Hi all,

 

We are having some problem getting the K21 works with High gain Oscillator operating mode using Processor Expert. The code keeps hanging in cpu.c (see photo below)

The K21 works ok with Low power mode. The reference manual says that this option should work.

Here is my external crystal setting in Processor expert:

Here is where the code is stuck at:

Any help is appreciated.
