Any strange behaviour, crashing issues etc, post them here! Problems compiling the firmware should go in the General support section rather than here

Im having trouble with the idle up function, When first enabled before reboot the selected pin works fine (in my case im using Arduino pin D40) after reboot any change on the pin isn't seen by the firmware. Disable idle up, reboot and reselect it makes it work again until next reboot. My pin 40 isn't defined in the pin mapping so i'm not overriding a pre programmed pin.
If i use the input pin for anything else it works fine.

Has anyone else having this problem 202108 firmware?

and no i can't run the current release as im using the STM32F407 and the comms is still too buggy to risk an engine on.

D40 is PE4 on stm32f407.
Look in your init.ino I think it is affected in pinStepperEnable = PE4; //
depending on the PE4 boards is also the K0 button which has an internal pull-up.

Im not using the standard pin map, mine is a custom.
but the pin works when set to anything else, like clutch input pin.

Further testing show the idle up input pin only changes states with a going high input, doesn't matter what the firmware is set too (normal/Inverted) on the STM32
