Bianca Posted May 31, 2016 Share Posted May 31, 2016 Ok, can you power it through the wall connector? Does the board work? Do you see the power led light? Link to comment Share on other sites More sharing options...
C.Pallavi Posted May 31, 2016 Author Share Posted May 31, 2016 we did it, but it is not working. Where the problem will be ? Link to comment Share on other sites More sharing options...
Bianca Posted May 31, 2016 Share Posted May 31, 2016 Ok just to make sure I understood. -You powered the board using an external 5V power supply through the barrel jack. -You changed the jumper according to the wall supply -you switched the power on the power led is still off -You also tried to power via USB -you put the jumper in USB mode -switched the power on the power led is still off. The conclusion i'm drawing from what are you saying is that in any configuration, with the jumpers correctly placed you cannot see power on the board. Am I correct?

Bianca Posted May 31, 2016 Share Posted May 31, 2016 Then I'm sorry to tell you but, one of your regulators is burned. You managed somehow to make a short on the board or you gave it an over voltage. You can try to debug what could be broken and replace the component but if the FPGA is burned then, your board is dead. Link to comment Share on other sites More sharing options...
