Just a BIG warning, dtb-rebuilder is gaining a dependency* on a patchset in the v3.14.x repo: https://github.com/RobertCNelson/ti-linux-kernel-dev/tree/ti-linux-3.14.y/patches/beaglebone/pinmux-helper as of last week, both the hdmi/usart pins need pinmux-helper enabled, otherwise (hdmi & usart) will not enable correctly. Pretty soon, the "3.14-ti" branch name of the repo will make more sense... I'm forward porting the pinmux-helpher patches to my v3.16/v3.17 bone trees but there will be lag, as i'm human.. ps, the docs are here: http://elinux.org/Beagleboard:Capes_3.8_to_3.14#Custom_dtb but i'd rather get all the capes working first, before writing up something that may change.. > > Attached are the device tree files/includes dts/dtsi which I made for use > with the 3.16+ kernels.

Sorry, i haven't tried that eqep driver outside of 3.8, so i can't verifry if it works 3.8+ 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.
