Board description
|
|
-----------------
|
|
|
|
Clock rate: 40MHz (board can run up 66MHz with alternate OSC)
|
|
Bus width: 32 bit Flash, 64 bit SDRAM
|
|
FLASH: 8M SIMM
|
|
RAM: 16M SDRAM DIMM
|
|
|
|
The board is marked with "Rev PILOT"
|
|
U17 is marked with "MPC8260ADS Pilot 00"
|
|
The processor is marked with "XPC8260ZU166 166/133/66 MHz"
|
|
|
|
|
|
Board Configuration:
|
|
--------------------
|
|
|
|
The evaluation board has a number of configurable options:
|
|
|
|
DIP switch settings used:
|
|
DS1: 1-"off", 2-"on", 3-"off", 4-"on", 5-"off", 6-"off", 7-"off", 8-"off"
|
|
DS2: all "on"
|
|
DS3: all "on"
|
|
|
|
A 40MHz oscillator is fitted to U16.
|
|
|
|
|
|
Board Connections:
|
|
------------------
|
|
|
|
Connect a serial terminal to PA3 (SCC2) configured for 9600,n,8,1 to
|
|
get console I/O. A 9way male-female straight-through cable is required to
|
|
connect to a PC.
|
|
|
|
If you require the network connections (see README in network directory)
|
|
you need to connect 3VTTL - RS422 level convertors to the CPM expansion
|
|
connector, P4. The signals, as numbered on the connector itself
|
|
(beware: the numbering on the PCB does not agree):
|
|
|
|
TX Data (SCC3 TXD) (output) Pin a25
|
|
TX Clock (BRG4O) (output) Pin a11
|
|
Rx Data (SCC3 RXD) (input) Pin c15
|
|
Rx Clock (CLK5) (input) Pin d28
|
|
Ground (GND) (n/a) Pin c1
|
|
|
|
|
|
Debugging/ Code loading:
|
|
------------------------
|
|
|
|
Tested using the Metrowerks debugger and Macraigor OCDemon (Raven).
|
|
The OCD connects via the parallel port and allows you to download code
|
|
to the board. It may be possible to use some other debugger if you
|
|
don't already have Metrowerks CodeWarrior.
|
|
|
|
|
|
|
|
