The R5F CPU utils is having some Cortex R5F CORE functionality like reading the CPU Static Registers of ARM CORTEX R5F CORE.

Features Supported

The system control coprocessor, CP15, controls and provides status information for the functions implemented in the processor. The main functions of the system control coprocessor are:

• overall system control and configuration
• cache configuration and management
• Memory Protection Unit (MPU) configuration and management
• system performance monitoring.

In this section, all the resisters are being read of the System control coprocessor.

• NOTE-> For detail description of these register, one can refer ARM CORTEX R5F TRM.

SysConfig Features

Example Usage

The following shows an example of SDL R5F CPU UTILS API usage by the application.

Include the below file to access the APIs

#include <sdl/r5/v0/sdl_r5_utils.h>

For reading all the R5F CPU Static Register, the below API will be used.

int32_t  sdlResult;
/* Declaration of Global structure to contain all register values*/
SDL_R5FCPU_StaticRegs  pCPUStaticRegs;
 
    /*Read all R5F cpu static registers*/
    sdlResult = SDL_CPU_staticRegisterRead(&pCPUStaticRegs);
 
After calling the above API, All register values can be found into the structure.
