An image of this EPROM is alsoprovided at <TTCLASS="FILENAME">loaders/powerpc-mbx/gdbload.bin</TT> underthe root of your eCos installation.</P><P>The EPROM is installed to socket XU1 on the board. Attentionshould be paid to the correct orientation of the EPROM during installation.Only replace the board"s existing ROM using a proper PLCCextraction tool, as the socket would otherwise risk getting damaged.</P><P>The GDB stub in the EPROM allows communication with GDB usingthe serial port at connector SMC1/COM1. The communicationparameters are fixed at 38400 baud, 8 data bits, no parity bit and1 stop bit (8-N-1). No flow control is employed. Connection to thehost computer should be made using a suitable serial cable.</P><P>In order to make the board execute the EPROM that you justinstalled (rather than the on-board FLASH memory), it may be necessarymove some links on the board. Specifically, ensure that link J4is in position 1-2. If in doubt, refer to the MBX documentationfrom Motorola, ensuring that Boot Port Size=8 Bits/ROMfor BOOT (CS#7), in their terminology.</P><DIVCLASS="SECT2"><H2CLASS="SECT2"><ANAME="AEN3422">Installing the Stubs into FLASH</H2><DIVCLASS="SECT3"><H3CLASS="SECT3"><ANAME="AEN3424">Preparing the Binaries</H3><P>These two binary preparation steps are not strictly necessaryas the eCos distribution ships with pre-compiled binaries in thedirectory <TTCLASS="FILENAME">loaders/powerpc-mbx</TT> relative to the installationroot.</P><DIVCLASS="SECT4"><H4CLASS="SECT4"><ANAME="AEN3428">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 PowerPC Motorola MBX860/821hardware.</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.
