AM335x: How to trigger a GPMC DMA event?

yang yang2

On Table11-23 in AM335X TRM GPMCEVT is an event for EDMA. But how can we trigger this event? I searched the relevant part but only got nothing useful. Anyone can give some hints?

Best Regards

Hi, Biser

It seems #100 interupt is used as GPMCEVT, am I right? But in which condition the GPMCINT will happen?

INT 100 is an interrupt from the GPMC, not a DMA event.
