Help¶

This option signifies the use of an ARMv7-R processor implementation.

From https://developer.arm.com/products/architecture/cpu-architecture/r-profile: The Armv7-R architecture implements a traditional Arm architecture with multiple modes and supports a Protected Memory System Architecture (PMSA) based on a Memory Protection Unit (MPU). It supports the Arm (32) and Thumb (T32) instruction sets.

Direct dependencies¶

CPU_CORTEX_R && !ARM64 && ARM

(Includes any dependencies from ifs and menus.)

Defaults¶

No defaults. Implicitly defaults to n.
