hello yager.project,
please refer to Sensor Software Driver Programming Guide to implement your driver.
you should start with Port Binding, to have node definitions of the port binding for VI, NvCSI, and also sensor modules. it’ll register video node, (i.e. /dev/video0) if you have correct assignment.
for the next step, you’ll need to complete device tree (*.dtsi) property definition, for example, clock, GPIO, and regulator properties definitions.
BTW,
you may also refer to Topic 83289, multi-brick streams (i.e. gang mode) is NOT implemented for Xavier’s VI drivers.
thanks
