Really any current "rootfs" that can at-least run 2.6.32, will boot fine with this 3.14. The kernel config already includes all the dependices for systemd by default. (I do need to re-add the Android configs). So, really, it should just work, if it doesn't just ping this list and we will get that missing config enabled. > Can use the Angstrom build tool(or other method) to build a Angstrom rootfs > and use the beaglebone 3.14 kernel "out of the box"? > Is there any version dependencies in the rootfs that I need to worry about? > Is there any benefit to look into yocto for me?

Do you have some keywords > regarding important topics that have changed? I guess Device tree is one. Device Tree should be in the books from 2.6 kernel, back then it was mostly a powerpc thing. It wasn't till late in the 2.6.xx/ early 3.x series did device tree's become "bootable" and till 3.10.x when it became "very*" useful. (* multarch became useful, imx+omap same kernel) Regards, -- Robert Nelson http://www.rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
