There was pwm frequency related bug fixes in 2.4. It’s possible that earlier it was working at a different pwm frequency, try to adjust that in 2.4 and may be that will fix your issue. You have to reload reef-pi every time you update the pwm frequencyOk guys I downgraded to reef-pi 2.2 and my Pwn works so for some reason 2.4 does not work for me?????
