Two projects are given. They use different YP release each.
Projects use also different target platform each. I wonder if differences in structuring metadata- and recipes- directory tree between these two projects result solely from different YP releases in use. Or if these can be a result also of modifications conducted by platform vendors. Any hints in what extend these result from different YP release numbers in use? project A (YP release 2.6) xxxx /yocto/ xxxx/yocto/downloads xxxx/yocto/meta xxxx/yocto/sstate-cache xxxx/yocto/build xxxx/yocto/.repo xxxx/yocto/src xxxx/yocto/prebuilt xxxx/yocto/meta/ xxxx/yocto/meta/poky xxxx/yocto/meta/meta-security xxxx/yocto/meta/meta-clang xxxx/yocto/meta/meta-openembedded xxxx/yocto/meta/poky/ xxxx/yocto/meta/poky/meta xxxx/yocto/meta/poky/documentation xxxx/yocto/meta/poky/meta-poky xxxx/yocto/meta/poky/meta-selftest xxxx/yocto/meta/poky/bitbake xxxx/yocto/meta/poky/.git xxxx/yocto/meta/poky/meta-yocto-bsp xxxx/yocto/meta/poky/meta-skeleton xxxx/yocto/meta/poky/scripts + a set of layers value chain specific, meta-... subdirectories with meta/ as root-point. project B (YP release 2.0, actually backport of some later release which unfortunately is not reflected in poky.conf) yyyy/poky/ yyyy/poky/meta-yocto yyyy/poky/meta yyyy/poky/documentation yyyy/poky/meta-selftest yyyy/poky/meta-selinux yyyy/poky/build yyyy/poky/meta-cust-installer yyyy/poky/bitbake yyyy/poky/meta-yocto-bsp yyyy/poky/meta-skeleton yyyy/poky/scripts + a set of layers value chain specific, meta-... subdirectories with poky/ as root-point. I mean mainly following differences: * Project A places a set of value-chain specific layers/meta-... directories at same directory level as poky. * meta-yocto apparently not present in project A tree * meta-poky apparently not present in project B tree |

OE allows you to build own distributions, so what you are looking at is two different distributions based on different different releases but using same build system ( OpenEmbedded ) over major releases the build system gets changed too in terms of its metadata as well new features and some old cruft removed like usual projects. so you have different releases, and different machines and different distro all contributing to the differences. |

OE allows you to build own distributions, so what you are looking at is twoThanks for input from you. Does this mean shown differences in directory tree is result, a mix of these all listed parameters? I am aware of these are two different distributions. I am aware of these are based on different releases. I am aware of these are two different machines. I am aware of release to release to get several classes of modifications. Actually asked question means how much show differences result from usage of different YP releases. |
