I have a project which is using yocto for building libraries including gstreamer. I found out that I need to patch some gstreamer element thus creating new bitbake recipe with patch..
I usually have to run bitbake with image name as parameter which will rebuild whole yocto (which is quite long):
MACHINE=some_machine nice bitbake yocto-etc-etc
How do I rebuild just that part which I need and not whole yocto? I heard about devtool, but I am not sure how to use that.
Answer
you can pass different command to bitbake based on what you need.
To remove temp:
bitbake -c clean gstreamer
To remove temp and sstate cache (I use this most):
bitbake -c cleansstate gstreamer
To remove download as well, and lets begin build starting from do_fetch and all
bitbake -c cleanall gstreamer
Once you are done with either of these clean, which ever suits you, you can simple give build command for the specified:
bitbake gstreamer
