Problem when capture video from sensor allied

Do you mean the irq/69-host_sta?

yes, That’s something unusual in my system. You can point me a way to restart drivers NVSI and VI because when I restart 2 drivers it leads to my system core dump. I guess I did wrong to restart two drivers. Thanks

Please check INTR 263

Sorry, I forgot that the interrupt is normal in my system. But I want to ask you how to restart drivers NVSI, VI, ISP. I restarted this driver led to my system restart.

The NVCSI/VI/ISP was reset for each open and close camera.

so, if I open dev/video0 (the device file was created from the driver) then NVCSI/VI/ISP can be reset. oh, it is helpful for me. But my problem is magical. I restart 2 drivers ( manage 2 cameras) but one device works normally and the other does not.

Does these two cameras working separately?

yes, I use two cameras separately but use the same driver.

Maybe can switch camera connection to confirm.

it’s still getting a problem. I have 10 devices but the problem appears randomly. I don’t understand what happened.

What’s do you mean randomly?

which means problems can happen at any time. I cannot predict. Thanks.

If so I would suspect could be the signal problem.

Thanks

what do you mean? the problem with the wire connection? Why every time I restart my system then it runs okay.

This thread is too long to know the current status.
Could you summarize it.

Thanks

I have a problem after capturing for a while. I try to capture 2 videos from /dev/video0 and /dev/video1 by cmd v4l2 but it hang the system. I must type ctrl +C to kill this. I don’t know why I try to restart the driver but I still get this problem. I don’t want to shut down my system. And my problems can happen at any time. I cannot predict.

What’s your camera? Do these camera have HW reset/power down pin to reset it?

my camera is allied vision 1800-507m and allied vision 1800-319m. I just reset my camera by i2c cmd ( don’t have pin reset in my camera to hard reset).

Suppose HW reset would be safe for that.

Thanks

oh Thank you, let me try this.
