maybe from other bsp source as a reference ? 2015-05-20 10:48 GMT+08:00 liyaoshi <liyao...@gmail.com>: > > http://community.qnx.com/sf/wiki/do/viewPage/projects.bsp/wiki/TiAm335Beaglebone > > 2015-05-18 10:31 GMT+08:00 Charles Steinkuehler <char...@steinkuehler.net> > : > >> On 5/17/2015 8:03 AM, amir....@gmail.com wrote: >> > I would like to have a PWM output signal from BeagleBone Black.
