Hello Vane,
I'm not using any example as I couldn't find any for this micro. I can share with you my test program:

Where I basically toggle one GPIO (PTE9).
The point here is that when I attach the debugger and run the program, it works correctly. The problem is when I try to run it without the debugger.
I also couldn't find any example that uses the external oscillator.
