH="100%" BORDER="0" CELLPADDING="0" CELLSPACING="0" ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" ><A HREF="appendix-target-setup.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ecos-user-guide.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="setup-am33-stb.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >Target Setup</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="appendix-target-setup.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >AM33 STB Hardware Setup</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
