The problem is that when I build a project and debug it my target seems to be turned off (No LEDs shining or blinking) and when I exit LPCxpresso, the project I debugged starts to work perfectly (I hear the sound of a USB device connected when I close the software). I tried by clicking on the Run button but it didn't work. "Step by step" option or "Step over" neither. I installed correctly this software (it's activated) and target's driver but I don't know what the root of this issue. Also I reinstalled the expresso, changed workspace's directoty, etc. The programme recognized well my target after i had installed its driver. I also tried all USB ports but the problem persists. It's a pity I can't see in which part of the main code the LPC is because of this.
