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().
Defaults¶
- 2048 if
ARC_MPU_VER= 2 &&SOC_EMSK_EM7D&&SOC_EMSK - 2048 if
ARC_MPU_VER= 2 &&SOC_NSIM_EM&&SOC_NSIM - 2048 if
COVERAGE_GCOV - 512 if
ZTEST&& !RISCV32 - 1024
