RegVal = Xil_In32(0xFF0A0244) | 0x00000001;
Xil_Out32(0xFF0A0244, RegVal);
/* Set MIO8 output enable */
RegVal = Xil_In32(0xFF0A0248) | 0x00000001;
Xil_Out32(0xFF0A0248, RegVal);
/* Set MIO8 to High /
RegVal = Xil_In32(0xFF0A0044) | 0x00000001; / Changed this from Low to High*/
Xil_Out32(0xFF0A0044, RegVal);
(void)usleep(5);
