I am getting some warnings for errors which don't exist.

For example in this function it warns me that iLed is an unused variable :!: Yet it is clearly assigned in the initialisation of the 'for' loop and accessed in the body.

Will the following method work to access 128k of byte wide SDRAM using the MOD5270 module ?

The problem being I only have the address lines A0-A15 coming out of the module and the SDRAM has A0-A16. However could I use two chip selects and a bit of LV logic to create an A16 signal for my SDRAM chip ...

Figured it out !

I don't need this bit that setups CS3
// setup CS3 for I/O access
sim.cs[3].csar = (IO_BASEADDRESS >> 16 );
sim.cs[3].cscr = 0x2140; /* 0010 0001 0110 0000 */
sim.cs[3].csmr = 0x001F0001;

It seems this CS3 would clash with accesses to the CS1 area.

I finaly got some time to return to my project and but I am having a problem with exceptions.

I have taken the code advice form above and implement a simple class to access the external bus. I am trying to use d0-d15 as digital I/O whilst also accessing some 64k of byte wide SRAM using d24-d31. I ...

Yes the design uses 130 circuit boards each with 32 RGB Leds each. The LED circuit boards all "tile" together to create a panel the size of a wide door. Each circuit board uses the two MAX6974 driver chips for multiplex control of 32 RGB leds. The 130 LED boards cacade the LVDS data single down the ...

What happens with these TA, TIP and TS signals ? Will my read/write external bus acceses hang if I leave them unconnected ? Is there some 'C' lib function that will setup the external bus config ?

I note that the address/data bus is only specified with enough umph to drive one load, so does it ...

The LED drivers I am using require a clocked data stream at about 30Mhz and since I have 4,160 RGB leds which need which each need 36 bits of intesity data at 50 frames per second the CPLD is pretty busy nocking out 7.488 Mbps 8-) .

So that this data rate demand does not fall on the shoulders of ...

I have just done the "Getting started guide to NB Eclipse" and got my dev kit running demos (Trying NB for the first time having used Rabbit & PIC's on previous projects). I need to prototype hooking the MOD5270 upto a CY7C009V dual port ram (128k x 8bit).

From my cursory review of various doc's ...
