Within the MCUXpresso SDK, the non-RTOS initialization drivers for LPSPI include "LPSPI_MasterInit" and "LPSPI_SlaveInit". When FreeRTOS is included, the associated RTOS driver is "LPSPI_RTOS_Init" which I initially presumed would have parameters for master or slave, but that doesn't appear to be the case. Within LPSPI_RTOS_Init, LPSPI_MasterInit is called, but LPSPI_SlaveInit is not. In fact, in the file "fsl_lpspi_freertos.c" there is no reference to the word "slave" at all!
When looking at the LPSPI / FreeRTOS example code (not available in the SDK for the RT1060 and RT1064), the FreeRTOS slave task initializes directly with "LPSPI_SlaveInit".
Why is their only a master LPSPI initialization function for FreeRTOS?
