Arducam imx477 sensor with 4-lane mipi csi interface

hi everybody
i have an arducam with imx477 sensor that work with csi interface and I attached it to jetson nano original nvidia carrier board
but there is a problem here in FPS .
in arducam documentation about this camera module stated that this module support 4-lane mipi csi and could reach 30fps in 4k resolution ( 4056(H) x 3040(V) ) but in jetson nano we only have 2-lane mipi csi so because of this difference I cant reach 30 fps in 4k resolution???
or this is a software problem something like encoding ?? i use gstreamer and very simple pipeline to set nvarguscamerasrc frame size to 3280x2464 and 30 framerate and for sink i used fpsdisplaysink and fakesink to measure fps and it give me 13 fps at the best situation .
I’m very confused.
when i list a formats of camera module with

Hi @abolfazl_asari
In most cases you will be limited in having the same preformance if you reduce the available CSI lanes.
Reducing the CSI lanes has a direct impact on the datarate. You might be able to reak same resolution but it is unlikely to reach the same FPS as 4-lanes.

hello abolfazl_asari,

by default, IMX477 is using 2-lane configuration on Nano series. but… the maximum supported resolution is 3840x2160@30-fps.
did you meant you cannot reach this results? had you also configure system performance to MaxN for evaluation?
you may see-also nvpmodel GUI to change the power-mode.
please refer to this gst pipeline, it disable preview and shows frame-rate only.
$ gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! 'video/x-raw(memory:NVMM),width=3840, height=2160, framerate=30/1, format= NV12' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=I420' ! fpsdisplaysink text-overlay=0 video-sink=fakesink sync=0 -v

hi jerrychange
yes I mean that i can’t reach that fps even without previewing the frames
I test your pipeline sample in 3840x2160 but in this resolution, I get 13 fps
this is the terminal output
last-message = rendered: 100, dropped: 0, current: 13.10, average: 13.45

hello abolfazl_asari,

please share v4l format dumps as following, $ v4l2-ctl -d /dev/video0 --list-formats-ext
I would like to double confirm the JetPack release version, and power mode you’re using, thanks
