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

Sources

• meta-atmel URI: https://github.com/linux4sam/meta-atmel.git Branch: dunfell

Dependencies

This Layer depends on :

• poky URI: git://git.yoctoproject.org/poky Branch: dunfell Tag: b41d4e46d30ed32e11d68466721a0f4056bad700

• meta-openembedded URI: git://git.openembedded.org/meta-openembedded URI: http://cgit.openembedded.org/meta-openembedded/ Branch: dunfell Tag: 95969f0f5f4264644a5dbfb6d4fb66e2ac3a2cde

• meta-aws (for AWS Greengrass) URI: https://github.com/aws4embeddedlinux/meta-aws.git Branch: dunfell Tag: e34ed15a87e36fa4199c63a184630fa370abac55

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 dunfell

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

3/ Clone meta-aws git repository with the proper branch ready (optional) git clone https://github.com/aws4embeddedlinux/meta-aws.git -b dunfell

4/ Clone meta-atmel layer with the proper branch ready git clone https://github.com/linux4sam/meta-atmel.git -b dunfell

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}

7/ Initialize build directory source oe-init-build-env build-microchip

8/ To build a small image provided by Yocto Project: [MACHINE=] bitbake core-image-minimal

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=] bitbake microchip-headless-image

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=] bitbake microchip-graphics-image

Example for sama5d2-xplained-sd SD card image: MACHINE=sama5d2-xplained-sd bitbake microchip-graphics-image
