S32K1系列是否能通过某个寄存器或通过什么软件手段来判断并确认SPI故障？

我有个需求，需要通过软件的方式来判断并确认SPI物理层已经故障。可以通过什么手段来实现？请帮忙提供可以参考的方案，如果有可运行用于验证的demo code更佳，如果没有请帮忙分析该思路是否可以用贵司芯片实现？#S32K118

Hi @GAC-Lamp-Knight,

The SPI driver does not support hardware errors for the MOSI/MISO lines shorted to BAT, GND or open, but included int he SPI MCAL driver is the following reference:

Which could be used as SPI clock physical error.

SPI_MasterTransferBlocking(&spi1Instance, buf, pOutData, SPI_Frames_Size, TIME_OUT_2MS);我调用得是这个API，启用了DMA；但是不知道通过什么方式可以了解到它是超时没有接收和发送完整得帧数据。

Hi @GAC-Lamp-Knight,

You can use the following community post as reference: Solved: S32K DMA and SPI - NXP Community. There is also this application note: AN12972.
