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 and G4 series.
Direct dependencies¶
(ENTROPY_GENERATOR && SOC_STM32F427XX && SOC_SERIES_STM32F4X) || (SOC_FAMILY_STM32 && ENTROPY_GENERATOR)
(Includes any dependencies from ifs and menus.)
Defaults¶
