README 

The supported features of the SBC8240/8245 board are:
    8240 or 8245 processor
    66MHz & 100MHz bus speed
    Decrementer timer
    1 UART channel (Console channel)
    8240 Interrupt Controller
    8240 PCI bridge
    8240 Memory Controller
    SDRAM (16, 64 MB Memory DIMM)
    FLASH 512K On board
    FLASH 4MB On board


Memory Map from CPU point of view:

    Start	 Size	Access to
    -----------------------------------------------------
    0x00000000	 64MB	SDRAM DIMM
    0xFF000000	  4MB	On Board FLASH
    0xFFF00000	512K	On Board FLASH or SRAM (Configured by jumper)
    0xFFE00000	  8K	EEPROM
    0xFFE80000	  8Bit	LED
    0xFFF80000	  8Bit	UART


Setting the board Jumpers & Switches:

   In order to get the board running with the default configuration the
   jumpers need to be set as follows:

  General Jumpers:
    ____________________________________________
   |   Jumpers	 |   Jumpers	|    Jumpers	|
   |-------------|--------------|---------------|
   |JP1	    1-2	 | JP14	   1-2	| JP27	  1-2	|
   |JP5	    Open | JP15	   1-2	| JP28	  2-3	|
   |JP8	    1-2	 | JP16	   1-2	| JP33	  Open	|
   |JP9	    1-2	 | JP17	   1-2	| JP37	  Close |
   |JP10    1-2	 | JP18	   1-2	|		|
   |JP11    2-3	 | JP19	   1-2	|		|
   |JP12    1-2	 | JP20	   1-2	|		|
   |JP13    1-2	 | JP25	   Open |		|
   |_____________|______________|_______________|

  Bus speed Jumpers:
