@nuc_five This is important when using EMIO pins for SPI.
When using EMIO pins, tie SSIN High in the PL bitstream. Ensure that the PS–PL voltage level shifters are enabled, and that the PL is powered and configured. Otherwise the SPI controller will not function properly.
Make sure in your bd you tie SPI0_SS_I pin to constant one.
