That's what I'm trying to get going now. Actually first the PWM for spindle
speed and then I'll create the second PWM for charge pump.
Having a lot of trouble with the PWM for the spindle. I've added what I think
are the correct motion.spindle- ... but all I can get on the AXIS screen are
Making progress.
Scope shows PWM and DIR on correct pin. Buttons work. + button however
increases speed reported value above 3000 RPM when examined with HAL meter even
though PWM reached 100% at 3000 RPM. (50 RPS)
Still missing something.

Just an update. I have a 501.9 Hz square wave now coming out DB25-17. The
simple answer was that I needed to change to
addf charge_pump.0 servo-thread
The .0 was the issue.
The next issue, and I'm not sure how to get around this is the servo thread is
too slow and doing something
Just a shot here cuz I don't use a BB, or MK much, or charge pumps and I
haven't written a hal file in a year lol..
Anyway if I know the purpose of a watchdog timer and the issue you have is
trying to generate reliable pulses from a hal software component running on
a servo thread? Why not
If you just need a charge pump signal, use the PWM function on the PRU
(alternately, you could use a stepgen instance, but that's more code
overhead).
