Hello, for a few days I am dealing with DRV8711 (it doesn't work). The schematic and the layout are made by myself. Can someone take a look on these?

Does the motor do anything at all?
What level do you set on the sleep and reset pins?
Can you read and write to the control registers?

Where is the connection from DRV8711, pin5, to GND? You may have labelled the net as GND, but you don't show that. Someone viewing the schematic has no idea whether that connection exists or not.
