Bruce, I stripped down my bsp later and pushed it github. You can find the BSP .scc (and the files it includes) here: https://github.com/gmccollister/meta-orion-minimal-bsp/tree/master/recipes-kernel/linux/linux-yocto/orion-io The linux-yocto-rt_4.4.bbappend that adds orion-io-preempt-rt.scc to the SRC_URI is here: https://github.com/gmccollister/meta-orion-minimal-bsp/blob/master/recipes-kernel/linux/linux-yocto-rt_4.4.bbappend -George > > Bruce > > >> >> If I don't include it in the yocto-linux-rt_4.4 SRC_URI it's never >> applied at all.
