My fpga(zybo 20) is not working.

It is said that the LED of 'LD13' lights up when the micro 5pin is connected to the fpga and pc and switched on. But my led doesn't glow. How can I solve this?

 

+When connecting the device, the connection tone sounds several times, but the connection is not actually connected and is disconnected.

HI @dooeun,

Have you gotten to try a different cable (or less likely from a troubleshooting perspective, use an external power supply rather than having the power supplied through the USB cable) to help rule out that particular point of failure? Based on your picture, your general hardware setup looks correct.

When you say the connection is not actually connected, do you mean that you are not able to successfully see the device in the Windows Device Manager (presuming you are using a Windows OS?)

Thanks,
JColvin
