S32K311 LPSPI Master Mode not working

Hi,

I tried to communicate with LPSPI, but it doesn't work.

I use RTD and its parameters are set with EB Tresos.
The attached files are the parameters for SPI Driver.

In my source code, I call the functions, Spi_SetupEB() and Spi_AsyncTransmit().
Then the interruption occurs and LPSPI SR register suggests the transmission completes, however, any data is not received nor sent.

In the oscilloscope waves, SIN, SOUT, SCLK, and CS keep low level.

Is there something missing from my setting for RTD?

Could you give me some advice?

Thank you!

Did you config for Pin and Port module for SPI's pins ?
We provided examples for EB Tresos and S32DS for SPI module in installed package already, you can consider it as a reference:

I checked the port settings and realized that the sss setting was incorrect.

Thank you very much!
