Hello, I'm trying to evaluate the performance of my builds and following the wiki link https://wiki.yoctoproject.org/wiki/Build_Performance to determine the accurate BB and PM values for my builds.
I have set "INHERIT += "buildstats"" in my local.conf and disabled "BB_NUMBER_THREADS" & "PARALLEL_MAKE" during the execution of the build and the script. Executing the script bb-matrix.sh from the BUILDDIR with the command ". ../poky-sumo-19.0.0/scripts/contrib/bb-perf/bb-matrix.sh ." deletes the TMPDIR entirely and then complains 'cp: cannot stat ‘tmp/buildstats’: No such file or directory' for each iteration of BB and PM values. I don't understand where I am going wrong and how do I go about generating the dat file and in turn plotting the graph to determine the performance of the build? Thanks! Dhanush
