CONFIG_ENTROPY_STM32_RNG

STM32 RNG driver

Type: bool

Help

This option enables the RNG processor, which is a entropy number generator, based on a continuous analog noise, that provides a entropy 32-bit value to the host when read. It is available for F4 (except STM32F401 & STM32F411), L4 and F7 series.
