When I try to run any of the LPSPI examples on IMX8ULP (ex. lpspi_edma_b2b_transfer_master.c) the data doesn't seem to be read or outputted. On the oscilliscope, I can see that chip select is switching, and sck is switching, but sout doesn't have any data. Setting Sin Low/High Doesn't change recerived data either. Please Help!

Which version of SDK are you using?

Which board are you using?

How you connect the two spi?

Is there any error message?
