Note that most of the machine names below, have a SD Card variant that can be built by adding an "-sd" suffix to the machine name.
This Layer depends on :
poky URI: https://git.yoctoproject.org/poky Branch: scarthgap Tag:scarthgap-5.0.3
meta-openembedded URI: https://git.openembedded.org/meta-openembedded Branch: scarthgap Tag/commit:735ae0310870ffce07ce0c55c4f87c20ac161ff9
meta-arm (for optee components) URI: https://git.yoctoproject.org/meta-arm Branch: scarthgap Tag:yocto-5.0
0/ Create a directory mkdir my_dir cd my_dir
1/ Clone yocto/poky git repository with the proper branch ready git clone https://git.yoctoproject.org/poky && cd poky && \ git checkout -b scarthgap scarthgap-5.0.3 && cd -
2/ Clone meta-openembedded git repository with the proper branch ready git clone git://git.openembedded.org/meta-openembedded && \ cd meta-openembedded && git checkout -b scarthgap 735ae0 && cd -
3/ Clone meta-atmel layer with the proper branch ready git clone https://github.com/linux4sam/meta-atmel.git && cd meta-atmel && \ git checkout -b scarthgap 53c6bb && cd -
4/ Clone meta-arm layer with the proper branch ready git clone https://git.yoctoproject.org/meta-arm && cd meta-arm && \ git checkout -b scarthgap yocto-5.0 && cd -
5/ Enter the poky directory to configure the build system and start the build process cd poky If not created yet, add a new "build-microchip" directory: mkdir build-microchip Else, if it's the first time you use Yocto Project templates, and if the build-microchip directory remains from a previous use, we advise you to start from a fresh directory. Keep your build-microchip/conf/local.conf file for reference.
6/ Inside the .templateconf file, you will need to modify the TEMPLATECONF variable to match the path to the meta-atmel layer "conf" directory: export TEMPLATECONF=${TEMPLATECONF:-../meta-atmel/conf/templates/default}
7/ Initialize build directory source oe-init-build-env build-microchip
8/ To build a small image provided by Yocto Project:
[MACHINE=
Example for sama5d2-xplained-sd SD card image: MACHINE=sama5d2-xplained-sd bitbake core-image-minimal
9/ To build the microchip image with no graphics support:
[MACHINE=
Example for sama5d2-xplained-sd SD card image: MACHINE=sama5d2-xplained-sd bitbake microchip-headless-image
10/ To build the microchip image with graphics support (EGT):
[MACHINE=
Example for sama5d2-xplained-sd SD card image: MACHINE=sama5d2-xplained-sd bitbake microchip-graphics-image
