In my K64 MCU project, I need to use the cmsis dspi edma driver.
So I ported the code from example "cmsis_dspi_edma_transfer".
But I always got a link error:
.\Objects\hello.axf: Error: L6218E: Undefined symbol Driver_SPI0 (referred from main.o).
.\Objects\hello.axf: Error: L6218E: Undefined symbol Driver_SPI1 (referred from main.o).
I have already included proper header files, and also added fsl_dspi_cmsis.c into project.
But still link error like this.
I am blocked here, any suggestions?
Hi Kevin:
I would suggest you refer to the below demo, it shows how to use DSPI driver in edma way:
SDK_2.4.0_FRDM-K64F\boards\frdmk64f\driver_examples\dspi\edma_b2b_transfer
