Your uio-test.bb is a separate recipe, and therefore its content has no effect whatsoever on the kernel configuration. The right place to add your "file://uio-test.cfg" is in a .bbappend for the kernel that you are building. But as Bruce said, that kernel must be derived from linux-yocto. -- Best Regards, Patrick Ohly The content of this message is my personal opinion only and although I am an employee of Intel, the statements I make here in no way represent Intel's position on the issue, nor am I authorized to speak on behalf of Intel on this matter. -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
