s32ds spi intterupt request

rlaxortn — Mon, 16 Mar 2026 01:28:43 GMT

hello.

i am using s32k314 mcu, and s32ds 3.6.1 version. RTD is 4.0.0

and i don't use mcal, and autosar. i only can use low drivers.

1. To use SPI interrupts, do I need to add Dma_Ip to the drivers in S32DS Peripherals? Can I use it by adding only Intctrl_Ip without Dma_Ip?

2. if i can use spi interrupt without Dma_Ip, how i can find callback function? and how i set callback function name?

thanks.

I checked the non-AUTOSAR MCAL version of Lpspi, and it seems the S32 Configuration Tool does not support configuring callback of LPSPI.

I suggest referring to the following sections in RTD_SPI_UM.pdf:
6.4.4.1 Lpspi_Ip_CallbackType
6.4.5.1 Lpspi_Ip_EventType
6.4.6.4 Lpspi_Ip_AsyncTransmit

The Handler's name needs to be filled in IntCtrl_Ip, for example, Lpspi_Ip_LPSPI_0_IRQHandler. The name can be found in /RTD/src/Lpspi_Ip_Irq.c.

The name of the LPSPI callback is mentioned in "6.3 Calls to Notification Functions, Callbacks, Callouts" of RTD_SPI_IM.pdf:

RTD_SPI_UM.pdf and RTD_SPI_IM.pdf are located at: C:\NXP\S32DS.3.5\S32DS\software\PlatformSDK_S32K3\RTD\Spi_TS_T40D34M40I0R0\doc\

Best Regards,
Robin
