V3.2 Board not on

My evaluation board is not on
When I give a supply LED 13,and reset out Leds on and off immediately kindly help me what is the problem

Sounds like there is short somewhere? Did the board ever worked before?

It was working suddenly problem occured in running condition
and also checked iwith out I/O connection Only with power supply

It was worked very well but suddenly problem happened

This sounds like an RMA case. If your device is still under warranty you can open an RMA case, so we can further analyse the situation. You find the RMA form here.
