Hi EVERYONE, ACTUALLY , I`M TRING TO TO INTERFACE A SDRAM AND
MICROBLAZE, SO i HAVE SOME PROBLEMS WITH THIS ONE.

I JUST CAN WRITE ONE MEMORY LOCATION ONCE, AND IF i WANT TO WRITE MORE
THAN ONCE THE FPGA AND SDRAM DON`T DO IT.

HERE IS AN EXAMPLE:::::

x = 2;
addr[x] = 7;
i = addr[x];
inve = ~num[i];
XGpio_mSetDataReg(XPAR_LED_7SEGMENT_BASEADDR, 1, inve );

for (j=0;j<1000000;j++) //10000000

XGpio_mSetDataDirection(XPAR_LED_7SEGMENT_BASEADDR , 1, 0x00000000);
;

x = 3;
addr[x] = 4;
i = addr[x];
inve = ~num[i];
XGpio_mSetDataReg(XPAR_LED_7SEGMENT_BASEADDR, 1, inve );

I PRINTED THE RESUL ON A 7 DISPLAY, I JUST SEE THE NUMBER 7, BUT THE
NUMBER 4 I CAN`T SEE.

SO ANY SUGGESTIONS???

THANK IN ADVANCE.

JLUIS
MEXICO.
