>The eCos Developer's Kit package comes with an EPROM
which provides GDB support for the Cogent evaluation board. An image
of this EPROM is also provided at loaders/arm-cma230/gdbload.bin
under the root of your eCos installation. </P
><P
>The EPROM is installed to socket U3 on the board. Attention
should be paid to the correct orientation of the EPROM during installation.</P
><P
>If you are going to burn a new EPROM using the binary image,
be careful to get the byte order correct. It needs to be little-endian,
which is usually the default in PC based programmer software.</P
><P
>If the GDB stub EPROM you burn does not work, try reversing
the byte-order, even if you think you have it the right way around.
At least one DOS-based EPROM burner program is known to have the
byte-order upside down.</P
><P
>The GDB stub in the EPROM allows communication with GDB using
the serial port at connector P12 (CMA101) or P3 (CMA102). 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 dedicated serial cable as specified in the
Cogent CMA manual.</P
