[yocto] local file update vs rebuild

[Takashi Matsuzawa]

Hello.

Thank you for your comment.


I want to double check.


xxxx = image name

yyyy = recipe within xxxx


Then, I am not sure if doing below will rebuild yyyy from scratch.


$ bitbake xxxx -c cleansstate

$ bitbake xxxx


Especially, I am doing things like below within my yyyy.


SRC_URI += "file://src/*;subdir=local"


I want to be sure that, if I make modification to the local files (referred to as file://... path within SRC_URI variable of xxxx recipe), the changes are reflected to the final image.

(Not explicitly specifying -c cleansstate to xxxx).

I think ccleansstate should be good.
