SECO North Non-GPLv3 Layer
This layer can be used to create an Image for SECO North devices without GPLv3 software.
Build Instructions
The image build without GPLv3 is based on an additional distro:
MACHINE=imx8mpguf DISTRO=guf-wayland-no-gplv3 BBLAYERS=bblayers_imx8.conf source ./setup-environment build
The layer provides a bbclass, that can be used to create new images without GPLv3. There is also a default image, that has similar functionality as the SECO North default image (guf-image):
bitbake seco-image-nogplv3
For a full example of all build steps, please see the README in the machine layer (https://git.seco.com/seco-ne/yocto/layers/meta-guf-machine).
Limitations
A lot of Linux base-utils are released under the GPLv3 license. Because of this, most of these utils are replaced by their BusyBox variant. Also, some non-vital software is simply removed from the image while others are missing some functionality because of removed libraries.
