Is there a particular reason you want to build > "core-image-minimal-initramfs" specifically? Building poky-tiny with core-image-minimal worked fine. I didn't understand that this built multiple images (including a cpio.gz), and thought that the default method of building a cpio.gz was to build the <image-name>-initramfs image. So, no, I don't have a particular reason to do this. Also, I'm not sure I am doing the startup initialization with runqemu correctly. I wouldn't have expected any rootfs to be used for this image, but the default invocation of runqemu uses one. An example shows use of a 'ramfs' parameter. I think I need to dig into runqemu and verify args are appropriate for an initramfs. > >> >> Has anyone seen this type of error before, or can provide some >> hints of what to check or adjust to fix this? > > Yup, it's wide characters being required by diffutils and being excluded > by the poky-tiny DISTRO_FEATURES_LIBC assignment.

I'm curious why poky-tiny core-image-minimal built OK, but core-image-minimal-initramfs didn't. I didn't expect any difference in target-side binaries between the two - only some changes in the image build steps. Thanks for the tips. I'll check it out. -- Tim ============================= Tim Bird Architecture Group Chair, CE Workgroup of the Linux Foundation Senior Staff Engineer, Sony Network Entertainment ============================= _______________________________________________ yocto mailing list [email protected] https://lists.yoctoproject.org/listinfo/yocto
