I've just started using the FRDM-K64F board and encountered several issues:
1- When for the first time the board is connected to the USB port of my PC, the pre-loaded (Bubble) app does not work as expected.
2- With the board powered by the USB port, my PC opens a directory MBED (E:\) with several empty files.
3- With all software installed, I tried to program the board using SDK examples, at the end of programming (Debug), I get a connection error. Attached is the debug log console.
Below was also copied from the Console window:

I appreciate any help.
Thanks!
The console logs I'd like to see can be copied from the MCUXpresso IDE console tab. One console is for gdb-traces. The other is the debug log. See The Debug Log. Please copy these and paste as a response, or, add as an attachment.
Thanks and regards,

EDIT: If you're a Windows 10 user, there have been reports of the OpenSDA v2.1 becoming corrupted. See OpenSDA Serial and Debug Adapter|NXP.
You don’t have a viable debug connection. Please post the entire debug console log which captures the output from the script execution. You may need to use the mass erase script.
Thanks and regards,

The entire debug console log is attached. I also noticed that the board works fine with PCs running on Window 7. Only PCs with Windows 10 have these issues.
Thanks!
Thanks, we'll let you know what we find.
