Images of these ROMs are also providedat <TTCLASS="FILENAME">loaders/sh-edk7708/gdbload.bin</TT> and <TTCLASS="FILENAME">loaders/sh-edk7708le/gdbload.bin</TT> underthe root of your eCos installation.</P><P>The ROM is installed to socket U6 on the board. When usingthe big-endian ROM, jumper 9 must be set to 2-3. When using thelittle-endian ROM, jumper 9 must be set to 1-2. Attention shouldbe paid to the correct orientation of the ROM during installation.Only replace the board"s existing ROM using a proper PLCC extractiontool, as the socket would otherwise risk being damaged. </P><P>If you are going to program a new ROM or FLASH using the binaryimage, you may have to experiment to get the right byte-order inthe device. Depending on the programming software you use, it mightbe necessary to enable byte-swapping. If the GDB stub ROM/FLASHyou program does not work, try reversing the byte-order.</P><P>The GDB stub in the EPROM allows communication with GDB usingthe serial port at connector J1. The communication parameters arefixed at 38400 baud, 8 data bits, no parity bit and 1 stop bit (8-N-1).No flow control is employed. Connection to the host computer shouldbe made using the dedicated serial cable included in the EDK package. </P><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN4067">Installing the Stubs into FLASH</H2><DIVCLASS="SECT3"><H3CLASS="SECT3"><ANAME="AEN4069">Preparing the Binaries</H3><P>These two binary preparation steps are not strictly necessaryas the eCos distribution ships with pre-compiled binaries in thedirectory loaders/sh-edk7708 and loaders/sh-edk7708lerelative to the installation root.</P><DIVCLASS="SECT4"><H4CLASS="SECT4"><ANAME="AEN4072">Building the ROM images with the eCos Configuration Tool</H4><P></P><OLTYPE="1"><LI><P>Start with a new document - selecting the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">File->New</I></SPAN> menu item if necessary to do this.</P></LI><LI><P>Choose the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">Build->Templates</I></SPAN> menu item, and then select the SH EDK7708 hardware.</P></LI><LI><P>While still displaying the <SPANCLASS="emphasis"><ICLASS="EMPHASIS">Build->Templates</I></SPAN> dialog box, select the “stubs” package templateto build a GDB stub.
