You'll have to edit the pinmux values if you want to change the slew rate. I have entries to enable input, output, and pull-up/pull-down, but there's a limit to how many combinations make sense to have in the default device tree. Playing with slew rate is one of the things that pushes you towards making your own device-tree with whatever custom settings you need for your hardware. If you want to use the universal overlay, you would need edit the pinmux values: <example pinmux settings you need to change for P8, pin 7): https://github.com/cdsteinkuehler/beaglebone-universal-io/blob/master/cape-universal-00A0.dts#L173-L183 I have entries to enable input, output, and pull-up/pull-down, but there's a limit to how many combinations make sense to have in the default device tree before requiring you to craft your own. -- Charles Steinkuehler [email protected] -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
