+Time to test the software! Bring up your favorite Xilinx Zybo SoC board, and ensure that jumper 5 (JP5) is configured for booting via JTAG. Connect the board to the computer, and power it up. Then in Xilinx SDK, goto ''Xilinx --> Program FPGA''. If successful, goto ''Run --> Run as --> 1 Launch on Hardware (System Debugger)''. The 4 LEDs on the board should now light up and blink.
