i am powering the board through usb (J28). mcu is not booting. i can feel the U31 hot and it keep getting hotter. LED D16 glows for some time and go off. 

 

how can i debug this? if remove the jumper J1 connection, the heat goes away. so i believe, the circuit after the J1 trying to take more current. 

 

what component can go bad?

 

Thanks

Vinay
