>The eCos Developer&#8217;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&quot;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
