Function Documentation

__cmsis_start()

__STATIC_FORCEINLINE __NO_RETURN void __cmsis_start

(

void

)

Initializes data and bss sections.

This default implementations initialized all data and additional bss sections relying on .copy.table and .zero.table specified properly in the used linker script.
