CONFIG_IDLE_STACK_SIZE¶
Size of stack for idle thread
Type: int
Help¶
Depending on the work that the idle task must do, most likely due to power management but possibly to other features like system event logging (e.g. logging when the system goes to sleep), the idle thread may need more stack space than the default value.

help
Depending on the work that the idle task must do, most likely due to
power management but possibly to other features like system event
logging (e.g. logging when the system goes to sleep), the idle thread
may need more stack space than the default value.
(The ‘depends on’ condition includes propagated dependencies from ifs and menus.)
