Actually, I even tried to manually pass my P8_34 device tree overlay to the
cape manager:
>
> /lib/firmware$ sudo sh -c "echo bone_pwm_P8_34 > $ SLOTS"
Then it looked good, like:
>
root@beaglebone:~# cat $SLOTS
0: 54:PF---
1: 55:PF---
2: 56:PF---
3: 57:PF---
4: ff:P-O-L Bone-LT-eMM
Thanks for the advice, Graham.
After disabling HDMI by editing uEnv.txt, I was able to gain functionality
of these pins:
8_36 (works but requires EHRPWM1A but that is already in use by 9_14)
8_45 (works but requires EHRPWM2A but that is already in use by 8_19)
8_46 (this one seems to work well)
Donovan:
In your Molloy book, read about device trees, which set the default
assignment
of the I/O pins. Also read about the pin-mux. And related topics like
pin-mux helper
and device tree overlays. Then find the reference in the book
to the BBBP8 and BBBP9 header file spread sheets on the we
Also, I chose to explore these pins by doing:
/lib/firmware$ *ls bone_pwm**
as stated on p.231 of Derek Molloy's BBB book..
Thank you!!!
