Hi all, I'm running RCN's 3.8.13-bone56 from the eMMC on my BBB Rev C. I'm wanting to used the PWM on P9_14 and P9_16 (EHRPWM1A and B). I've added am33xx_pwm,bone_pwm_P9_14,bone_pwm_P9_16 to my uEnv.txt capemgr.enable_partno line to enable the PWM pins and drivers.
My question is, short of modifying the bone_pwm_P9_xx dts files/rebuild kernel, how does one change the period? I know both P9_14 and P9_16 have to have the same period and I'm curious if it is possible to change the period for both to a new (same) value? I'm also a bit confused as to what sysfs folders to I use. I've read conflicting instructions as to where to change period and duty values: /sys/devices/ocp.3/pwm_test_P9_16.12/period and /sys/class/pwm/pwm1/period_ns (after echo 0 > /sys/class/pwm/export) So, is it possible to change period without modifying the defaults in the dts files and which of the period / period_ns files should I be using to change period?
