0098 Board description
0099 -----------------
0100 Clock rate: 40MHz (board can run up 66MHz with alternate OSC)
0101 Bus width: 32 bit Flash, 64 bit SDRAM
0102 FLASH: 8M SIMM
0103 RAM: 16M SDRAM DIMM
0104
0105 The board is marked with "Rev PILOT"
0106 U17 is marked with "MPC8260ADS Pilot 00"
0107 The processor is marked with "XPC8260ZU166 166/133/66 MHz"
0108
0109
0110 Board Configuration:
0111 --------------------
0112 The evaluation board has a number of configurable options:
0113
0114 DIP switch settings used:
0115 DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off"
0116 DS2: all "on"
0117 DS3: all "on"
0118
0119 A 40MHz oscillator is fitted to U16.
0120
0121
0122 Board Connections:
0123 ------------------
0124 Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to
0125 get console I/O. A 9way male-female straight-through cable is required to
0126 connect to a PC.
0127
0128 If you require the network connections (see README in network directory)
0129 you need to connect 3VTTL - RS422 level convertors to the CPM expansion
0130 connector, P4. The signals, as numbered on the connector itself
0131 (beware: the numbering on the PCB does not agree):
0132
0133 TX Data (SCC3 TXD) (output) Pin a25
0134 TX Clock (BRG4O) (output) Pin a11
0135 Rx Data (SCC3 RXD) (input) Pin c15
0136 Rx Clock (CLK5) (input) Pin d28
0137 Ground (GND) (n/a) Pin c1
0138
0139
0140 Debugging/ Code loading:
0141 ------------------------
0142 Tested using the Metrowerks debugger and Macraigor OCDemon (Raven).
0143 The OCD connects via the parallel port and allows you to download code
0144 to the board. It may be possible to use some other debugger if you
0145 don't already have Metrowerks CodeWarrior.
