I am trying to connect two evaluation boards, FRDM-K66F and TWR-KV58+elevation, using the SPI interface. Trying to use the FreeRTOS example for DSPI. When i connect two FRDM-K66F boards using SPI0 on both and the freertos example, i see the data going through correctly. But when i connect the FRDM-K66F that was the slave to a TWR-KV58 (with elevation boards) to serve as the master, i don not get any indication of incoming data on the K66F side.
This is how i connected the pins:
MOSI B45 MISO J2 pin 8
MISO B44 MOSI J2 pin 10
SCK B48 SCK J2 pin 12
PCS0 B46 PCS0 J2 pin 6
GND B2 GND J2 pin 14
The code is unmodified freertos_dspi example, with EXAMPLE_CONNECT_DSPI set to BOARD_TO_BOARD.
Master is built with SPI_MASTER_SLAVE isMASTER and slave is built with SPI_MASTER_SLAVE isSLAVE.
Both using SPI0
Do i need to change any configurations to make this setup work?
