Hi Raja,
    Did you update the xparameters_ml300.h or xparameters_ml403.h file 
with the right defines for your specific board? If not, then you need to 
update the file first. This first is automatically generated by the EDK 
toolset. However, you might also choose to do it manually if you know 
the right values. The driver would work with the right base-address.

cheers,
-Ameet

 Hi all,

   I got the system Ace driver compiled in to linux
2.6.12 but once the board boot's up , the console
shows
 
   Data machine check in kernel mode.
and continously runs the call trace.

when  i debugged the this problem on xsyace driver
codebase the it hangs  at function in & calls call
trace
 
      >adapter.c 
 
 -->   if (XSysAce_Initialize(&SysAce, cfg->DeviceId)
!= XST_SUCCESS)

when further debugged the function XSysAce_Initialize
it call the funtion XSysAce_RegWrite16
       
         >xsyace.c

  -->#if (XPAR_XSYSACE_MEM_WIDTH == 16)
    XSysAce_RegWrite16(InstancePtr->BaseAddress +
XSA_BMR_OFFSET,XSA_BMR_16BIT_MASK);

in further debugging on the function
XSysAce_RegWrite16
shows
       >xsysace_l.c

 --> #if (XPAR_XSYSACE_MEM_WIDTH == 16)
void XSysAce_RegWrite16(u32 Address, u16 Data)
{
    u16 ConvertedData;
                                                      
                                                      
               
    /*
     * The ACE registers are little-endian always.
This code takes the incoming
     * 16-bit and endian converts it, then writes it
to the ACE register.
     */
    XIo_ToLittleEndian16(Data, &ConvertedData);
    XIo_Out(Address, ConvertedData); /***** the
execution 
runs the call trace from this point ******/

}



I beleive their problem with  macro value in
               > xparameters.h

   XPAR_SYSACE_COMPACTFLASH_BASEADDR 0x41800000
 can some one please explain how to specify the 
value for this macro mine is xccace-tq144i System ace
or else is their any other problem to solve.please
help me in this.thanks in advance.
