I'm getting started with KSDK 2.0 and I'm having some troubling configuring a custom board using Kinetis KL25Z and no external crystal.
I want to run my application with the clock given by the internal oscillator. When I used Processor Expert, I could set it up using FEI mode and set the bus clock to 20.84MHz and the system clock to 41,68MHz.
I see there's a BootToFEIMode() function in fsl_clock.h, but none of the demo apps use this configuration.
How would I have to set up clock_config.h to achieve this?
