To work around this, either change the CONFIG_MEMORY_START kernel option to a higher address, or use the compressed kernel image and load it at a higher address. For example, setting CONFIG_MEMORY_START to 0x8c100000, the kernel expects to be loaded at address 0x8c101000 with the entry point at 0x8c102000.</P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN7348">Memory Maps</H2 ><P >RedBoot sets up the following memory map on the SE77x9 board.<TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >Physical Address Range Description ----------------------- ----------- 0x80000000 - 0x803fffff Flash (MBM29LV160) 0x81000000 - 0x813fffff EPROM (M27C800) 0x8c000000 - 0x8dffffff DRAM 0xb0000000 - 0xb03fffff Ethernet (DP83902A) 0xb0800000 - 0xb08fffff 16C552A 0xb1000000 - 0xb100ffff Switches 0xb1800000 - 0xb18fffff LEDs 0xb8000000 - 0xbbffffff PCMCIA (MaruBun)</PRE ></TD ></TR ></TABLE ></P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN7352">Ethernet Driver</H2 ><P >The ethernet driver uses a hardwired ESA which can, at present, only be changed in CDL.</P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN7355">Rebuilding RedBoot</H2 ><P >These shell variables provide the platform-specific information needed for building RedBoot according to the procedure described in <A HREF="rebuilding-redboot.html" >Chapter 3</A >: <TABLE BORDER="5" BGCOLOR="#E0E0F0" WIDTH="70%" ><TR ><TD ><PRE CLASS="PROGRAMLISTING" >export TARGET=se77x9 export ARCH_DIR=sh export PLATFORM_DIR=se77x9</PRE ></TD ></TR ></TABLE ></P ><P >The names of configuration files are listed above with the description of the associated modes.</P ></DIV ></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="edk7708.html" ACCESSKEY="P" >Prev</A ></TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="ecos-ref.html" ACCESSKEY="H" >Home</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" ><A HREF="hs7729pci.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >SuperH/SH3(SH7708) Hitachi EDK7708</TD ><TD WIDTH="34%" ALIGN="center" VALIGN="top" ><A HREF="installation-and-testing.html" ACCESSKEY="U" >Up</A ></TD ><TD WIDTH="33%" ALIGN="right" VALIGN="top" >SuperH/SH3(SH7729) Hitachi HS7729PCI</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
