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().
