Startup

Atollic TrueSTUDIO® includes readymade support for booting the CPU, initializing the runtime environment and starting the C/C++ application. The following steps are needed to start an embedded system:

• Initializing the interrupt vector table with a reset interrupt handler
• Initializing the stack pointer to an address in RAM
• Call SystemInit()to enable further hardware initializations from C
• Copying constant initialized variable data from Flash to RAM
• Calling constructors (C++ only)
• Jump to main()

Our startup code provides the above functions, and once the above reset sequence is performed, control is transferred to main() and the C/C++ application.
