CONFIG_MBEDTLS_ENABLE_HEAP

Enable global heap for mbed TLS

Type: bool

Help

This option enables the mbedtls to use the heap. This setting must be global so that various applications and libraries in Zephyr do not try to do this themselves as there can be only one heap defined in mbedtls. If this is enabled, then the Zephyr will, during the device startup, initialize the heap automatically.

Direct dependencies

(Includes any dependencies from ifs and menus.)
