    @Moderator Hi, I am using SDK1.0. No peripherals attached, just the VOXL2 Board alone.

    @Rowan-Dempster No, that is definitely not expected. PX4 should only be using a small amount of CPU. Can you disable all other services so it's only PX4 running and see if that changes?

      @Rowan-Dempster Can you also post the output of voxl-inspect-services so we can see the CPU usage by each service

        @Eric-Katzfey voxl-px4 and cpu-inspector were the only two services I have running

            @Rowan-Dempster If you run it as a service with voxl-configure-px4 do you see the same issue?

              @tom The output of journalctl -u voxl-px4 could be helpful

                    @Rowan-Dempster If you are running voxl-px4 as a service you need to change your /etc/modalai/voxl-px4.conf file to enable daemon mode. Your log shows you have it disabled DAEMON_MODE=DISABLE

                      @Eric-Katzfey I don't have that .conf file, even after I run voxl-configure-px4 (I just select enable)
