Hello Tom,
These steps depend on MCU and project you want to create. If you want to use Processor Expert Init and LDD components (without SDK) you can use DMAChannel_LDD and Init_SPI components (SPIMaster_LDD component does not support eDMA). You must set one DMAChannel for SPI receive request and one DMAChannel for SPI transmit request for the selected SPI device. The Init_DSPI must be initialized for using DMA. But you must implement all DSPI functions by yourself.
If you create a Processor Expert with Kineits SDK 1.1, you can use fsl_dspi component, set the requested DSPI mode (e.g. Master) and use DSPI_DRV_Edma... methods to use DSPI with eDMA.
