Hi ZEROooo,
Unfortunately, We don't have a demo or some configuration data available. To configure SPI on EB Tresos, you can refer to the "AUTOSAR_MCAL_SPI_UM.pdf" and "AUTOSAR_MCAL_SPI_IM.pdf" files in the SPI module folder and follow the "Spi Specification Autosar" to deploy code at the HLD layer.
Best regards,
Dan
