This Layer depends on:
-
meta-openembedded URI: git://git.openembedded.org/meta-openembedded URI: http://cgit.openembedded.org/meta-openembedded/
-
meta-atmel URI: git://github.com/linux4sam/meta-atmel.git URI: https://github.com/linux4sam/meta-atmel.git
Optionally for SDK building:
- meta-qt5 URI: git://github.com/meta-qt5/meta-qt5.git URI: https://github.com/meta-qt5/meta-qt5
Build has been tested under Ubuntu 22.04 LTS. Anyway you need to install these required packages:
$ sudo apt install gawk wget git diffstat unzip texinfo gcc build-essential chrpath socat cpio python3 python3-pip python3-pexpect xz-utils debianutils iputils-ping python3-git python3-jinja2 libegl1-mesa libsdl1.2-dev python3-subunit mesa-common-dev zstd liblz4-tool file locales libacl1
$ sudo locale-gen en_US.UTF-8
$ sudo apt install make python3-pip inkscape texlive-latex-extra
$ sudo pip3 install sphinx sphinx_rtd_theme pyyaml
0/ Create a directory.
mkdir kirkstone_sama
cd kirkstone_sama
1/ Clone yocto/poky git repository with the proper branch ready.
git clone https://git.yoctoproject.org/poky && cd poky && git checkout -b kirkstone yocto-4.0.13 && 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 kirkstone 79a6f6 && cd -
3/ Clone meta-atmel layer with the proper branch ready.
git clone https://github.com/linux4sam/meta-atmel.git -b kirkstone
4/ Clone meta-arm layer with the proper branch ready
git clone https://git.yoctoproject.org/meta-arm && cd meta-arm && git checkout -b kirkstone yocto-4.0.1 && cd -
5/ Clone meta-thornxt layer with the proper branch ready.
git clone https://github.com/thorrockstar/meta-thornxt.git -b kirkstone
6/ Enter the poky directory to configure the build system and start the build process.
cd poky
7/ Inside the .templateconf file, you will need to modify the TEMPLATECONF variable to match the path to the meta-atmel layer "conf" directory:
gedit .templateconf
export TEMPLATECONF=${TEMPLATECONF:-../meta-atmel/conf}
8/ Initialize build directory and set compiler.
source oe-init-build-env build-microchip
9/ Add meta-thornxt layer to bblayer configuration file.
Make sure that you have no white spaces left to "BBLAYERS ?=" and the other variables when editing the text block.
gedit conf/bblayers.conf
BBPATH = "${TOPDIR}" BBFILES ?= ""
BSPDIR := "${@os.path.abspath(os.path.dirname(d.getVar('FILE', True)) + '/../../..')}"
BBLAYERS ?= "
${BSPDIR}/poky/meta
${BSPDIR}/poky/meta-poky
${BSPDIR}/poky/meta-yocto-bsp
${BSPDIR}/meta-openembedded/meta-oe
${BSPDIR}/meta-openembedded/meta-networking
${BSPDIR}/meta-openembedded/meta-python
${BSPDIR}/meta-atmel
${BSPDIR}/meta-thornxt
${BSPDIR}/meta-arm/meta-arm
${BSPDIR}/meta-arm/meta-arm-toolchain
"
BLAYERS_NON_REMOVABLE ?= "
${BSPDIR}/poky/meta
${BSPDIR}/poky/meta-poky
"
10/ Edit local.conf to specify the machine, location of source archived, package type (rpm, deb or ipk) Pick one MACHINE name from the "Supported SoCs / MACHINE names" chapter above and edit the "local.conf" file. Here is an example:
Make sure that you have no white spaces left to "MACHINE ??=" and the other variables when editing the text block.
gedit conf/local.conf
[...]
MACHINE ??= "sama5d3-xplained"
[...]
PACKAGE_CLASSES ?= "package_ipk"
[...]
USER_CLASSES ?= "buildstats"
[...]
INIT_MANAGER = "sysvinit"
[...]
DISTRO ?= "poky-atmel"
[...]
ENABLE_BINARY_LOCALE_GENERATION = "1"
[...]
GLIBC_SPLIT_LC_PACKAGES = "0"
[...]
GLIBC_GENERATE_LOCALES += "en_US.UTF-8"
[...]
IMAGE_LINGUAS += "en-us"
IMPORTANT
11/ Double check that in the kernel configuration 'General Setup->Timers subsystem->High Resolution Timer Support' has been turned off as well as 'General Setup->Timers subsystem->Timer tick handling' is set to 'Periodic timer ticks'. This should be done by the 'defconfig' but double check before building because it is cruicial.
12/ Build Thor demo images
bitbake thor-nxt-image
