You can find a fix in the following overlay: https://github.com/mzakharo/meta-yocto-bone The patches you are looking for are here: https://github.com/mzakharo/meta-yocto-bone/blob/master/recipes-kernel/linux/files/dts/0002-arm-dts-am335x-boneblack-add-cpu0-opp-points.patch https://github.com/mzakharo/meta-yocto-bone/blob/master/recipes-kernel/linux/files/misc/cpufreq.cfg There are lots of other functionality that is missing from yocto-bsp kernel for Beaglebone. I suggest you take at the following repos and scavenge for what you need :P https://github.com/RobertBerger/meta-mainline/tree/daisy-training-v3.14.x/beagle-bone-black-ml/recipes-kernel/linux/linux-yocto-custom/patches https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.14/patches https://github.com/RobertCNelson/ti-linux-kernel-dev/tree/ti-linux-3.14.y/patches -- _______________________________________________ meta-ti mailing list [email protected] https://lists.yoctoproject.org/listinfo/meta-ti
