    I have flashed the voxl-dev branch files to the voxl 2's /etc/modalai/ folder. It seems like voxl-dev branch's voxl-px4-hitl is not an executable file. I am facing this issue.
    voxl2:~$ voxl-px4-hitl
    bash: voxl-px4-hitl: command not found

    How to fix the problem?

    @Tamas-Pal-0 You can get a voxl-dev branch package from here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.4.19-202208111710_arm64.deb. Install that package instead of trying to copy files over manually.

      The voxl-px4-hitl is still missing in the package. I have installed it and tried to run voxl-px4-hitl command. It is not working. I have shared the terminal syntax below. How to fix it?

        Hi Tamas - please run a chmod +x /usr/bin/voxl-px4-hitl and that will enable permissions. After running that, you can run voxl-px4-hitl from any directory and it will work.

            @Tamas-Pal-0 Looks like px4 was already running. It was probably automatically started on system bootup using the systemd service. What is the output from voxl-inspect-services?

                    @Tamas-Pal-0 voxl-px4-hitl isn't missing. Your screen shot shows you executing it. But as I said in the earlier response you already have px4 running and when you execute the command it won't allow you to run a second instance of px4.

                      @Eric-Katzfey The voxl-px4-hitl is still missing. I followed all the steps but the executable file voxl-px4-hitl is still not there

                      @Tamas-Pal-0 In order to prevent px4 from running automatically in the background as a daemon on system startup use systemctl disable voxl-px4 and then sync. Reboot voxl 2 and then try voxl-px4-hitl again.
