>The eCos Developer&#8217;s Kit package comes with an EPROM
88
which provides GDB support for the Motorola
89
PowerPC MBX860 evaluation board. An image of this EPROM is also
90
provided at <TT
91
CLASS="FILENAME"
92
>loaders/powerpc-mbx/gdbload.bin</TT
93
> under
94
the root of your eCos installation.</P
95
><P
96
>The EPROM is installed to socket XU1 on the board. Attention
97
should be paid to the correct orientation of the EPROM during installation.
98
Only replace the board&quot;s existing ROM using a proper PLCC
99
extraction tool, as the socket would otherwise risk getting damaged.</P
100
><P
101
>The GDB stub in the EPROM allows communication with GDB using
102
the serial port at connector SMC1/COM1. The communication
103
parameters are fixed at 38400 baud, 8 data bits, no parity bit and
104
1 stop bit (8-N-1). No flow control is employed. Connection to the
105
host computer should be made using a suitable serial cable.</P
106
><P
107
>In order to make the board execute the EPROM that you just
108
installed (rather than the on-board FLASH memory), it may be necessary
109
move some links on the board. Specifically, ensure that link J4
110
is in position 1-2. If in doubt, refer to the MBX documentation
111
from Motorola, ensuring that Boot Port Size=8 Bits/ROM
112
for BOOT (CS#7), in their terminology.</P
