SPI S32K344 Baudrate issue

vinaykl — Wed, 15 Oct 2025 05:43:47 GMT

Hello Team,

I am trying to configure max SPI Baudrate to 20mHz. As mentioned in user guide of S32K3xx SPI, its clearly mentioned LPSPI0 baudrate can be changed up to 20mHz. But I am not able to change it more than 15000000 in peripheral library. Adding the screenshot with this query.

Kindly let me know how to make it possible. Or let me know the limitations.

Thanks, and regards

Vinay

Please check the clock settings in the Clocks Tool, for example, what is the frequency of AIPS_PLAT_CLK?

Best Regards,
Robin
