  • How can a system update be done via the internet?

    Garz & Fricke usually offers several operating system versions for different devices, which are also regularly updated. These OS versions can be installed as a complete image over the Internet on the devices.

    First of all, the device must be connected to the Internet via the network.
    Then switch to the Flash-N-Go system with the following console commands:

    $ bootselect alternative
    $ reboot

    The device then boots into Flash-N-Go System and the corresponding boot logo appears on the screen. Activate DHCP via the following command:

    $ sconfig dhcp on

    Now the desired image can be downloaded via the internet. The following example refers to a Yocto Rocko image for a Santaro device.

    $ udhcpc; export TFTP=http://support.garz-fricke.com/products/Santaro/Linux-Yocto/Releases/Yocto-jethro-11.0-r8139-0/prebuilt_images;
    curl ${TFTP}/GUF-Yocto-jethro-11.0-r8139-0-IMX6GUF-fng-install.sh | sh

    You can first enter the following path in the web browser: “support.garz-fricke.com/products/” and then continue to complete the path through the device up to the folder “/prebuild_images”. After the expression “curl $ {TFTP}/” enter the name of the corresponding SH-Scrip and the expression " | sh ". The script can be found in the folder “/prebuild_images”. The installation process takes a little time. During the installation, the individual commands are constantly output on the console.

    Finally, the regular OS is activated via the following commands and the device starts with the new operating system.

    $ bootselect regular
    $ reboot

    load -b 0x12018000 -r root.cpio.gz
    load linuximage
