C Specification

#include <nitro/os.h>
void OS_Init( void );
  

Arguments

None.

Return Values

None.

Description

Initializes the system and performs the following actions:

In the case of the ARM9 processor, this function: ( Initializes the arena (OS_InitArena())( Initializes the communication system between preprocessors (PXI_Init()) (Initializes the lock system for the expanded main memory arena ( OS_InitLock())( Sets initial values for the arenas (OS_InitArenaEx())( Embeds the IRQ stack check data. OS_InitIrqTable() )
( Initializes the IRQ interrupt tables (OS_SetIrqStackChecker())( Initializes the exception display system (OS_InitException())( Does MI-related initialization (MI_Init())( Initializes the V-count alarm system (OS_InitVAlarm())( Initializes the thread system (OS_InitThread())(Initializes the reset system (OS_InitReset())( Initializes the Game Pak library (CTRDG_Init())( Initializes the Card library (CARD_Init())( Initializes the power control system (PM_Init())
In the case of the ARM7 processor, this function: ( Initializes the arena (OS_InitArena())( Initializes the communication system between preprocessors (PXI_Init()) ( Initializes the lock system (OS_InitLock())( Initializes the IRQ interrupt tables (OS_InitIrqTable())( Initializes the exception display system (OS_InitException())( Initializes the tick system (OS_InitTick())( Initializes the alarm system (OS_InitAlarm())( Initializes the thread system (OS_InitThread())( Initializes the reset system (OS_InitReset())( Initializes the Game Pak library (CTRDG_Init())

This OS_Init() function is normally called at the beginning of an application when control is transferred to the user's NitroMain() function. Unless there is a special reason not to do so, call it first.

Tick system initialization and alarm system initialization are not performed on the ARM9's OS_Init(). If necessary, call OS_InitTick() and OS_InitAlarm() (in that order) after OS_Init().
