Hello,
I am trying to set up a simple routine for the S32K148 EVB to act as a SPI-Slave. My issue is with the functions from the Lpspi_Ip. Following version is used:
* Project : RTD AUTOSAR 4.4
* Platform : CORTEXM
* Peripheral : LPSPI
* Dependencies :
*
* Autosar Version : 4.4.0
* Autosar Revision : ASR_REL_4_4_REV_0000
* Autosar Conf.Variant :
* SW Version : 1.0.0
* Build Version : S32K1_RTD_1_0_0_D2108_ASR_REL_4_4_REV_0000_20210810
I have tried implementing following functions:
/* Initalized clock */
Clock_Ip_Init(&Mcu_aClockConfigPB[0]);
/* Initialize interrupt */
IntCtrl_Ip_Init(&IntCtrlConfig_0);
IntCtrl_Ip_ConfigIrqRouting(&intRouteConfig);
/* Initalized spi using instance lpspi as a spi slave */
Lpspi_Ip_Init(&Lpspi_Ip_PhyUnitConfig_SpiPhyUnit_0_BOARD_InitPeripherals);
/* Update Transfer Mode */
Lpspi_Ip_UpdateTransferMode(SLAVE_EXTERNAL_DEVICE.Instance, LPSPI_IP_INTERRUPT);
/* Slave set up and waiting active signal of Cs from master to process data reception */
Lpspi_Ip_AsyncTransmitHalfDuplex(&SLAVE_EXTERNAL_DEVICE, RxSlaveBuffer, (uint16)NUMBER_OF_BYTES, LPSPI_IP_HALF_DUPLEX_RECEIVE, SpiCallBack);
I use an external device to send SPI-frames to the board. --> If I send something, the Lpspi_Ip_GetStatus(SLAVE_EXTERNAL_DEVICE.Instance); status stays BUSY. I am realy not sure how to aproach this properly.
Can you help me out somehow?
Thanks in advance for your support!

Hello @namnguyenviet,
I urgently need assistance. Your colleague @cuongnguyenphu does not seem to answer to my request. It is quite important, that we solve this issue, due to a deadline of our customerproject.

Hello @namnguyenviet,
thank you for your quick reply. And also a happy new year!
The interrupt handle is called without issues using following function: Lpspi_Ip_IrqHandler(SLAVE_EXTERNAL_DEVICE.Instance);
Also I have added some void testFunction in the "generic interrupt settings" (LPSPI0_IRQn)
This function is also never called if my external device sends dome SPI commands.
Best Regards,
Kim
