An image of this EPROM is also provided at <TT CLASS="FILENAME" >loaders/vr4300-vrc4373/gdbload.bin</TT > under the root of your eCos installation.</P ><P >The EPROM is installed to socket U12 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 J1. 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 straight-through serial cable. </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="setup-tx49-ref4955.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-vr4300-vrc4375.html" ACCESSKEY="N" >Next</A ></TD ></TR ><TR ><TD WIDTH="33%" ALIGN="left" VALIGN="top" >TX49 Hardware 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" >VRC4375 Hardware Setup</TD ></TR ></TABLE ></DIV ></BODY ></HTML >
