hello rary,
here are some details about the port-index of NVCSI and VI
nvcsi@ node should be the NVCSI port
CSI Port A := 0
CSI Port B := 1
CSI Port C := 2
CSI Port D := 3
CSI Port E := 4
CSI Port F := 5
CSI Port G := 6
CSI Port H := 7
vi@ node should be NVCSI PixelParser index (aka. stream_id), the last two bricks, each CSI-E/F and CSI-G/H share a single PixelParser.
Stream 0 := 0 (CSI Port A)
Stream 1 := 1 (CSI Port B)
Stream 2 := 2 (CSI Port C)
Stream 3 := 3 (CSI Port D)
Stream 4 := 4 (CSI Port EF)
Stream 5 := 5 (CSI Port GH)
for example,
if you had a sensor connect to CSI-G,
the port-index device tree property should be indicate as below.
Sensor_out (port-index= 6) → CSI_in (port-index= 6) → CSI_out (port-index= 6) → VI_in (port-index= 5)
please download [Xavier Series (SoC) Technical Reference Manual] from Jetson Download Center,
you should also check [Multimedia Complex]-> [Camera Subsystem]-> [Figure 7.9 External Connectivity Diagram] for reference.
thanks
