i have project using yocto building libraries including gstreamer. found out need patch gstreamer element creating new bitbake recipe patch..
i have run bitbake image name parameter rebuild whole yocto (which quite long):
machine=some_machine nice bitbake yocto-etc-etc how rebuild part need , not whole yocto? heard devtool, not sure how use that.
certainly, easy do. specify recipe want build instead of image name, example if main gstreamer recipe had changed (which @ least in current versions called gstreamer1.0):
machine=some-machine bitbake gstreamer1.0 note name expected on command line recipe name or provides in recipe, , not runtime package name.
regarding devtool, can put environment can more make changes source recipe , generate patches them, actual building part discussing here doesn't change. can find more information on how use devtool in yocto project development manual
