91 | Board description |
---|
92 | ----------------- |
---|
93 | |
---|
94 | Clock rate: 40MHz (board can run up 66MHz with alternate OSC) |
---|
95 | Bus width: 32 bit Flash, 64 bit SDRAM |
---|
96 | FLASH: 8M SIMM |
---|
97 | RAM: 16M SDRAM DIMM |
---|
98 | |
---|
99 | The board is marked with "Rev PILOT" |
---|
100 | U17 is marked with "MPC8260ADS Pilot 00" |
---|
101 | The processor is marked with "XPC8260ZU166 166/133/66 MHz" |
---|
102 | |
---|
103 | |
---|
104 | Board Configuration: |
---|
105 | -------------------- |
---|
106 | |
---|
107 | The evaluation board has a number of configurable options: |
---|
108 | |
---|
109 | DIP switch settings used: |
---|
110 | DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off" |
---|
111 | DS2: all "on" |
---|
112 | DS3: all "on" |
---|
113 | |
---|
114 | A 40MHz oscillator is fitted to U16. |
---|
115 | |
---|
116 | |
---|
117 | Board Connections: |
---|
118 | ------------------ |
---|
119 | |
---|
120 | Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to |
---|
121 | get console I/O. A 9way male-female straight-through cable is required to |
---|
122 | connect to a PC. |
---|
123 | |
---|
124 | If you require the network connections (see README in network directory) |
---|
125 | you need to connect 3VTTL - RS422 level convertors to the CPM expansion |
---|
126 | connector, P4. The signals, as numbered on the connector itself |
---|
127 | (beware: the numbering on the PCB does not agree): |
---|
128 | |
---|
129 | TX Data (SCC3 TXD) (output) Pin a25 |
---|
130 | TX Clock (BRG4O) (output) Pin a11 |
---|
131 | Rx Data (SCC3 RXD) (input) Pin c15 |
---|
132 | Rx Clock (CLK5) (input) Pin d28 |
---|
133 | Ground (GND) (n/a) Pin c1 |
---|
134 | |
---|
135 | |
---|
136 | Debugging/ Code loading: |
---|
137 | ------------------------ |
---|
138 | |
---|
139 | Tested using the Metrowerks debugger and Macraigor OCDemon (Raven). |
---|
140 | The OCD connects via the parallel port and allows you to download code |
---|
141 | to the board. It may be possible to use some other debugger if you |
---|
142 | don't already have Metrowerks CodeWarrior. |
---|
