Hey guys, I'm working on a project where as I was using the ocp.X/bone_pwm_P9_11 and such in kernel 3.8. I just recently updated my Beaglebone black to kernel 4.1 and couldn't get PWM to work...
I was trying to use dtc, rebuild the device tree overlay. I pulled the old am33xx_pwm from https://github.com/beagleboard/devicetree-source/blob/master/arch/arm/boot/dts/am33xx_pwm-00A0.dts and some of these bad boys bone_pwm_PX_YZ from https://github.com/beagleboard/devicetree-source/blob/master/arch/arm/boot/dts/bone_pwm_P8_13-00A0.dts. I know that these are pretty old, but was just thinking maybe it would work with the new kernel? Then I was able to build these device tree overlays and load them into the /boot/uEnv.txt. However, when I went to /sys/devices/platform, I only saw ocp:pwm and it's nothing like the old kernel 3.8 where you'd have duty, period, and all that good stuff. Is this the right way to access PWM or I had to use the example in the Bacon device tree overlay? If so, is there a document on how to know which PWM pin to export? I've been playing with this new kernel for quite a while now and still haven't got any luck. Any advice or pointers will be greatly appreciated.
