Hi,
I've followed you procedure fairly carefully, and everything seems to work
fine, except I can't get a signal on an oscilloscope. I've had this
working fine in the old 3.8 kernel, and am trying to get the pwms working
in the latest 4.1.13-bone16 kernel.
Have you verified it actually works
Chris,
This is a custom overlay that I created based on other overlays. I have
not tested this *exact* overlay, since it is extracted from the larger
overlay that matches my additional hardware (about 20 discrete inputs and 2
quadrature encoders). In the end, I think the standard overlays wor
Can you confirm that this works?
I had this loaded before but there was no solution to be found. Is this
overlay a custom overlay you made or something you found from someone else?
I don't believe this overlay is provided with the actual BeagleBone.
By the way, what OS are you running with kerne
I think there are only three PWM units (ehrpwm0, ehrpwm1, and ehrpwm2), but
two of them have an A and a B. I didn't dig too far, but I suspect there
are some constraints on how the A and B can be used, such as maybe they
have to both be at the same frequency, but they could have different duty

Hey Kevin,
Thanks for the guide on enabling PWM on kernel 4.1. I'm a little confused
with PWM now though,...Based on the values that you provide, are you saying
that, there are only 3 PWM's on the Beagleboard? I thought there were more
than that or maybe I was wrong.
The 2nd question would be
I am using the ehrpwm2A PWM on P8_19. Usage of this requires the following
device tree overlay (BB-PWM2-00A0.dts):
/dts-v1/;
/plugin/;
/{
compatible = "ti,beaglebone", "ti,beaglebone-black";
part-number = "BB-PWM2";
version = "00A0";
fragment@0 {
target = <&am33xx_pinmux>;
__overlay__ {
I have the PWM working perfectly on the 4.1 kernel, and I am planning to
post the solution to this thread within a few days.

No, I haven't been able to get kernel 4.1 and PWM working. I haven't looked
at the link you included either. I'll definitely take a look over the
weekend. Hey, can you send me the link to this post on google group? I
can't seem to find my post...
Thanks,

Khanh,
Have you got the PWMs working yet? This documentation
(http://processors.wiki.ti.com/index.php/Linux_Core_PWM_User's_Guide) most
closely matches what I am seeing under the 4.1 kernel, but I had to fall
back on these same old overlays to even see the PWMs. Seem to able to
export, conf
