No SPI data transfer on NXP s32k344 q172 while S32K344 EVB acting as slave

Hi,

I am using MBDT toolbox and configuring LPSPI1 as slave channel and other 3 party controller SPI as master. I am not observing any MOSI data. I checked with Logic analyzer as well as free master. There is no MOSI data observed. Please let me know if there is anything I am configuring wrong or SPI as slave doesnt work with other controllers.

The Model file is as shown below.

Please find the logic analyzer signals observed. I have used PCS3. The CPOL and CPHA on the other controller is high and CSpolarity is low.

Please suggest me if I am doing anything wrong. Also where can I find the callback functions used in configuration.

Rajesh
