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, F7, H7 and G4 series.

Direct dependencies¶

(Includes any dependencies from ifs and menus.)
