We set S32K lpspiSrcClk=56000000U, how about the SPI bitsPerSec when work at master mode?
now we could only achieve 7000000U, Thanks. We want to achieve 28000000U.
If you want to use the LPSPI at high clock speed is mandatory to use it in DMA mode.
I will try to come back with a working project, but I think that your clock speed it too high.
The max SPI baud rate is 24MHz in high speed mode as per the datasheet.
