Further drill down the issue and found it was failed while OHS config.

#########

Hence we decided to run FS_CLONE, because we see prepare phase failed during CONFIG_CLONE Patch File System from Run File System,

Below are the steps to follow.

Fix

==

1) Abort the cycle adop phase=abort

2) Clean up the cycle, we can use cleanup_mode=FULL (optional)  adop phase=cleanup

3) adop phase=fs_clone

Then run the prepare phase again. It will be completed.

adop phase=prepare

Thanks.
