I am using SPI2 to communicate with a NOR FLASH S25FL164K. I am using MK22FN1M0AVLL12. I got it the example of DSPI of the tower K21 on MCUXpresso on the SDK examples. I tryed to communicate but the SCK don´t oscilate, I configured the pins and the SPI2 in the code of example. When I init the SPI the SCK not oscilate even I executing Write Data. Anybody can help me?
