+><P
+>The eCos Developer’s Kit package comes with a ROM
+which provides GDB support for the Hitachi EDK7708 board (a big-endian
+and a little-endian version). Images of these ROMs are also provided
+at <TT
+CLASS="FILENAME"
+>loaders/sh-edk7708/gdbload.bin</TT
+> and
+ <TT
+CLASS="FILENAME"
+>loaders/sh-edk7708le/gdbload.bin</TT
+> under
+the root of your eCos installation.</P
+><P
+>The ROM is installed to socket U6 on the board. When using
+the big-endian ROM, jumper 9 must be set to 2-3. When using the
+little-endian ROM, jumper 9 must be set to 1-2. Attention should
+be paid to the correct orientation of the ROM during installation.
+Only replace the board"s existing ROM using a proper PLCC extraction
+tool, as the socket would otherwise risk being damaged. </P
+><P
+>If you are going to program a new ROM or FLASH using the binary
+image, you may have to experiment to get the right byte-order in
+the device. Depending on the programming software you use, it might
+be necessary to enable byte-swapping. If the GDB stub ROM/FLASH
+you program does not work, try reversing the byte-order.</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 the dedicated serial cable included in the EDK package. </P
