SPI Flash Driver for K8x MCUXpresso

[deniscollis]

Is there an existing SPI Flash driver available for Kinetis K8x under MCUXpresso?  Not QSPI (I already have that), but something that layers onto the existing fsl_dspi driver.

Hi Denis Collis，

   We don't have the specific SPI flash driver.

   But we have the DSPI flash driver, so you just need to use the SDK SPI flash driver, then refer to your used external flash, send the related command and data.

  You can download the SDK code for K8X, then refer to the spi project, take K82 SDK as an example:

SDK_2.5.0_FRDM-K82F\boards\frdmk82f\driver_examples\dspi\polling_b2b_transfer\master

Please try it on your side.

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi kerryzhou‌,

Yes, I already explored the various DSPI drivers . I was hoping to save some time with a ready-made flash-specific module to put on top of it.   I guess I'll write my own.

Thanks for responding.

Hi Denis Collis,

   As I know, we don't have the specific external flash driver about the K80, so you need to write it by yourself.

  In fact, it is not complicated!

  When you communicate with external flash, if the SPI_CS wave in the SPI module not meet your external flash demand, you can use the GPIO instead of the SPI module SPI_CS pin.

Wish it helps you!

Have a great day,
Kerry
