Hello everyone: I'm just tried servo motor in beaglebone black, but look like it's doesn't working. My debian kernel version is: 4.1.6-ti-r17 PWM: P8_19
I have referenced from here(am33xx_pwm-00A0.dts, BB-PWM2-00A0.dts): https://github.com/beagleboard/bb.org-overlays and Adafruit_BBIO simple code(last version): https://learn.adafruit.com/controlling-a-servo-with-a-beaglebone-black/the-python-console but it always told me: Traceback (most recent call last): File "test.py", line 6, in <module> PWM.start("P8_19", 50, 1000, 1) IOError: [Errno 2] No such file or directory: '/slots' How can I check PWM is ready? I have checked it load in my bone_capemgr. root@beaglebone:~# cat /sys/devices/platform/bone_capemgr/slots 0: PF---- -1 1: PF---- -1 2: PF---- -1 3: PF---- -1 4: P-O-L- 0 Override Board Name,00A0,Override Manuf,BB-SPI0-01 5: P-O-L- 1 Override Board Name,00A0,Override Manuf,am33xx_pwm 6: P-O-L- 2 Override Board Name,00A0,Override Manuf,BB-PWM2 Have any one can give me suggestion?
