An image of this EPROM is also provided at <TT CLASS="FILENAME" >loaders/powerpc-mbx/gdbload.bin</TT > under the root of your eCos installation.</P ><P >The EPROM is installed to socket XU1 on the board. Attention should be paid to the correct orientation of the EPROM during installation. Only replace the board"s existing ROM using a proper PLCC extraction tool, as the socket would otherwise risk getting damaged.</P ><P >The GDB stub in the EPROM allows communication with GDB using the serial port at connector SMC1/COM1. The communication parameters are fixed 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 should be made using a suitable serial cable.</P ><P >In order to make the board execute the EPROM that you just installed (rather than the on-board FLASH memory), it may be necessary move some links on the board. Specifically, ensure that link J4 is in position 1-2. If in doubt, refer to the MBX documentation from Motorola, ensuring that Boot Port Size=8 Bits/ROM for BOOT (CS#7), in their terminology.</P ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="AEN3422">Installing the Stubs into FLASH</H2 ><DIV CLASS="SECT3" ><H3 CLASS="SECT3" ><A NAME="AEN3424">Preparing the Binaries</H3 ><P >These two binary preparation steps are not strictly necessary as the eCos distribution ships with pre-compiled binaries in the directory <TT CLASS="FILENAME" >loaders/powerpc-mbx</TT > relative to the installation root.</P ><DIV CLASS="SECT4" ><H4 CLASS="SECT4" ><A NAME="AEN3428">Building the ROM images with the eCos Configuration Tool</H4 ><P ></P ><OL TYPE="1" ><LI ><P >Start with a new document - selecting the <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >File->New</I ></SPAN > menu item if necessary to do this.</P ></LI ><LI ><P >Choose the <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >Build->Templates</I ></SPAN > menu item, and then select the PowerPC Motorola MBX860/821 hardware.</P ></LI ><LI ><P >While still displaying the <SPAN CLASS="emphasis" ><I CLASS="EMPHASIS" >Build->Templates</I ></SPAN > dialog box, select the “stubs” package template to build a GDB stub.
