I have been working all day with my stm32f4discovery board.

About one hour ago, while debugging, the board stopped responding.

When I plug board into the USB port both LD2 (power) and LD1 (com) turn red and.

If I try to debug a program on the board I get: "Error in Initializing ST-Link device" and "Connection to target failed" in the pop up details.

Re-installing ST-Link didn't work.

I've no idea why this happened.. I was implementing a method with __wfi()  can this break the board? I hope it's not dead because of it :(

Can anyone help?


PS: I am using Atollic TrueSTUDIO for ARM Lite 3.0.0
PPS: I can connect to the board using ST-LINK utility, so maybe it is not dead yet. But no idea how to solve this problem.
