Jetson USB Camera Hang

Autonomous Machines Jetson & Embedded Systems Jetson TK1
1

We have facing a strange problem when we are using USB camera in Jetson TK1.
Issue

  1. We external USB 3.0 HUB on Jetson and connected 2 USB 3.0 camera.
  2. We are getting 5MP frames from both the camera and encoding it to H264 and streaming it over Ethernet using gstreamer command.
  3. While doing so after 10 min we got kernel opps and device hangs.
    Did any one faces this kind of error? Is there any known issue or limitation in USB 3.0 or H264 encoder?

I have pasted the error below,

Hi Jeslin,

There is a new TK1 firmware for similar case, please refer below link to update it:
[url]https://devtalk.nvidia.com/default/topic/936302/jetson-tx1/support-for-multiple-high-resolution-usb-3-0-cameras-/post/4928235/#4928235[/url]

I’m not sure whether it can help more, but it’s better to estimate the USB 3.0 bandwidth with the device you are using first, and please make sure set CPU to max freq to prevent event ring full problem.

Besides, if only do the H264 encoding on device, not do the streaming via ethernet, could the device hang?

Thanks
