This layer provides support for Microchip microprocessors (aka AT91) ==================================================================== For more information about the Microchip MPU product line see: http://www.microchip.com/design-centers/32-bit-mpus Linux & Open Source on Microchip microprocessors: http://www.linux4sam.org Supported SoCs / MACHINE names ============================== 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. - SAMA5D2 product family / sama5d2-xplained, sama5d2-xplained-emmc, sama5d27-som1-ek-sd, sama5d2-ptc-ek - 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: sumo Dependencies ============ This Layer depends on : - meta-openembedded URI: git://git.openembedded.org/meta-openembedded URI: http://cgit.openembedded.org/meta-openembedded/ Branch: sumo Optionally: - meta-qt5 URI: git://code.qt.io/yocto/meta-qt5.git URI: http://code.qt.io/cgit/yocto/meta-qt5.git/ Tag: v5.9.6 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 -b sumo 2/ Clone meta-openembedded git repository with the proper branch ready git clone git://git.openembedded.org/meta-openembedded -b sumo 3/ Clone meta-qt5 git repository with the proper branch ready git clone git://code.qt.io/yocto/meta-qt5.git cd meta-qt5 git checkout v5.9.6 cd .. 4/ Clone meta-atmel layer with the proper branch ready git clone git://github.com/linux4sam/meta-atmel.git -b sumo 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-microchip 7/ Add meta-atmel layer to bblayer configuration file vim conf/bblayers.conf # POKY_BBLAYERS_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-multimedia \ ${BSPDIR}/meta-qt5 \ " BBLAYERS_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 ??= "sama5d2-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 demo images bitbake atmel-qt5-demo-image Typical bitbake output ====================== Build Configuration: BB_VERSION = "1.38.0" BUILD_SYS = "x86_64-linux" NATIVELSBSTRING = "universal" TARGET_SYS = "arm-poky-linux-gnueabi" MACHINE = "sama5d2-xplained" DISTRO = "poky-atmel" DISTRO_VERSION = "2.5.1" TUNE_FEATURES = "arm armv7a vfp thumb neon callconvention-hard cortexa5" TARGET_FPU = "hard" meta meta-poky meta-yocto-bsp = "sumo:51872d3f99e38f9d883ab0a8782ceecb41822fd0" meta-atmel = "sumo:6880f31be5bbe50594613617fcdfb5ce9c16e292" meta-oe meta-networking meta-python meta-multimedia = "sumo:be79b8b111a968efdbe5e1482d0c246d0b24763e" meta-qt5 = "HEAD:49e9d9a73b5c6e3d6eab88dc0005305e85b1a62d" 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@microchip.com> Patrice Vilchez <patrice.vilchez@microchip.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>
