Hi
First of all, thank you for the patience.
There is a document <Kinetis Bootloader QuadSPI User's Guide.pdf> chapter 7 provide more detailed info about how to change the MCG clock mode from FEE to PEE. You also could find related demo project at KBOOT V2.0 installation path.
I attached the <Kinetis Bootloader QuadSPI User's Guide.pdf> file for your reference.
I would recommend customer to download the KBOOT v2.0 software to get the demo code.
Wish it helps.
Have a great day,
Ma Hui
