Hello. I am trying to flash the FRDM-K64F using the inbuilt debugger OpenSDA. But I'm getting an error which I have attached in the screenshot. Actually a lot of errors appear quickly on the console and disappear before I can take a screenshot. I'll try to post those also

The steps I have taken are as follows-
1.Installed mbed driver from the website, with the device plugged in as mentioned in its instructions.
2.Installed OpenSDA drivers from PEMicro website, again with device plugged in and all windows explorer windows closed as mentioned in its instructions.
3.Configured Debug Profile as per KDS 2.0.0 User Guide to use PEMicro's OpenSDA debugger.
What could be the problem?
