Function Documentation

boot_card()

void boot_card

(

const char *

cmdline

)

Standard system initialization procedure.

You may pass a command line in cmdline. It is later available via the global bsp_boot_cmdline variable.

This is the C entry point for ALL RTEMS BSPs. It is invoked from the assembly language initialization file usually called start.S which does the basic CPU setup (stack, C runtime environment, zero BSS, load other sections) and calls afterwards boot_card(). The boot card function provides the framework for the BSP initialization sequence. For the basic flow of initialization see RTEMS C User's Guide, Initialization Manager.

This style of initialization ensures that the C++ global constructors are executed after RTEMS is initialized.

bsp_start_on_secondary_processor()

void bsp_start_on_secondary_processor

(

struct Per_CPU_Control *

cpu_self

)

Standard start routine for secondary processors.

This function is usually called by low-level startup code of secondary processors or boot loaders starting a secondary processor. The final step of this function is a call to _SMP_Start_multitasking_on_secondary_processor().
