Is there a way to do HW-assisted clock division with the TX2 with a clock coming in via GPIO? e.g. perhaps the PWM frequency divider can be fed from a GPIO pin? Even a hack approach would be interesting, as long as I don’t have to deal with Linux kernel latency doing GPIO.
This is very low frequency, the clock would be 30hz. The reason for looking for a HW approach is the latency needs to be very low, ideally in the microsecond range, though I’ll take what I can get ;-)
