The following change seems to fix the issue, but I'm not sure if it's a valid fix. Maybe some other fix is needed to avoid having METADATA_REVISION change in the first place!? ```diff --- a/meta/classes/toolchain-scripts-base.bbclass +++ b/meta/classes/toolchain-scripts-base.bbclass @@ -8,4 +8,4 @@ toolchain_create_sdk_version () { echo 'Metadata Revision: ${METADATA_REVISION}' >> $versionfile echo 'Timestamp: ${DATETIME}' >> $versionfile } -toolchain_create_sdk_version[vardepsexclude] = "DATETIME" +toolchain_create_sdk_version[vardepsexclude] = "DATETIME METADATA_REVISION" ``` 93847 1 randy.macleod 2022-08-18 14:50:11 +0000 Sakib, Check if this is reproducible. If it's not (as we suspect), we'll need more info about how to reproduce the issue. YP Triage 93857 2 sakib.sajal 2022-08-18 18:04:13 +0000 I was unable to reproduce the issue, steps provided below. using poky at: commit 7e10918724646a86afd4739ea136dac63d22def3 (HEAD -> master, origin/master, origin/HEAD) Author: Khem Raj <raj.khem@gmail.com> Date: Tue Aug 16 09:58:56 2022 -0700 Steps: # setup build dir bitbake core-image-minimal bitbake -c cleansstate meta-environment-qemux86-64 bitbake -c populate_sdk core-image-minimal All the above steps completed without warnings/errors. Am I missing something? 93886 3 frieder.schrempf 2022-08-24 08:13:02 +0000 Ok, I did some more tests and so far I can only reproduce it on 3.1.14 which is outdated. On the recent Dunfell HEAD (3.1.19) I didn't see the issue anymore, so I assume it was fixed somewhere. I guess you can safely close this report and sorry for the noise! 94592 4 randy.macleod 2022-12-22 16:44:24 +0000 Works on supported branches.
