Where is the hardware PWM on the Beagley-ai??

does not mention hardware pwm that I could find. The example in the manual does not work. The pinout guide says it has hardware pwm???

Try the overlays…

And if that does not work, try the kernel build you are using along with the /opt/source/dtb-$(KERNEL)-Beagle/build_n_install.sh script (maybe).

I have not tried yet. Testing on Thu. sounds right up my ally. Later for now…

Installed the overlays and that did not help. Also needed that additional i2c bus up and did not see an easy path to that. I started to adding some examples to my github page and then hit a wall.

Hmm. I am out of suggestions for now. I will need to start up the Y-AI and test. I have not tested the PWM capabilities just yet.

I need the hardware ePWM and access to the shadow registers. Also need the eCAP to work. The manual for the 62 has it but the 67 I could not find it so it might just be kernel mode PWM. Beagley has overlays for the ePWM.
