Slow down access to quad SPI flash

I have a proto board with mismatched trace lengths between the processor and SPI flash memory, which is causing timing problems.  Is it possible to slow down the SPI interface in mcuxpresso to a speed to allow programming and access?

Hi,

Yes, customer can slow down the SPI Flash serial clock.

Just using SDK provided demo <flexspi_hyper_flash_polling_transfer>, the <app.h> has below function to initialise FlexSPI clock:

static inline void flexspi_clock_init(void)

Thanks for the attention.

Mike
