How to re-generate yocto SDK in deploy folder

First time, I use the command

$ bitbake machine-image -c populate_sdk

all process success, and then generated the SDK shell script xxx.sh in the deploy folder.

Then, I want to add a new recipe into the project, then bake it successfully. Next I would like to generate new SDK again, so I delete the SDK folder under deploy, bitbake again, all process success, but NOTHING generated, even I rebake and rebake image, SDK would not generated.

message like:

NOTE: Tasks Summary: Attempted 3760 tasks of which 3760 didn't need to be rerun and all succeeded.

How can I trigger the re-populate processes?

Solution

  • As all the files already generated during your first execution and yocto decides based on time stamp/sstate cache, it is not willing to re-do the same compilation again. Also yocto doesn't track the files in tmp/deploy/sdk/.

    One quick solution could be to use --force, for example

    bitbake machine-image -c populate_sdk -f

    this invalidates the time stamp and re-run the populate sdk command alone again.
