I'm have trouble reproducing this. I'm running *cat /etc/dogtag* BeagleBoard.org Debian Image 2016-01-24 *cat $SLOTS * 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,cape-universaln
Wire an LED to P9_14 and then: *cd /sys/class/pwm/pwmchip3* *echo 0 > export* *cd pwm0* *echo 1 > enable* *echo 1000000000 > period* *echo 500000000 > duty_cycle* No errors, but the LED doesn't flash. The LED does turn on when I control via the GPIO. What am I missing? --Mrk On Wednesday, July 22, 2015 at 4:46:02 AM UTC-4, dogan yazar wrote: > > I verified it locally yesterday and it works fine.
