I think I'm missing something here, about the pwm-fan overlay...
On a pi4, I include following lines in /boot/firmware/config.txt:When the system is running, I get the following: Where I see "/trip_point_0_temp:77500" and "trip_point_3_temp:55000", which seems backwards, compared to "dtparam=fan_temp0=55000" and "dtparam=fan_temp3=77500". Is this normal, the arrays of values being in the reverse order? Or what did I do wrong?
