The 32bit core-image-minimal-initramfs should be built when build lib32-iso, e.g.: MACHINE = "qemux86-64" require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "x86" IMAGE_FSTYPES += "iso" $ bitbake lib32-core-image-minimal Exception: FileExistsError: [Errno 17] File exists: '/path/to/tmp/sysroots-components/core2-64/qemuwrapper-cross/usr/bin/crossscripts/qemuwrapper' -> '/path/to/tmp/work/qemux86_64-pokymllib32-linux/lib32-core-image-minimal/1.0-r0/lib32-recipe-sysroot/usr/bin/crossscripts/qemuwrapper' This was because: lib32-core-image-minimal -> core-image-minimal-initramfs core-image-minimal-initramfs -> qemuwrapper-cross lib32-core-image-minimal -> lib32-qemuwrapper-cross So we got the error, build lib32-core-image-minimal-initramfs can fix the problem.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
