I removed all the 'noexec' stamps from swupdate.bbclass, but still the cooker.log says, that none of the swupdate-image tasks needs execution: NOTE: Setscene stamp current for task 5(../recipes-core/images/swupdate-image.bb, do_populate_sysroot) NOTE: Setscene stamp current for task 6(../recipes-core/images/swupdate-image.bb, do_populate_lic) NOTE: Setscene stamp current for task 7(../recipes-core/images/swupdate-image.bb, do_packagedata) NOTE: Setscene stamp current for task 8(../recipes-core/images/swupdate-image.bb, do_package_qa) NOTE: Setscene stamp current for task 9(../recipes-core/images/swupdate-image.bb, do_package) The funny thing is, that bitbake swupdate-image actually triggers a built of the rootfs. But the task do_swuimage is not even mentioned in the cooker.log! Now only do_swuimage depends on rootfs:do_build, so how can bitbake built a dependency for task it's not running? This is yocto-2.0.2, quite old, but I'd expect this to work on that release still >> I must admit that I feel pretty lost here. > > Best regards, > Stefano -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
