Other Boards and Images
There are other recipes in IoT Yocto that supports different development boards and also different software packages. This section shows how to build for different boards and build a different image.
The boards listed below contains 3rd party boards and boards under development. There is no gurantee that these combinations would work out-of-box.
Build for Other Boards
You can use the
MACHINE variable to assign the board you would like to build:
DISTRO=rity-demo MACHINE=<machine> bitbake rity-demo-image
The available values for
<machine> can be found in the
$BUILD_DIR/conf/local.conf configuration file. A snip of the file is shown below:
# uncomment the line related to the target #MACHINE ??= "i300a-coral" #MACHINE ??= "i300a-pumpkin" #MACHINE ??= "i300a-sb30" #MACHINE ??= "i300b-pumpkin" #MACHINE ??= "i500-evb" #MACHINE ??= "i500-pumpkin" #MACHINE ??= "i350-sb35" MACHINE ??= "i350-evk" #MACHINE ??= "i1200-demo"
You can also locate all the IoT board recipes in:
For example, if the
.conf files in the directory are:
i1200-demo.conf -> mt8395-demo.conf i1200-evb-ufs.conf -> mt8395-evb-ufs.conf i300a-coral.conf -> mt8167-coral.conf i300a-pumpkin.conf -> mt8167-pumpkin.conf i300a-sb30.conf -> mt8167-sb30.conf i300b-pumpkin.conf -> mt8516-pumpkin.conf i350-evk.conf -> mt8365-evk.conf i350-pumpkin.conf -> mt8365-pumpkin.conf i350-sb35.conf -> mt8365-sb35.conf i500-evb.conf -> mt8183-evb.conf i500-pumpkin.conf -> mt8183-pumpkin.conf mt8167-coral.conf mt8167-pumpkin.conf mt8167-sb30.conf mt8183-evb.conf mt8183-pumpkin.conf mt8365-evk.conf mt8365-pumpkin.conf mt8365-sb35.conf mt8395-demo.conf mt8395-evb-ufs.conf mt8516-pumpkin.conf
i350-evk.conf is an alias to
mt8365-evk.conf. In this case, the following
<machine> names are available:
For details, please refer to the BSP documentation.
The IoT Yocto bringup image (
rity-bringup-image) is mostly used for BSP development and board bringup.
The image contains the some tools necessary to validate software and hardware.
rity-bringup-image is designed to be built with the
DISTRO variable set
to the following:
You can use the following command to build the rity-bringup-image:
DISTRO=rity-bringup MACHINE=<machine> bitbake rity-bringup-image
The resulting image is located in
Please note that the same image directory may contain multiple distro images.
For example, if you build both
rity-bringup-image for i350-EVK:
DISTRO=rity-demo MACHINE=i350-evk bitbake rity-demo-image DISTRO=rity-bringup MACHINE=i350-evk bitbake rity-bringup-image
The image directory
$BUILD_DIR/tmp/deploy/images/i350-evk contains both images.
You can use
aiot-flash-tool -i <image-name> to select the image you want to flash.
For example, to flash
aiot-flash -i rity-bringup-image
