4028 Inverted behavior on EBB42. Even with !fan_part_cooling_pin
I know this is mentioned multiple times here but i can't seem to solve it.
I'm building an VCore 3.1
My 4028 4pin Part cooling fan keeps responding inverted whatever i do. (100% off 1% = full)
I use the EBB42 1.2 toolboard.
In the config.cfg i tried [include RatOS/4pin-fans/part-cooling-fan-100hz.cfg] but got an error:
Pin '4p_fan_part_cooling_tach_pin' is not a valid pin name on mcu 'mcu'
Therefor i copied the content from 4pin-fans/part-cooling-fan-100hz.cfg and placed it in the config.sfg. With the same error.
So i changed 4p_fan_part_cooling_pin to fan_part_cooling_pin.
when placing the code at the same position in config.sfg as the include it works but inverted.
There is no change when using pin: !fan_part_cooling_pin or pin: fan_part_cooling_pin
I use PA3 of my octopus 1.1 as enable pin
When placing the same code in the overrides section of config.sfg it won't work!
when setting any speed the fan blows 100% except for 0% and 100% then it stops
What am i missing?
Your help is much appreciated

If your board has 4 pin fan headers and you want to use them, you can enable them here.
NOTE: If none are uncommented, the default 2pin fan headers will be used.
