evaluation board. An image of this EPROM is also provided at

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

>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.

the byte-order, even if you think you have it the right way around.

>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
