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!
