Hi everyone

I was working with stm32f4discovery board.It was working fine and i was able to execute my programs without any difficulties.Now after some day I am working with the same board.But my stm board is not even recognised in the com port of my windows7 pc.I have installed the drivers.As per my knowledge the com port atleast show that driver not found .but it is not even showing that i hav connected any new device.My com port is fine as i have checked with other usb devices.My stm board is getting power as the power led is blinking.But no stm board is getting detected.Please help me

COM port?

What did you change and what where you doing with the board when it stopped working?

Check the voltages on the board.

If you suspect a change in user code the you can pull BOOT0 High and reconnect the board.
