The example purpose is to configure a memory region as privileged read only region and tries to perform read and write operation in different mode. If the access is permitted LED1 is toggling. If the access is not permitted, a memory management fault is generated and LED2 is ON. To generate an MPU memory fault exception due to an access right error, uncomment the following line "PrivilegedReadOnlyArray[0] = 'e';" in the "stm32_mpu.c" file. @par Directory contents - CortexM/MPU/system_stm32f4xx.c STM32F4xx system clock configuration file - CortexM/MPU/stm32f4xx_conf.h Library Configuration file - CortexM/MPU/stm32f4xx_it.c Interrupt handlers - CortexM/MPU/stm32f4xx_it.h Interrupt handlers header file - CortexM/MPU/main.c Main program - CortexM/MPU/main.h Main program header file - CortexM/MPU/stm32_mpu.c Cortex-M4 MPU regions Access rights file - CortexM/MPU/stm32_mpu.h Header for stm32_mpu.c module - CortexM/MPU/Linker Directory containing liker file for each toolchain @par Hardware and Software environment - This example runs on STM32F405xx/407xx, STM32F415xx/417xx and STM32F427xx/437xx devices. - This example has been tested with STMicroelectronics STM324xG-EVAL (STM32F40xx/ STM32F41xx Devices) and STM32437I-EVAL (STM32F427xx/STM32F437xx Devices) evaluation boards and can be easily tailored to any other supported device and development board. @par How to use it ? In order to make the program work, you must do the following: - Copy all source files from this example folder to the template folder under Project\STM32F4xx_StdPeriph_Templates - Open your preferred toolchain and setup your project configuration as follows - Add the required example files - stm32_mpu.c

- For TrueSTUDIO toolchains you have to follow these instructions - In the project properties window, select C/C++ Build->settings node then the C Linker->General node and use "stm32F_flash_ROAarray.ld" as Script File. This linker is configured for STM32F4xx. It should be updated to use it with other STM32 devices.

- Select the project workspace related to the used device - If "STM32F40_41xxx" is selected as default project Add the following files in the project source list: - Utilities\STM32_EVAL\STM3240_41_G_EVAL\stm324xg_eval.c - stm32_mpu.c - If "STM32F427_437xx" is selected as default project Add the following files in the project source list: - Utilities\STM32_EVAL\STM324x7I_EVAL\stm324x7i_eval.c - stm32_mpu.c - Rebuild all files and load your image into target memory - Run the example *
