Hello. support team.


I use s32k118 & 3.0 SDK.


Now I have a problem that spi read operation in slave mode.

Slave sends well data to the master. but Slave can not receive data from the master.


uint8_t slaveDataSend = 0x14;

uint8_t slaveDataReceive = 0x0;


LPSPI_DRV_SlaveTransfer(DRV_SPI_SLAVE, &slaveDataSend, &slaveDataReceive, 1);


slaveDataSend --> Master receive well slave write data.

slaveDataReceive -->  Slave can not receive Spi Read data from the master.


Could you please let me know how to receive spi data in slave mode?


Could you send me a sample code about spi read operation in slave mode?
