I am working on the SD card portion of a project and when I build the project using Kinetis 3.1.0 and Kinetis SDK 1.3.0; I am getting the error: fatal error: fsl_dspi_master_driver.h: No such file or directory. It seems to me that the file, "fsl_dspi_master_driver.h", can't be located. I would like to know how I can locate the location of this file / add it to the project. I am new to Kinetis and slowly learning my way around. I am also getting warnings for the following includes as well: "fsl_dspi_edma_master_driver.h" and "fsl_sdcard_spi.h". Any assistance would be appreciated. Thank you.
