HSM interrupt with SPI

how to enable SPI interrupt at the create time?

Sorry, did not get question. Do you want to know how to enable interrupt mode in SPI? 

Btw, this is not set at the create time. You could select the instance for which you want to enable interrupt, call SPI_socGetInitCfg for this instance, set flag enableIntr in spi_cfg and then call SPI_socSetInitCfg to enable interrupt mode.

Do you mean the  spi_cfg and  SPI_socSetInitCfg in the psdkqa/pdk/packages/src/main_mcspi_slave_mode.c ? Do you have an example there ?

Yes, the example is the file, ti-processor-sdk-rtos-j721e-evm-08_00_00_12\pdk_jacinto_08_00_00_37\packages\ti\drv\spi\example\mcspi_slavemode\src\main_mcspi_slave_mode.c.

Do you mean that I call SPI_socGetInitCfg according to the contents of the SPI_initConfig function（in main_mcspi_slave_mode.c ）, set enableIntr and call SPI_socSetInitCfg, and then I can start the interrupt mode?

or do you mean something else？

Yes, that's correct method. But please note that driver does not take care of programming interrupt routers, that needs to be done by the application. So application can allocate irq number, program it in the interrupt router and then can provide this interrupt number to the driver to be used for mcspi..

For few mcspi instances, interrupt is not directly connected to R5F, it goes via interrupt router, so we need to configure interrupt router..

Where is the application? How does an interrupt router program an interrupt number? How does mcspi use interrupt numbers to achieve functions?

anyupdate？

How to configure interrupt router？I use mcspi0.

Is there any example of receiving data with SPI interrupt？
