I'm doing a project right now that involves using a micro servo. One is on port P8_13 and another on P9_14.
Everytime I boot the beaglebone it gives me - error: Error enabling PWM controls: Error: ENOENT, no such file or directory '/sys/devices/ocp.3/bs_pwm_test_P9_14.15/polarity' When I check this file it shows a value of '1' inside of it. Where the same file for P8_13 shows a zero. When I change the P9_14 polarity file to 0 the servo works as intended. I'm really confused why the polarity is being set to 1 every time I boot the beaglebone. This also happens if I move the servo to P9_16. I did just upgrade from Debian 7.8 to 7.9 but I don't see how that would change the GPIO behavior. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
