The BSPI support does work in master (just verified with 7I65) I'm not sure there are any HAL accessible BSPI pins here are the applicable INI and HAL file bits of a 7I65 config INI: [HOSTMOT2] DRIVER=hm2_pci BOARD=5i24 CONFIG="num_encoders=8 num_bspis=1" HAL: # load low-level driver loadrt [HOSTMOT2](DRIVER) config=[HOSTMOT2](CONFIG) loadrt mesa_7i65 bspi_chans=hm2_5i24.0.bspi.0 > > Sorry to infect one thread with another :-).
