CONFIG_ENTROPY_ESP32_RNG¶

ESP32 entropy number generator driver

Type: bool

Help¶

This option enables the entropy number generator for ESP32 SoCs.

With Wi-Fi and Bluetooth disabled, this will produce pseudo-entropy numbers: noise from these radios are used to feed entropy in this generator.

Direct dependencies¶

SOC_ESP32 && ENTROPY_GENERATOR

(Includes any dependencies from if’s and menus.)

Defaults¶

No defaults. Implicitly defaults to n.

Symbols selected by this symbol¶

ENTROPY_HAS_DRIVER if SOC_ESP32 && ENTROPY_GENERATOR

Kconfig definition¶

At drivers/entropy/Kconfig.esp32:7

Included via Kconfig:10 → Kconfig.zephyr:35 → drivers/Kconfig:28 → drivers/entropy/Kconfig:18
