The gpiochip* files are the four banks of GPIO pins. The individual pins will show up as a directory if exported by the kernel, something like: $ ls -1 /sys/class/gpio/ export gpio110 gpio111 gpio112 gpio113 gpio114 gpio115 gpio116 gpio117 gpio14 gpio15 gpio2 gpio20 ... > I should have file system entries for PWM pins I have enabled in the device > tree, but I see nothing under the /sys/class/pwm/ directory. > > Is this where the entries should show up? IIRC how PWM is handled changed in the 3.14 kernel, but I haven't worked with it yet. Try searching through the list, I think there have been a few threads on PWM and the 3.14 kernel. -- Charles Steinkuehler char...@steinkuehler.net -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
