There're 20 pins for hardware PWM output on BBB (11 on Pocket). Find a list

Sorry, I'm really new to this. Is it necessary to provide the JTag
connnection to Beaglebone Black to work with sdk rtos?

I tried booting Beaglebone Black with pre-built sdcard.img provided in the
path
C:\ti\processor_sdk_rtos_am335x_6_03_00_106\prebuilt-sdcards\evmAM335x\sd_card_img.
I connected the board using USB-TTL to view the booting procedure, but it
shows:
*StarterWare Boot Loader*
*BOARDInit status

I found a useful article on device tree overlays here:

After uncommenting the line disable_uboot_overlay_addr3=1 in /boot/uEnv.txt,
PWM is working on pin 8_13, even with the Prototype Cape attached.

Here’s the Protocape I’m using.

Hi Neil,
Not sure if you already solved this but you are getting this error due to
following:

I’ve investigated a bit more. First, and I should have done this sooner, I
removed all the capes I’m using and tested the bare Beaglebone black. Success,
all four PWMs work.
Then I began adding capes one at a time. I found that when a Prototype Cape is
used, PWM is no longer available on

Hi,
Trying to install old kernel 3.8.13 on the newest Debian 10 IOT image from
beagleboard.org. (Want to have Python 3.7. But all my configuration of
GPIO, UART (with RS485) is based on the old capemanager)
Used "sudo apt-get install linux-image-3.8.13-bone86" and then commented

OK, 3 of 4 PWM pins are working, but still no luck with P8_13.
I can see that Adafruit_BBIO is writing values into
/sys/class/pwm/pwm-7:1/duty_cycle but no output is being generated.
debian@beaglebone:/sys/class/pwm/pwm-7:1$ cat duty_cycle
20
debian@beaglebone:/sys/class/pwm/pwm-7:1$
Thanks for that, I’ll look at it again today. I may have mucked something up
while digging into the /sys/class/pwm file structure or forgotten to do
GPIO.cleanup() or some other combination of things.

P8_13 is working for me as a PWM output, and I am using the Adafruit BBIO
library. I’m using the latest image with LXQT (Debian 9.9 I believe).
