My Edison board can't startup and can't reflash now. I'm using it running my application this morning, and after some minutes the target hanged (no response and output from the terminal). I have to plug the USB cable to the power adapter and reboot it again, but it hanged when showing "Starting kernel ... " for a long time ( about one hour ). I tried to use flashall.sh to reflash it, I plug the USB cable to PC according to the notification, but it seems that the target can't be detected by the PC with USB cable. What's the matter with it? Does the USB port damaged?
When I use a power adapter to power up, it shows folloing messages but hangs in "Starting kernel..." as followings. And when I connect USB cable with PC, it shows nothing.

When I use flashall.sh to reflash it, it's shows following messages. I know the steps of flashing the target. I've flashed it before, but it fails now.
