FlexSPI on RT1170

[LoicBe]

Hello,

I'm using a RT1170 EVK board and I wanted to use FlexSPI FSL driver.

I can use without any problem the FlexSPI SDK example in MCUXpresso.  But, when I try to implement it in any other application, calling FLEXSPI_Init() makes the application crash immediately.

As a first step to understand it, I tried to implement some FlexSPI manipulation from a working SDK ("flexspi nor polling transfer") in another simple "Hello World" SDK example. 

So I added the flexspi driver from the "Manage SDK Component" GUI, I added the pins configuration in "pin_mux.c", the "flexspi_nor_flash_ops.c" and the related code from one example to another.

I checked the memory configuration to make them quite identical, but still, even the simple init call to "flexspi_nor_flash_init(EXAMPLE_FLEXSPI);" makes the modified "Hello world" app crash...

I do not really know where to look now... Any help would be very appreciated.

Best regards,

Loïc.

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I think the root cause is forgetting to relocate the FlexSPI driver to the RAM prior to calling them.
Have a great day,

Hi @jeremyzhou,

Thank you for your answer, you are right.  I did not pay attention to the "linkerscripts" folder in the FlexSPI SDK example that allows to relocate the driver into the RAM.

It is working now!

Best regards,

Loïc.
