This layer provides support for Atmel | SMART microprocessors (aka AT91) ======================================================================== For more information about the Atmel | SMART product line see: http://www.atmel.com/products/microcontrollers/arm/ Linux & Open Source on Atmel | SMART: http://www.linux4sam.org Supported SoCs / MACHINE names ============================== - SAMA5D2 product family / sama5d2-xplained - SAMA5D4 product family / sama5d4ek, sama5d4-xplained - SAMA5D3 product family / sama5d3xek, sama5d3-xplained - AT91SAM9x5 product family (AT91SAM9G15, AT91SAM9G25, AT91SAM9X25, AT91SAM9G35 and AT91SAM9X35) / at91sam9x5ek - AT91SAM9RL / at91sam9rlek - AT91SAM9G45 / at91sam9m10g45ek Sources ======= - meta-atmel URI: git://github.com/linux4sam/meta-atmel.git URI: https://github.com/linux4sam/meta-atmel.git Branch: master Dependencies ============ This Layer depends on : - meta-openembedded URI: git://git.openembedded.org/meta-openembedded URI: http://cgit.openembedded.org/meta-openembedded/ Branch: master Optionally: - meta-qt5 URI: git://github.com/meta-qt5/meta-qt5.git URI: https://github.com/meta-qt5/meta-qt5 Branch: master Build procedure =============== 0/ Create a directory mkdir my_dir cd my_dir 1/ Clone yocto/poky git repository with the proper branch ready git clone git://git.yoctoproject.org/poky 2/ Clone meta-openembedded git repository with the proper branch ready git clone git://git.openembedded.org/meta-openembedded 3/ Clone meta-qt5 git repository with the proper branch ready git clone git://github.com/meta-qt5/meta-qt5.git 4/ Clone meta-atmel layer with the proper branch ready git clone git://github.com/linux4sam/meta-atmel.git 5/ Enter the poky directory to configure the build system and start the build process cd poky 6/ Initialize build directory source oe-init-build-env build-atmel 7/ Add meta-atmel layer to bblayer configuration file vim conf/bblayers.conf # LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf # changes incompatibly POKY_BBLAYERS_CONF_VERSION = "2" 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-atmel \ ${BSPDIR}/meta-openembedded/meta-oe \ ${BSPDIR}/meta-openembedded/meta-networking \ ${BSPDIR}/meta-openembedded/meta-python \ ${BSPDIR}/meta-openembedded/meta-ruby \ ${BSPDIR}/meta-openembedded/meta-multimedia \ ${BSPDIR}/sources/meta-qt5 \ " BLAYERS_NON_REMOVABLE ?= " \ ${BSPDIR}/poky/meta \ ${BSPDIR}/poky/meta-poky \ " 8/ 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: vim conf/local.conf [...] MACHINE ??= "sama5d3-xplained" [...] DL_DIR ?= "your_download_directory_path" [...] PACKAGE_CLASSES ?= "package_ipk" [...] USER_CLASSES ?= "buildstats image-mklibs" To get better performance, use the "poky-atmel" distribution by also adding that line: DISTRO = "poky-atmel" 9/ Build core minimal image bitbake core-image-minimal 10/ We found that additional local.conf changes are needed for our QT demo image. You can add these two lines at the end of the file: vim conf/local.conf [...] LICENSE_FLAGS_WHITELIST += "commercial" SYSVINIT_ENABLED_GETTYS = "" 11/ Build Atmel demo images bitbake atmel-qt5-demo-image Typical bitbake output ====================== Build Configuration: BB_VERSION = "1.30.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "universal" TARGET_SYS = "arm-poky-linux-gnueabi" MACHINE = "sama5d2-xplained" DISTRO = "poky-atmel" DISTRO_VERSION = "2.1" TUNE_FEATURES = "arm armv7a vfp thumb neon callconvention-hard cortexa5" TARGET_FPU = "hard" meta meta-poky meta-yocto-bsp = "krogoth:6c1c01392d91f512e2949ad1d57a75a8077478ba" meta-atmel = "master:28c4b5d70f3f7df6f8b108a01f621ca0cf23c1a4" meta-multimedia meta-networking meta-python meta-ruby meta-oe = "krogoth:abd1795729501a13608da67054b9cbf185404be3" meta-qt5 = "krogoth:4ec27e218d725677279d265ac1fc256443d665f7" Contributing ============ To contribute to this layer you should submit the patches for review to: the github pull-request facility directly or the forum. Anyway, don't forget to Cc the maintainers. AT91 Forum: http://www.at91.com/discussions/ for some useful guidelines to be followed when submitting patches: http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded Maintainers: Nicolas Ferre <nicolas.ferre@atmel.com> Patrice Vilchez <patrice.vilchez@atmel.com> When creating patches insert the [meta-atmel] tag in the subject, for example use something like: git format-patch -s --subject-prefix='meta-atmel][PATCH' <origin>
