Hi jze duan,

   Do you want to put all the code to the QSPI and run from qspi, or just want to put some part of the code to the qspi flash, and still run from the internal flash?

  If you want to run from the qspi, you can refer to this document:

https://www.nxp.com/docs/en/user-guide/MBOOTQSPIUG.pdf 

  If you just want to copy part of the code to the QSPI, you can refer to my attached code.

Wish it helps you!

If you still have question about it, please kindly let me know.
Have a great day,
kerry

Hi Kerry Zhou,

Use your development board frdm-kl82z for debugging. According to the operations (MCU Bootloader QuadSPI User's Guide.pdf)in chapter 3 on the PDF file you provided, the prompt is as shown as the error.

Hi Duan jz,

     configure-memory address is wrong, you are using 0X02000000, BUT you need to use 0X20000000

Please try it again.


Have a great day,
Kerry
