i want to do memory(FPGA) data transfer via EBIU in AMC mode. For that i have configured AMC register

void EBIU_AMC_Init_Read()
    *pEBIU_AMGCTL=AMBEN_ALL|AMCKEN;    //CDPRIO, DMA has priority over core for for external accesses }


After that i want to read data from memory for that


Void EBIU_DATA_Read()

short *iSrcBufferAddress = (short*)0x20300000;//Async Memory BANK3

int j;
for(j=0; j< 100 ; j++)
destbuff1[j] = iSrcBufferAddress++;


But neither data nor control signal (ARE,AOE etc)was present .

whats wrong in the code?
