Hi Alex,
Thanks, Yes I am aware of this issue. I already have a fix for this, I will commit that today,
The 87d06928f90fe910311210a0149d03f3420f593c commit has disappeared from the morello/master branch, probably when they have switched to the 6.1 kernel.
The fix is to use nobranch=1 instead of defining the branch in the SRC_URI.
Pawel
