Build from Source Code

Based on Yocto project, rity-demo-image is used to demonstrate the IoT Yocto BSP. Please follow the instructions below to build the demo images of each board.

Note

• You can download prebuilt demo images from Download page.

• You must setup a Linux host computer to build the images.

Important

You need permission to access the https://gitlab.com/mediatek/aiot/nda to build fully functioned rity-demo-image. You can still build image using only publicly available packages through configuration, but the resulting images have only limited feature set.

To request for the permission, please contact your MediaTek sales.

Important

Please read and agree AIoT Software License Agreement before accessing or using IoT Yocto software. If you do not agree to the terms and conditions of AIoT Software License Agreement, you must not access or use the software.

In v23.1 release, to build private configuration that requires GitLab account and NDA repository access, set the NDA_BUILD configuration variable to 1 after initializing the build environment:

# download recipe with manifests
mkdir iot-yocto; cd iot-yocto
export PROJ_ROOT=`pwd`
repo init -u https://gitlab.com/mediatek/aiot/bsp/manifest.git -b refs/tags/rity-kirkstone-v23.1 -m default.xml --no-repo-verify
repo sync

# build configuration
TEMPLATECONF=$PWD/src/meta-rity/meta/conf source src/poky/oe-init-build-env
export BUILD_DIR=`pwd`

# Enable components that require NDA access
echo NDA_BUILD = \"1\" >> ${BUILD_DIR}/conf/local.conf

# Setup paths for downloads and sstate-cache folders
echo DL_DIR = \"\${TOPDIR}/../downloads\" >> ${BUILD_DIR}/conf/local.conf
echo SSTATE_DIR = \"\${TOPDIR}/../sstate-cache\" >> ${BUILD_DIR}/conf/local.conf

Please skip line 12 above if you don’t have NDA repository access or if you’d like to build a public configuration.

Depending on which board you’d like to build for, assign the MACHINE config variable:

Genio 700-EVK

# fetch all the packages and build rity-demo-image
MACHINE=genio-700-evk bitbake rity-demo-image

The output image is located in $BUILD_DIR/tmp/deploy/images/genio-700-evk. Please refer to Flash Genio 700-EVK to flash the image to the board.

Genio 1200-EVK

# fetch all the packages and build rity-demo-image
MACHINE=genio-1200-evk bitbake rity-demo-image

The output image is located in $BUILD_DIR/tmp/deploy/images/genio-1200-evk. Please refer to Flash Genio 1200-EVK to flash the image to the board.

Genio 350-EVK

# fetch all the packages and build rity-demo-image
MACHINE=genio-350-evk bitbake rity-demo-image

The output image is located in $BUILD_DIR/tmp/deploy/images/genio-350-evk. Please refer to Flash Genio 350-EVK to flash the image to the board.
