SWD error on FRDM K64F


I used win10. At first, it works well to load the program. However, when I want to use the terminal to monitor the output, I downloaded the win10 serial driver for mbed. After installing, I cannot load the program and it provides a fail.txt says "SWD error".

So the problem is that after i installed the serial driver, i could not load the program anymore. I tried to uninstall it, but didn't work.

Also, the red LED turns on periodically, it seems that the board is restarting automatically.

I have tried some kind of holding the reset while loading but it didn't work.

who can help me?

Many thanks.
