The Flash-N-Go System is designed as a management system to install and update target operating systems and change the device configurations. Thus it runs with root privileges. This may be a concern for some scenarios. Therefore some security considerations are necessary.

License

The license for the three tools of Flash-N-Go tool suite is as follows:

• Flash-N-Go Boot (the boot loader): This package is published under GPLv2 license. This license information is listed in various places: In the Flash-N-Go manual, as well as contained in the source-package itself in the files COPYING and CREDITS, all available from the website: https://support.garz-fricke.com/projects/Santaro/Flash-N-Go/overview.html

  • The tool “FnG-Boot” is just a single package, i.e. a “package list” is trivial: Just one source code package, also provided on the download page, e.g. GF_iMX6x-FNGBoot-v13.0r3797-src-full.tgz on https://support.garz-fricke.com/products/Santaro/Flash-N-Go/FNGBoot/FNGBoot-v13.0r3797/

  • The source code is a derived work from the “u-boot” bootloader project, which is itself released under GPLv2. All additional code is authored solely by Garz&Fricke / SECO.

  • Hence the tool and its source code is completely licensed under GPLv2

• Flash-N-Go System (the minimal yocto OS distribution): The releases (provided on the same web-page as above) include a full package list including license information for each package.

  • This package list is provided in the Release Notes files, just as for the regular Garz&Fricke/SECO Yocto Rocko. See e.g. https://support.garz-fricke.com/products/Santaro/Flash-N-Go/FNGSystem/FNGSystem-16.0/Flash-N-Go-System-16.0-release-notes.html

  • The yocto source package (e.g. Flash-N-Go-System-16.0-0-IMX6GUF-bsp.tar.bz2) contains the yocto layer source with license information and text in the respective COPYING files.

  • The set of all license texts can also be downloaded in the download area for each release e.g. here https://support.garz-fricke.com/products/Santaro/Flash-N-Go/FNGSystem/FNGSystem-16.0/temp/Flash-N-Go-System-16.0-0-IMX6GUF-fngsystem-image-licenselist.html

  • In summary: The Flash-N-Go System distribution is compiled from a large set of packages with different licenses according to the Release Notes package list.

• Flash-N-Go Update (the updater tool): This package is published under Apache v2 licsense. It is an original Garz & Fricke project. The project is also no longer maintained. It is a python tool and, as such, is distributed as full source-code.

  • The copyright of the source code is completely within Garz&Fricke, now SECO.

  • The license (Apache v2) is noted on the download page, right next to the source code download location https://support.garz-fricke.com/projects/Santaro/Flash-N-Go/overview.html or, directly for the latest version in the file LICENSE-2.0.txt https://support.garz-fricke.com/products/Santaro/Flash-N-Go/FNGUpdate/Flash-N-Go-Update-7.0-r8760/
