You can browse https://layers.openembedded.org/layerindex/ to find more info about layers and recipes.
If you go to the Machines
tab and search for imx8
, you can find devices such as imx8mp-ddr4-evk
, you'll have to find which exact device you need. Sometimes your specific machine won't be there but the appropriate family of machines might be. It look's like meta-freescale would be the layer you would be interested in.
Then going back to the layer index, if you search under recipes you can find netdata
is provided by meta-webserver.
So you would need:
- meta-freescale
- meta-webserver
And their dependencies
- meta-oe
- openembedded-core
And probably some sort of Distro layer e.g. use poky
but add the above layers. See the Yocto quick build reference on how to get started.
