Hi,
I'm trying to use the either normal run mode or HS run mode in my QSPI program. I've tried using the two provided functions:
BOARD_BootClockRUN and BOARD_BootClockHSRUN
My program seems to never get past these function calls when I use them in a QSPI program. If I use these functions in a program running from flash they work as expected.
Any tips on increasing the core clock speed in a QSPI program?
Thanks.
Hi
If you are using KSDK V2.0 QSPI example demo?
Wish it helps.
Have a great day,

Yes I am using the hello_world_qspi example from KSDK_2.0 for the FRDM-K82F. Out of the box the program flashes and runs correctly from QSPI but if I add "BOARD_BootClockRUN();" immediately after "BOARD_InitPins();" then the program no longer works correctly and faults without printing "hello world".
Did you find a solution to this?
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

Hi
Sorry for the later reply.
I re-generate the same issue with [hello_world_qspi] demo.
I was checking this issue with KSDK software team.
I will let you know when there with any feedback.
Thank you for the patience.
