Jetson Xavier CPU issue

When Xavier displays/Encoding 4~2 cameras(FLIR), the CPU becomes 100% full over time.

i386 confirmed that it works without any problems.

[i386 Spec]

  • AMD Ryzen 7 2700 Eight-Core Processor 3.20GHz
  • RAM : 32GB

In addition, even if ‘sudo jetson_clocks’ and ‘sudo nvpmodel -m 0’ are executed to maximize performance in Xavier, the cpu is 100% filled over time.

Hi,
For USB cameras, we support UVC driver by default. Please follow the post to launch the cameras:

Hi DaneLLL,

My camera interface is Ethernet and using eBus SDK for FLIR Camera

Hi,
CPU capability of Xavier may not be able to give equivalent performance to x86 PC. If the driver takes much CPU loading, it is possible to see lower performance on Xavier.

We have camera partners developing camera modules with optimization. You probably can take a look. FYR.
