Why the function:CLOCK_SetFroOutClkSrc(kCLOCK_FroSrcFroOsc); /*!< Set FRO clock source */somethimes ended up in a Hard Fault? It works perfectly in 50% of cases.
Hello @senge-esca
For better help you, please describe your question more detail?
How to reproduce your issue?
What about your project?
When hard fault?
