Hi Guys,
I just got a EVKB board and have had great troubles getting a new project to run on the board. After a few hours of swearing, trying different debug probes, trying different PCs and general gnashing of teeth I think I have tracked down the issue.
Something is bad in the default clock_config.c. This is easy to replicate just create a new project, default everything then debug it. It never returns from BOARD_BootClockRun() and the board is also now toast the debugger will not connect to it again, the only way to get it back is to erase the flash and start again:

I have tried this with a machine that has never had MCUXpresso installed before with the new EVKB sdk and get exactly the same problem so I am guessing it is nothing to do with having the EVKA sdk installed previously.
If I use the clock_config.* from the led_gpio example, overwriting the generated one in the new project then everything works fine.
Cheers
Andy
