I'm the first time using freescale's board.how to solve this problem?thanks.
We would need some more detail to address this.
However, one condition that can lead to this error is not powering up the board that the USB TAP or other debug device is connected to.
The board must be powered up prior to attaching any debug pods. An unpowered devcice is much more subject to damage due to external voltages.
The problem "fixed" after retart the PC.Thanks anyway and I will keep in mind what you say!
