Hello
We are developing a system based on FPD-Link III Deserializer Hub DS90UB954.
I modified the DTS to enable 4 channels on CAMERA_A and CAMERA_C (index 0 and 2). The channels are virtual and indexed as 0 and 1 in each VC_ID. Attached you will find the file dts for my configuration.
ingenium-rhead-mt9p031nv.dtsi.txt (14.0 KB)
The issue is
- If i try to capture with V4L2 1 frame from VC_0 and VC_1 all works, I’m able to capture the frame correctly—> this means that the module and thephysical layer is correctly configured.
v4l2-ctl -d /dev/video0 --set-ctrl bypass_mode=0 --set-fmt-video=width=1280,height=720,pixelformat=GB12 --stream-mmap --stream-count=1 --stream-to=image0.raw
v4l2-ctl -d /dev/video1 --set-ctrl bypass_mode=0 --set-fmt-video=width=1280,height=720,pixelformat=GB12--stream-mmap --stream-count=1 --stream-to=image1.raw
- If I try to capture from sensor-id=0 from gst, it works
gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! ‘video/x-raw(memory:NVMM), width=1280, height=720, format=(string)NV12, framerate=(fraction)30/1' ! nvoverlaysink
- If I try to capture from sensor-id=1 from gst, it doesn’t works
gst-launch-1.0 nvarguscamerasrc sensor-id=1 ! ‘video/x-raw(memory:NVMM), width=1280, height=720, format=(string)NV12, framerate=(fraction)30/1' ! nvoverlaysink
Error is:
from element /GstPipeline:pipeline0/GstNvArgusCameraSrc:nvarguscamerasrc0: CANCELLED
So it seems to be something related to the sections after the CSI part, I suppose.
What I need to do is acquire from the deserializer, that acquires 2 streams from 2 cameras, with virtual channel mode. The stream goes trought the CSI section (CSI_A, port 0 and 1).
I think that the v4l2 grabs data after CSI part, is it true? so I think that there is something after in VI part or after in ISP part to configure?
Maybe there is something related to the lanes? The input lanes are 4 (for 2 sensors in virtual channel mode, time multiplexed)

- the device are created on /dev
