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().

Defaults¶

2048 if ARC_MPU_VER = 2 && SOC_NSIM_EM && SOC_NSIM
512 if ZTEST
