The directory contains start-up and board level functions. Execution starts in the following order: - sysclock, immediately after reset stm32_rcc calls external clock configuration when CONFIG_ARCH_BOARD_STM32_CUSTOM_CLOCKCONFIG=y is set. It must be set for the VSN board. - boot, performs initial chip and board initialization - ... - nsh, as central application last.
