CORRECTABLE_ERR with ov7251 camera

I’m trying to use an omnivision ov7251 sensor with my xavier nx. I can talk to the sensor fine but when I try to use the camera I get several errors. I’ve googled but I have no idea what they mean. Is there a way to decode these?

hello bike_works,

what’s your mean about you can talk with the sensor but cannot use it.
may I know your commands or pipeline to access camera sensors.
thanks

This is an arducam ov7251-based module. By “talk with the sensor” I mean I can read it’s chip ID/revision so I know that it’s powered on. Here are a few commands i’ve tried. The OP was from the first

v4l2-ctl \
--set-fmt-video=width=640,height=480,pixelformat=RG10 \
--set-ctrl bypass_mode=0 \
--stream-mmap \
--stream-count=3 \
--stream-to=ov7251.raw -d /dev/video0

gst-launch-1.0 nvarguscamerasrc sensor-id=0 ! \
'video/x-raw(memory:NVMM), width=(int)640, height=(int)480, framerate=100/1' ! \
nvvidconv flip-method=0 ! \
nvoverlaysink

@JerryChang by reducing the frame rate from 100 to 30 I’m able to get the raw 4l2-ctl capture to work and I can verify I’m getting an image through.

If I use nvarguscamerasrc it just bails out though.

well, this ended up being entirely my fault. I had a problem in setting of the frame rate function.
