The build still doesn't work for me. I found the reason: create archive failed: cpio: write failed - Cannot allocate memory It is a "silly" out of memory error. I tried to solve the problem by adding: export RPM_BUILD_NCPUS=8 at the beginning of build-yocto.sh but it didn't work. I realize that this error might be considered a workstation configuration error at my end but I cannot find a way past it. Any suggestions?
