CONFIG_MAIN_STACK_SIZE
¶
Size of stack for initialization and main thread
Type: int
Help¶
When the initialization is complete, the thread executing it then
executes the main() routine, so as to reuse the stack used by the
initialization, which would be wasted RAM otherwise.
After initialization is complete, the thread runs main().
