->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
- <TT
-CLASS="FILENAME"
->loaders/powerpc-cogent/gdbload.bin</TT
-> under
-the root of your eCos installation. The same EPROM and image can
-be used on all three supported daughterboards: CMA287-23 (MPC823),
-CMA287-50 (MPC850), and CMA286-60 (MPC860).</P
-><P
->The EPROM is installed to socket U4 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 big-endian.
-If the EPROM burner software has a hex-editor, check that the first
-few bytes of the image look like: </P

->If the byte order is wrong you will see 603c instead of 3c60
-etc. Use the EPROM burner software to make a byte-swap before you
-burn to image to the EPROM. </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
