Yocto Build Speed up

General Discussions

Hi,

I am trying to speed up my build in the CI. I have saved DL_DIR and SSTATE to a google cloud storage. But when I restart the build. I get this output:

Step #9 - "build-tx2": Initialising tasks...done.
Step #9 - "build-tx2": Sstate summary: Wanted 2799 Found 0 Missed 2799 Current 0 (0% match, 0% complete)
Step #9 - "build-tx2": NOTE: Executing SetScene Tasks
Step #9 - "build-tx2": NOTE: Executing RunQueue Tasks

So it seems that it’s not taking my sstate and download dir.
I launch the build like this:

source setup-environment tegra
export MENDER_ARTIFACT_NAME=${SHORT_SHA}
export DL_DIR=${_DL_DIR}
export MACHINE=$$_MACHINE
export SSTATE_DIR=${_SSTATE_DIR}
export BB_ENV_EXTRAWHITE="$$BB_ENV_EXTRAWHITE MENDER_ARTIFACT_NAME SOFT_SRCREV 
 DL_DIR MACHINE SSTATE_DIR"
bitbake tegra-tx2

In my CI the MENDER_ARTIFACT_NAME was not working so i followed this Howto: MENDER_ARTIFACT_NAME automatic setup for yocto build
But then all my env var like this:

SOFT_SRCREV BB_ENV_EXTRAWHITE="$$BB_ENV_EXTRAWHITE MENDER_ARTIFACT_NAME" MACHINE bitbake tegra-tx2

were ignored so I added them to BB_ENV_EXTRAWHITE

Best regards
