This layer provides support for Microchip microprocessors (aka AT91)

For more information about the Microchip MPU product line see:
Linux & Open Source on Microchip microprocessors:

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, 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

- meta-atmel
URI: git://
Branch: rocko

This Layer depends on :
- meta-openembedded
URI: git://
Branch: rocko

- meta-qt5
URI: git://
Tag: v5.9.4

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:// -b rocko

2/ Clone meta-openembedded git repository with the proper branch ready
git clone git:// -b rocko

3/ Clone meta-qt5 git repository with the proper branch ready
git clone git://
cd meta-qt5
git checkout v5.9.4
cd ..

4/ Clone meta-atmel layer with the proper branch ready
git clone git:// -b rocko

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

# POKY_BBLAYERS_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly


BSPDIR := "${@os.path.abspath(os.path.dirname(d.getVar('FILE', True)) + '/../../..')}"

  ${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 \

  ${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
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

11/ Build Atmel demo images
bitbake atmel-qt5-demo-image

Typical bitbake output

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:

for some useful guidelines to be followed when submitting patches:

Nicolas Ferre <>
Patrice Vilchez <>

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>
