Run External Flash

Hello everyone,

I am using the MCXN547-EVK development board and trying to interface an external W25Q64JWTBJQ flash memory using Quad SPI (FlexSPI). I am building the project with IAR Embedded Workbench.

While building the spi_flash example from the MCUXpresso SDK, I encounter the following error:

CMake Error:
Cannot find source file:
.../examples/_boards/mcxn5xxevk/demo_apps/spi/spi_flash/cm33_core0/pin_mux.c

Has anyone encountered this issue before? Could you please help me understand what is causing it and how to resolve it?

Any suggestions would be greatly appreciated. Thank you!

Re: Run External Flash

Hello @Ashish-625

Could you please verify whether the pin_mux.c file exists at the following path?

examples/_boards/mcxn5xxevk/demo_apps/spi/spi_flash/cm33_core0/pin_mux.c

In addition, please confirm which MCUXpresso SDK version you are using and whether the spi_flash demo is download based on IAR Embedded Workbench.

Thank you.

Alice
